Frequently Asked Questions
Where are my frame and engine numbers?
The frame number can be in one of three positions:
1) On the steering headstock. (the frame sub-part number is 0700875)
2) On the top, left rear shock absorber mounting bracket
3) On the right swinging arm pivot plate.
The engine number can be found on the front of the crankcases between the front mounting brackets. Usually under a layer of black exhaust oil. Note: All Stormer (250,370 & 410) engine numbers begin with A250
What fuel & 2-stroke oil should I use in my Stormer?
For road and trail use, we reccomend a good quality mineral based 2-stroke 40w oil such as Fuchs Silkolene Super 2 or Comp 2 mixed at 32:1
This oil is much better for the bushed small end bearing when under extreme load. This Fuchs Silkolene oil is a modern blend which remains stable when mixed with petrol, unlike the old Casrol R.
Silkolene oils are arailable from our web shop - click this link
What oils should I use in my Stormer?
Two Stroke Oil:
Quantity: 7.5 fl oz (210ml)
What should the piston to cylinder clearance be?
Should the clutch be wobbly on the mainshaft?
All Starmaker and Stormer clutch centres have a certain amount of free play on the main shaft splines, even from new. If your clutch cable has snapped inside the clutch casing, check for excessive clutch wobble, as the slots in the face of the basket can cut through the clutch cable. The excessive wobble is probably a combination of worn splines to either main shaft or clutch centre and/or excessive wear in the centre bearing #27831 After studying the clutch assembly, you've probably realised that it is not as straight forward as you might have wished to replace the centre bearing! and that the job will involve removing the clutch housing rivets. Arghh...! The solution... We have a modification, that once carried out, will make the job a piece of cake for subsequent bearing replacements and make the clutch housing & sprocket assembly a much stronger item. Firstly, weld the clutch basket to the sprocket using an electric stick arc welder (a bit tricky admittedly). Then machine out the inside of the housing to allow the bearing to be pressed out. Then machine a circlip groove in the housing, replace the bearing and fit a suitable circlip, to retain it. Job done! We can supply you with a suitable Circlip Part No.FB1357
Are there precautions I should take when washing my Stormer?
Put a plastic bag over the air filter & bung up the end of the muffler. Spray and brush the grime and muck with Silkolene "Pro-Clean" before you get the bike wet. Wash your bike down with a bucket of hot water. Only use additives in the water such as car wash & wax. Do not use house hold detergent as they usually contain salts which will corrode your bike's alluminium and chrome. After washing, always remove the contact breaker cover to allow condensation to dry out. Start your bike after washing off, to disperse any moisture from around the main and big end bearings, especially if using "R" type oils which emulsify with water. Remember to remove the filter cover & exhaust bung before you try and start the bike! Apply Silkolene "All in one" liberally to alloy surfaces and to the rear chain to disperse water and to prevent corrosion. Be careful if you using a pressure washer. Do not direct the washer at engine case joints or into wheel bearings. Polish & cherish! We use Solvo Autosol for the polished alluminium parts and a good quality car polish for the fuel tank and other glass fibre parts.
My clutch is slipping, or dragging what can be done?
2) Your clutch may drag if the clutch cable (#0700792) is not in perfect condition. Any stretch or sticking in the cable will reduce the amount of lift transmitted to the lifting arm. It is essential to use a good cable. Our new clutch cables are made for us by Venhill and are nylon lined.
3) Your clutch may drag if the clutch cotrol lever does not procuce enough pull. Some dog-leg levers, designed for modern bikes, do not produce enough lift.
4) Your clutch may drag if the spirolox circlip (#28216) on the right end of the gearbox main shaft has come off, or if the mainshaft is not shimed to have the correct 0.004" end float.
How do I cure a misfire? or I have no spark
Misfire Diagnosis and Cure
1) Start at the top. Check the spark plug cap and replace the spark plug first of all.
2) Disconnect any kill switch if fitted. If you need to kill the engine in an emergency, hold a strong piece of rag firmly over the muffler outlet and stifle the engine.
3) Unscrew the plug cap, and check to see if the spark will jump 6mm from the end of the wire to earth when cranking the engine over by hand. If it does, check the condition of the plug cap, replace and try again. If the spark will not jump the gap, you have a problem. Read on....
4) Check the H.T. lead and L.T. connections at the coil for frayed wires & poor connections.
5) Check to see if the points gap is correct (.018"), also check to see if the points are chipped, contaminated with dirt/oil/corrosion or if the contact faces have become loose. Replace if suspect. Part No. 869517
6) Check to see if the copper strip joining the rocker arm to the base plate, is shorting out to earth also check if the contact breaker cover is not touching the contacts or copper strip when it is screwed into place. Try the bike with the points cover off and on.
7) Check to see that the condenser has a really good earth. The early cotton reel type condensers are very prone to bad earthing.
8) If the points are sparking excessively, the condenser may be faulty. Replace if suspect. Part No. 31297FB
9) Check to see that the ignition cam has been installed correctly (look for the direction arrow). Be careful if you try to remove the cam they are made from cast iron and are very brittle!
10) Check up and down movement on the crankshaft excessive play in the main bearings can cause "points bounce" and misfires at mid to top end running.
11) Check to see that the flywheel is tight on its taper. If it has come loose, lap it back on with grinding paste, clean and use strong loc-tite on the taper. (don't use loc-tite on the threads) Tighten the nut to 100lb/ft.
12) Remove the flywheel and check to see if the L.T. lead to the points, has chafed through on the back of the flywheel. This is a common cause of misfires.
13) Check the condition of the connections on the stator. Some original stators suffer from coils working loose and poor joints, especially where the rivet passes through the L.T. tag.
14) Check the earth lead for bad joints and poor grounding.
15) Check the coil connections. The wire from the points goes to + (terminal 15)
Note: If the engine has been running for some time with the coil wired the wrong way round, the coil may be producing a weakened spark which will fail under compression. The spark will look nice and blue, but the engine will not start. This can be very misleading because the plug will appear to have a nice blue spark when you check it, the plug will be getting wet but the bike will not start. Replace the HT coil if in doubt.
Why has my small end bush worn out prematurely?
The Stormer small end bushes have a 10mm (.375") diameter oil hole drilled in the end of the rod. Make sure that the bush has not turned in the con-rod, closing off this oil hole.
We have been running our own bikes on Fuchs Silkolene Casterene R40 @ 32:1 for many years without problems. We can highly recommend this castor based oil to you.
If you are experiencing small end problems and are using a modern synthetic oil, don't forget that these modern oils are designed for use in engines where the temperature is maintained and controlled at a lower level by liquid cooling.
These oils are not going to offer you the same protection that a castor based oil can provide.
So, before you seek a complicated solution by fitting needle rollers..... check your oil. It may be as simple as that.
Replace ment small end bush #25091
My front forks leak oil and stick down, what can I do about this?
Is there an easy way to replace the gearbox end cover?
How to fit the gearbox end cover, the easy way:
1) Ensure all the gears are assembled into the gearbox shell correctly and the quadrant assembly is assembled correctly into the end cover.
2) Stick the end cover gasket (#C11905) to the gearbox shell with non hardening jointing compound such as Wellseal, Hylomar Blue or Gold.
3) Stick the cam barrel bearing thrust washer (#27598) onto the gearbox shell bearing face with sticky grease, to hold it firmly in place during the assembly.
4) Rather than use the method of aligning timing marks as described in the Workshop Manual, it is easier to assemble the end cover when top gear is selected.
To time the gears correctly for assembly, think of the cam barrel and the gear change quadrant spindle as two meshing shafts. They rotate in opposite directions. So, rotate the cam barrel fully anti-clockwise. Then with the end cover in your hand (gear lever fitted) apply the thumb of your holding hand to the quadrant to exert some pressure, repeatedly down shift the gear lever to position the quadrant in the top gear position.
5) Carefully position the end cover and gently work it into place.
6) Insert two opposing screws lightly and test for all four gears.
7) If all is OK, insert the remaining screws and tighten diagonally and evenly.
8) Replenish the oil. Silkolene Medium Weight Gear Oil 85W 90.
Quantity: 1 imp. Pint (570ml)
What tips can you give me to improve my AJS Stormer?
The differences these improvements make will transform your stock bike.
1) Fit Good tyres. Cheap tyres will most definitely not offer the same level of grip. Decent tyres will enable you to improve your riding skills and will boost your confidence.
2) Fit a decent muffler. A noisy bike is tiring to ride.
3) Fit our Serrated Foot peg wideners for a firmer, surer foot hold.
4) Fit a Gunnar Gasser twist grip. Medium quick action with the advantage of safely routing your throttle cable sideways out of the way of branches and bushes.
5) Improve your braking significantly by fitting our High Friction Brake Shoes.
6) How to get more power out of my 250 and stop it "gassing up" If you have good engineering skills do the following:
7) Clean up the carburation and improve power by fitting an Amal Mk 2 carburetter. 34-38 for the 250 and 36-38 for the 370/410 depending upon engine state of tune. 32mm is a No No if you want optimum power.
8) Overhaul your ignition. Fit one of our improved stators #27851 for reliability.
9) Fit decent rear shocks for rear end control.
10) Fit our 1" extra thick seat with moulded foam for extra comfort.
11) Overhaul your front forks. Use pro, non foaming fork oil .
12) Use the correct tools. We can supply: flywheel / clutch strap wrench #0710061, diaphragm spring compressor #0710062, engine sprocket puller #0710060, ignition timing tool #0710057. Available form our on line shop.

What are the main differences between a 250 Starmaker and a 250 Stormer engine?
All Stormer engine numbers begin with A250
Starmaker engines are designated 225H with the following variants:
757D Standard Scrambles with wide fins, wide ratio gearbox and twin Amal monobloc carburetters.
490E Road racer version of 757D but with close ratio gears and a tacho drive.
494E Scrambles, but with 6v direct lighting.
826E Scrambles, with single Amal monobloc carburetter.
827E Scrambles with single Amal monobloc carburetter and 6v direct lighting.
834E Road racer with close finned cylinder and head close ratio gears, tacho drive, outrigger contact breakers, and Amal 3GP2 carburetter.
865E as 834E but with 6v direct lighting.
871E trials engine, with wide ratio gears, and Villiers S.25 carburetter, but without lighting
972E Sports roadster, with single Amal carburetter and 12v rectified lighting.
091F Special, with single Amal monobloc carburetter, but without clutch, gearbox and primary drive.
131F Trials engine with 6v direct lighting.
Visually the Starmaker and Stormer emgines look very similar, but in summary the following are the main items of difference:
- The Stormer piston has a shorter back and has shrouded rings covering the ring pegs. The Starmaker has butted rings and a longer back.
- The Stormer crankshaft is wider due to the big end having thrust washers either side of the crank pin, where the Starmaker crank does not have thrust washers.
- The Stormer con-rod has a 3/8” diameter oil hole in the top, the Starmaker rod has a wide (and weaker) oil slot. (fine for trail and trials use)
- The Stormer has reinforced engine mounting point on the crankcases.
- The Stormer crankcases are wider inside to accept the wider crankshaft (see point 2)
- The Stormer has reinforced ribs on the gearbox to frame mounting.
- The Stormer has a removable cylinder liner, the Starmaker line is “cast in”
- The Stormer may have close ratio gear ratios, the Starmaker would have had wide ratio, trials or road race gears.
- The Stormer has a lighter and stronger magneto flywheel than a Starmaker.
- The Stormer has different clutch friction plates to those of a Starmaker. The Starmaker plated have a riveted centre fitted to them.
- The Stormer has a larger diameter clutch centre.
- The Stormer has the spacing of the front chain case screws spaced closer together to give better clearance inside for the primary chain. The Starmaker inner chain case has mounting hole next to the gearbox sprocket, the Stormer does not have this hole. Therefore, they do not interchange.
- The Stormer has a longer clutch operating pin.
- The Stormer has an improved clutch pressure plate (not diaphragm spring)
- The Stormer has an improved gear change quadrant.
- The Stormer has an improved gear change cam barrel.
- The Stormer inner magneto case has a sealing O-ring against the crankcase; the Starmaker casing does not have this O ring.
- The Stormer does not have an exhaust gasket because the exhaust is mounted in a push- fit sleeve. The Starmaker exhaust is clamped to the cylinder and needs a gasket.
What does F-B AJS stand for?
The F-B prefix to the AJS initials refers to the late Fluff Brown. Fluff used this prefix on many of the bikes he produced after buying the Stormer stock from Villiers after the Norton Villiers group went bust. Fluff continued to develop the Stormer from 1974 until the ealy 80's with such enhancements as: Amal Mk 2 carburetters, long travel suspension, snake type exhaust systems, Girling gas shocks, Stadium plastic mudguards, Motoplat electronic ignition, replacement frames, and many more refinements which kept the Stormer based machines modern and a viable option for clubman racers. Many young riders enjoyed sucesses on FB-AJS machines.
Why does my rear brake judder, shudder and vibrate badly?
When you press the rear brake pedal any you feel a strong vibration or shudder through the foot pedal it is probably because the rear brake torque arm has come loose. Check the bolts quite urgently. Failure to do so can cause the brake plate to fracture or the brake torque arm to fail. Remove and Re fit the bolts using Loc-Tite Threadlocking Compound and spring washers.
How do I wire up the points and stator?
What is the best way to start my AJS Stormer?
Starting a large capacity two stroke can be daunting. Follow these steps to make it easier and safer for yourself.
Make sure the bike is in good mechanical condition.
Make sure the contact points are clean and adjusted correctly.
Make sure the ignition timing is set correctly.
Make sure the carburetter is set up correctly and in good condition.
Correct pilot air screw setting helps starting.
Firstly, put on your MX boots to protect yourself from kick-back.
Position yourself and the bike on firm level ground.
If the engine is cold, tickle the carburetter or apply the cold start device.
Stand on the right side of the bike.
Hold the right handle bar in your right hand, Hold under the seat firmly with your left hand, and kick the kickstart lever with your right foot.Make sure the kickstart/footrest are modified so that the kickstart clears the footrest boss, enabling a full swing. Make sure you are wearing a MX boot.
If the engine tries to kick back constantly, check the ignition timing and retard the ignition timing it a little if necessary.
A well set up bike, and a little practise, should start within 3-4 kicks each time.
