On occasion my Fantic 200 rear kick jumps out of bottom gear.

I have been advised it's likely to be the spring holding the location bearing under the selector drum.

I have stripped the engine and removed the gear cluster and inspected all components, no obvious damage , gears and dogs are sound and no selector fork damage.

I wish to replace the spring in case it's worn , but how do I find a replacement, does any one have a spec or a source, I believe there is no official stock left

Any suggestions

 

 

 

Try a washer or two under the spring which will increase the rate. Frank Pye and bod Wright are the fantic dealers.

Coil Springs Direct, they make them to your pattern, measurement etc.?

Bob Wright isn't doing Fantic stuff anymore.

 

Rather than a few washers you could use a small piece of round bar. This would be the same o.d. as the spring. Adding a squirt of silicon sealant into the spring increase the pressure on the detent ball a tiny amount, sounds like a bodge but it can work. Best off with a new spring. Have you checked the gearbox shaft support bearings? Let us know your findings?

Selector Drum spring replaced, with very slightly longer item.

Problem cured

Hi, I have the same problem with jumping out of gear on my 200 fantic, can I ask where did you get the replacement spring from please?
