Hi all. Here is a question for those knowledgeable in the ways of 2.5 Shercos.

When I go start it I get a kickback. It may happen once or twice but bike still fires after that.

In my experience the only time I ever got a kick back like this was with a PE250 and in that case it was sheared flywheel key and it wouldn't go until that was fixed.

In this case bike starts after a couple of kicks.

Any ideas? Familiar phenomena?

Check your timing http://shercousa.com/pdfs/sherco_ignition_timing_guide.pdf

some of the older Sherco engines do have a tendency to kick back...I never investigated it but I think it's a lot to do with the kick start gearing which is quite fast and the short length start lever plus the lever is set higher from the ground, so when it does kick back you really feel it..I could be dreaming though

Perhaps there's an excessive build up of carbon throughout... Retard the timing and see what happens

Thanks for your responses. I have a look at these suggestions and post again when I've done it..

Cheers

Thanks for the link. Very informative. I have ordered a flywheel puller and will have a look at my timing settings.
