Hi, Not sure this is where I should post this, but I guess someone will tell me if I got it wrong.
I am new to trials (and two strokes), having bought a used Sherco 2012 290 ST 3 months ago. I live in Vanuatu where there is no Sherco dealer or any good motorbike shops, so the small riding fraternity here has to do all our own servicing.
Today I cleaned out the fuel tank and also cleaned the carby, as I suspected there may have been some dirt in the tank (correct).
Put it all back together, and it started almost first kick.
HOWEVER, I had re-routed the throttle cable incorrectly and so it was on full power, so when the bike started it revved to the max for about 5 seconds before I could stop it. I mean it screamed!
After stopping the bike I easily rerouted the throttle cable and expected all to be ok - not so.
Since then I have been unable to start it with the kickstart. Compression seemed down, so I measured it and it was 72psi, but have no idea what it should be. I finally towed the bike behind a car and got it to start, but the power seemed down and it would not idle consistently. When it stopped I was unable to restart it with the kick start again.
A couple of questions if there is anyone that can help.
I have looked hard but been unable to find a service manual for this bike - does one exist?
Could the over-revving have damaged the rings?, reed-valves?, hence causing the starting and idling problem?
Any other thoughts?
Many thanks
Terry
