October 13, 200619 yr I have an 06 2.9 Sherco. The bike runs fantastic at all throttle settings. My only concern is when cold starting, with the choke on, the bike revs really high. I'm not overly concerned except I don't like to rev a cold bike this hard. I have stripped and cleaned the carb several times, checked the o ring on top of the choke tube, slide tower, etc. I even tried spraying starting fluid all around the carb and intake boot to check for an air leak, but haven't found anything out of the ordinary. I spoke to RYP about this, they said some Shercos do it and others don't. I can live with it, but if I can fix it, I would like to.
October 13, 200619 yr Hi I found my old gasgas doing this when starting it with the choke on. What I did was to put the choke on and start it but as soon as it is started I used the choke with my fingers playing it to keep the revs at an axeptable level but still keeping the bike on the choke. Hope this helps because it scared the hell out of me when I started it at my first trial! Sean
October 14, 200619 yr Hi, Try laying the bike over at about 45 degrees on the exhaust side after the fuel is turned on, reduces the high speed running on my son's '05 200 Sherco at cold start up. Cheers.
October 14, 200619 yr my old gas gas did this, i found starting it up with the choke on then straight away rocking the bike about calmed the revs down
November 7, 200619 yr i too just hold the choke on with my fingers at an acceptable rpm i,ve had four sherco,s and they have all been the same
November 7, 200619 yr Sound's like it's just doing what a choke should do to get the engine started,no real need to keep it on any longer than that,just switch the choke off and let it warm up naturally.
