earthmover Posted December 20, 2010 Report Share Posted December 20, 2010 Hi folks, Recently picked up an 05 125 Sherco with a kehin carb on it for my girlfriend (she can't kickstart my 250 rev3). Bike starts ok, but fluffs badly off idle. I've removed the carb, cleaned it thouroughly, altered the float tab to stop it pouring fuel out and refitted it (which was a pain). Plug looks reasonable, but with this cold weather I didn't want to mess with the jetting blindly if some other kind soul already had the perfect set up. Cheeky I know, but you never know until you ask. Ta Mark Quote Link to comment Share on other sites More sharing options...
neo Posted December 20, 2010 Report Share Posted December 20, 2010 (edited) Here's my old collection of notes on this... ********************* Jetted Sherco125 - 38/125 Standard Needle Howard Wallace I`m running a KeiHin with 38 pilot, 110 main,JJH Needle. The 125 + 200 have a different crankcase casting, with a shorter length where the reed block mounts.This makes it a bit tighter, and the float bowl drain hex needs a chamfer to clear the top of the gearbox , also need a hose from carb to airbox about 50 mm long. I use the radiator hose off a car with the right diameters. It`s a bit of work to fit up, but the performance gains are well worth it. Cheers, ShercoH 45/118 - stock unleaded fuel. Cheers guys, fitted the b*stard last night. Haven't got my hands on jets yet, running standard 45/125 jets, JJH needle, clip in the middle position. Air screw half a turn out and its near right, any further out and it just bogs down when you whack the throttle open from tickover. ********************** But I will say it's a touch warmer over here at the moment ...hope you have a nice warm garage to work in? Best of Christmas balance. Neo Edited December 20, 2010 by Neo Quote Link to comment Share on other sites More sharing options...

Best of Christmas balance. Neo Cheers for that Neo, wrote down what jets are in mine, but the note is in my (centrally heated) garage next to the bike! Will compare this evening when I get home.

earthmover Posted January 18, 2011 Author Report Share Posted January 18, 2011 Just remembered that I didn't come back to this, so if anyone was wondering: The jetting is 45 pilot, 122 main, JJH needle on the middle notch. After a few more runs with known fuel (Rock Synthesis 2 at 1.5%) shes a lot crisper. My g/f rides around at very low throttle, so have had to teach her to blip it to keep it sweet, whereas with me riding its absolutely fine.
