Hi all,
New owner here down in Hants. Got me a tidy 2002 250 Sherco and it runs very well apart from at low revs. It feels over-rich and not very "crisp", a bit like the choke is half on (it isn't). It always picks up cleanly, its just at steady, low, throttle it doesn't run as smoothly as some other bikes I've ridden and the exhaust note is a pronounced POP POP POP.
All jets etc are standard, #33 pilot, D36 needle 3rd notch down. Turning the pilot screw doesn't seem to affect the problem - it appears to be the next jetting circuit up, but before the needle clip can affect things.
Is this normal for this bike, anything I can do to crisp it up a bit?
Thanks for any advice
TD
