Hi all
Iv got my 290 2006 sherco out of the garage where it's been for the last 18 months.
Put in new fuel, cleaned carb, new plug, cleaned air filter/box etc..
It started straight away to my surprise, BUT!
It's over revving, not just a little but at full revs, and won't cut out. I'm really worried that if I try again the engine will blow up. The only way I could stop was shutting off the fuel.(was going to stick in gear with breaks on but not ridden for a while and clutch sticks a bit, so didn't fancy getting splatted against wall!)
Idle screw on carb is as it was before I cleaned, 3 1/2 turns. Throttle cable seems ok, I can see everything sliding up and down as it should within carb when air box is off.
Something is defiantly stuck open but I don't know what???!!!!
Any help would be great!
Thanks
