ok well my bike is ideling fine but as soon as you give it throttle it dies, I cleaned the main jet and that seemed to fix it but then after about 2 minutes of riding it started to die again. any ideas???
thanks

what mods have you done?
does it run better with the choke on? ifso it needs to be richer
if you have done the exhaust, carb and uni ? you may need to richen it up..
try lowering the clip on the jet needle..
how far is the air mixture screw out?
if the air screw is more than 2 turns out from lightly seated you need to go the next size smaller on the pilot jet
Air screw turned in = RICHER
Air screw turned out = LEANER
just a few ideas a think of..

hey man i have the choke mod, exhaust mod, uni filter.
yer mate just didnt think it would be the air/fuel mixture because it was running great then stopped. But im going to keep working on it today and ill let you know.
thanks mate

Hey messed with the air fuel mixture abit today. Seems to sit best at about 2 turns.
But still it runs fine for probably 2 minutes then starts to bog down
Any ideas would be great lol
