My English is not so good but I hope that you can help me! I own a gasgas 450 fse 2007
Last summer my big end failt, so I rebuild my engine with new bearings and a new big end.
After I put everything together it ran beautiful but when use the throttle it stalls every time...
So the bike always starts and runs beautifull untill I touch the throttle! I already checked the valve clearance
and timing. I replaced the fuel pump, throttlehousing inlc injector and sparkplug. But no effect... I've orderd a
fuel pump relay this is my last idea! I also have a spare ignition but i havent tested it. Do you have
any idea's? I hope that you can help!!
And sorry for my english!
With kind regards,
Xander
