We got a problem with my fathers WR426F 2001. Hotcams
Bike starts backfiring and stalls at load after disassembling and assembling gearbox.
First idea was timing, checked and tried twice, bike idles good.
2nd idea was valves. Checked all clearances, only one valve had bit smaller gap than necessary. Also checked valves for correct closing, put a petroleum up the valves. There wasn't any leak on valves.
Also checked jetting, the main was 175, and we put back as manual says 165
If technicaly everything is OK, whats next, electrical problem? Do someone had the similar problem?
