Question about 2002 Yamaha YZ 426 F
I own a yamaha YZ426F, it wouldnt start and after kicking it for like ever and ever, it started, but then the exhaust (front) went red hot. Literally! Ive tried starting it since but no luck. Ive got fuel to carb and good spark, the tail pipes been checked and its not blocked. What could be my problem..? My dad sugests checking the valves..??
Please please could you help me, i live on a tiny little island (St Helena) where everything has to be imported, we dont have a bike dealer let alone a bike shop, theres no airport (everything is shipped by ships), i dont know what to do and local moto cross annual races are coming up!

Ive had the same problem. When kicking it over, you should hold onto the break master cylinder cause even the slightest blip on the throttle & its flooded & you'll have a rubber leg in no time. Also when you do finally get it running, Be sure to turn the big black idle knob on the carb up lots & leave it up till well after you have your helmet & gear on, cause if the engine cuts out for any reason after its warm the plug will foul up & another rubber leg will follow. Giving it a couple of good revs just before you kill the engine seems to burn off any excess fuel & prevent plug foul. A pocket full of spark plugs is a must with a yz426, & you want to use the ngk cr8ek plug rather than the ngk cr8e plug that they come with. To sum it all up, black choke knob out(hot or cold), use the decomp leaver to get it to TDC only, dont do what I said not to do & do what I said do. Worked for me hope the same for you!!
