ok here's what i did. i installed the pair system blockoff plates. that went ok. i then noticed (ol'boy) my fuel injecter stacks were dirty,so i sprayed crab injecter fuild in them to clean. after putting it all back together, bike will not start. it run's for a second then backfires, (nice flame's lol') i think it maybe the carb fuild and or the plugs are now bad. any one had this problem after spraying fuild to clean fi ?

I'd suggest that you've disturbed the plug wires or coil wires when you removed the tank and pieces.

Crank it for a few seconds with the throttle wide open. It won't fire, and that should clear any contaminents.

i will give that a go. my manual is confusing to look at when it come's to the coil wire's, seated on the bike and looking down at the wire's i see, 2 bu/y 3 bl/w 1y/bu 4bl/w thanks as always. 'rockmeupto125'

Thanks joe! worked fine, fired right up afterwards.
