[Rustler88]

my cuz bike was wrecked but has been fixed, ran fine then out of no where it will die he pulls off and turns the key on and off a few times then it will fire and he can drive home. this has worked a few times till now, it fired then immediately died it will do this sometimes and other times it will just crank and not fire....he has changed the plugs.

Does the Kawi have some kind of crash/fuel cutoff system? I had a truck that did the same thing after a wreck. Okay Earz, time to weigh in and scool us all.

^ Most bikes do have a tip switch

Tip switch is where I would start. What year is it?

[Rustler88]

the switch has been apoxyed(pre wreck).......it is an 06

I'm not familiar with epoxying a tip switch. Why was this done? I'm assuming it was an intentional modification and not a "budget" repair.

It sounds like a loose connection somewhere. Start simple and check battery terminal connections, a loose battery connection will cause all sorts of strange problems.

Depending on where/how it was wrecked may be a good starting point in checking for pinched/bare/damaged wiring.

You may also check continuity of the ignition switch contacts. Maybe a loose connection in the switch? You can always bypass the switch temporarily to eliminate the chance of a faulty switch.

No wiring/electrical problem is ever the same, so it's hard to give a "sure-fire" fix without checking a few things. Sometimes these problems are very difficult to track down, other times they jump out at you. Check I out real good and let us know what you find.

I can tear an engine down to nothing, clean it, and put it all back together but the first sign of an electrical problem I take it somewhere....electrical problems are always hard to diagnose so I just don't mess with it.

yeah i think thats the plan.....destination DBM.
