1987 LT500r was running like a top for many rides, Always started second or third kick Today I was ripping hard was running very nice till.

I was racing mr bro inlaw up a set of forect service roads with switch backs, he on a 421 banshee....pulling high gears up the last hill it bogged down like wa ping wa ping waa waaa waaa... then it would reastard but do the same right away. Then no kick start at all only with pulling it fired  ping ping ping but then the crap wawawa again??

Things I already checked. Carb jets clear yup, spark plug was a bit rich but ok, I switch a new one anyway, coil, and cap also checked.

Just cleaned the filter UNI was ok clean (now very clean), It now kicks back into my boot and I feel uncomfortable trying anything else till I figure out more what it could have cased a perfectly good one kick when warm quad turn into a nightmare?

Any help will be much a peraciated.

Specs mint shape restored almost all stock, Only has a FMF pipe, and UNI filter will get the jet specs for the stock TM 38mm for you guys tommorow.

Thanks for that, You might be on to something. I will check asap

I just pulled the ignition cover and yup you guys are correct. What came first the chicken or the egg, situation.

But it would seem the flywheel nut was not tight enough, and it vibrated a bit and took out the pickup coil. When I took the nut off it cam off with no effort.

The key is also a bit rounded but still in place. I will defently get a new one.

Im kind shocked how small the key and keyway is, seems a bit small for such a big 500cc, its like half the size of a banshee keyway...

Thanks for your help guys, you rock 

Sounds good MotoGeek thanks.
