cchucky51 - I just realized you weren't the originator of this thread - I hope Mayday is finding this useful also...

If it continues to run good with the black wire disconnected you have 1 of 2 problems...

1) Most likely cause is your RPM Limiter is going bad

2) OR something with your transmission gear position switch is having issues .

NOW, the downfall to the RPM limiter going bad is that if the quad is AWD, the RPM limiter also controls the ground to the AWD system... Although a person can run the quad with the RPM limiter "bypassed" (which is a safety issue as the RPM limiter is in place as a controlled limit of speed in the Reverse gear), depending on the degree of "gone bad" of the RPM limiter, the AWD may not function.

 

it is 2x4 i went out today an started up the bike it ran fine no issue , will try again sat

 

the only plug on the tranny is the nuetral one

 

Don't know if it could cause the backfiring...but there's a clean-out plug on the exhaust canister,near the outlet,that your supposed to periodically remove & cover the outlet to blowout the carbon build-up in the canister

 

JUST TO LET YOU ALL IT WAS THE REV LIMITER ON MY BIKE EVER SINCE I PULLED THE BK WIRE IT RAN FINE BUT WOULD LIKE TO THANK ALL WHO HAD ANY IDEAS OR ADVICE

 

That little black box can cause a lot of problems
