raptor 660 will start, but at 1/4 -1/2 throttle....then it backfires real bad while running....then reverse light blinks

if i let off throttle it stalls

was running fine yesterday, until I washed it...now I am baffled

 

Check for water in your air box, take your filter off and clean it..... Check your plugs....

 

Yep, sounds like something got wet.......

 

good advice...I have like a 1/2 in of water in the bottom of my airbox [img]i/expressions/face-icon-small-sad.gif[/img]

I hope once i get everything dry it runs like a champ again

 

Yep it will run fine.
Look under your airbox and take off the clear drain plug from the bottom
and let the water out.....
