my raptors always run fine then last weekend i had to pull a freind back to the truck when his radiator blew. Now when i give it gas and let off it like back fires or something, makes a pop noise...... I changed the spark plug and that never did anything at all, the plug was fine that I pulled anyhow. My bike got really hot and the fan actually came on when I was pulling him, my fan has NEVER come on scince I added the CT HO kit. Could it of thrown my Valves outa whack? Thanks for any help I ssoo wanta get it running good before the end of June!

 

Anyone got ANY ideas?

 

yeah dude id adjust the valves, check the boots, make sure your idle speed is high enuf, maybe change the plug. did ya have good gas? probabaly.
seems to me you cant adjust the valves often enuf. the intakes tighten and youll get a popping in the intake. bet thats it? i hope so.
simple fix.

 

cool, i'll try that in the next few days, hope that fixes it....... Thx!
