does anybody know what temperature the v is supposed to run at ? i put a temp gauge on mine and it ussually runs at 220 f only 1 time it got as hot as 235 f so i shut it off and let it cool down i think that is too hot . i have dmc pipes and 138/142 jetting and 0.032 shims in each needle and it seems to run fine exept when i checked the spark plugs they were all white is that normal or should they be brown?

 

heh i dunno but one time i was riding in the country on a road that wasnt taken much so there were weeds and stuff growing on it and i didnt notice it at first but my temp. light was on and thought oh s&^% and turned off my quad, the radiator was covered with tons of seeds from the stupid weeds!!!! becareful riding in tall weeds!!!

 

Yep your running hot. Those plugs should be brown not white. White means your to lean, richen that puppy up. I'm not expect on jetting so I'll leave that for someone else. I think 185-200 is the proper running temperature for a 4 stroke, not sure though.

 

I just put a temp gauge on mine yesterday and it never got above 210.. 195 is the average..

 

Highlifter; what jets do you run? Also what's your elevation. Thanks- Carl

 

Best way to check the plugs is kill the motor at wideopen and pull the plugs for true color reading.

 

thanks everybody for your help, i took the thermostat apart then put it back in im going to gordons saturday i will see if it runs any cooler

 

I have 150/155 dynojets with 6 uni-vents in my airbox and stock needles. Im just above sea-level at about 200ft. And on the dyno its just a hair lean, but good enough for me.

 

Thanks Highlifter. I'm at 162' and run the dynojet needles and dynojet jets on the 4th clip. Just found out today that my rear slide return spring is busted that's why my back cylinder has been running weird.

 

Yea, when I put the jet kit in mine, I installed one of the springs kinda off and it ran HORRIBLE!!! I know what u mean..
