Dumb Question!!!

[BigBore81]

Well i was riding today and i wanted to check my plug before i went and about 3 weeks ago when i checked i thought i had it jetted perfect cause it was a tan brownish color but anyways the tempature was much warmer today and i noticed the plug was yellowich-whitish?!?!?! i have the mods listed below what are you guys running for jets? I am at a 190 main right now and a 52 pilot

Thanks

it sounds like it was running on the lean side when you went riding.

im not sure but I think warmer air actually richens the mixture because less fuel is being burned because of the warmer "air charge"

Im not sure.

I think in warmer conditions you have to lean it out. It could be the opposite though.

some one clear this up?

the colder the air, the more dense it is.. which requires more fuel..

the warmer the air, the less dense it is.. which requires leaner jetting..

It can be tough to get a good plug read from todays pump fuels..

I didn't see your lists of mods.. but I would think with a 190 MJ and a 52 pilot (??) you should be plenty on the rich side..?

How is the quad running..?

the quad runs like a champ an occasional backfire but very rare
