02 400EX with white bro's slip on - what jet?

[02CR500Rex]

four wheeler is smoking a lil bit...was just wondering what jet I should be running, as I think the stocker is in there. May be rings, but may be jet. Any suggestions?

what color is the smoke? blue=oil, black=rich. As for the jet, if you have only a slip on with no other mods, try a 150 or a 152 and go from there depending on your elevation and climate

ah it's blue :( i thought it smelled like rings, but somebody mentioned I might need to jet it.

Guess it's time for the 440 kit...or maybe a 460 stroker.

oh and my elevation is around 500 above...highest hills I'll be climbing will be around 1350. Temperature varies between 65-95 this time of year...20-50 in the winter but I prolly won't be riding that much

I would go with a 416 or a 426 if you want to stay somewhat reliable. Definately time for a rebuild tho, get it done right the first time.
