Jet Question

[Ryan300exRider]

I have a 300ex with a Yosh Slip On... Will it hurt my quad if i run it with a K&N air filter but no jets....?

no jets???:huh

I think he means no jetting changes.

Should be ok since most quads are over jetted from the factory but keep in mind it will run leaner in the cold air.

Note that you should keep an eye and ear out so for sign of running lean so you dont cook anything.
