do I have to put fluid in the trans of my 2008 trx 250ex or does the engine oil lubricate the trans and engine both? thanks.

 

Only 1 oil for engine & transmission...

 

ok thanks for the help, I thought it worked that way I just wasn't sure. what exhaust would you recommend for this atv?

 

The transmission will quickly thrash your oil....that is why it is important to run an API SG/JASO MA motorcycle oil. SG insures that it will have a descent high-pressure/anti-wear additive package, and the MA insures that it is wet clutch safe.
