Faults:

I regularly change the oil and filter, lube the chain, etc.

Has needed nothing in the time that I have owned it.

General Comments:

I bought this bike used with a 440 bore-out kit.

I use this bike on and off road.

It has insane power.

This bike is extremely reliable and gets great gas mileage. I get up to 55mpg on the road.

The bike is a beast off-road, and goes through anything.

Can be hard to kick-start due to the bore-out.
