1992 KX500 Snow bike engine for Brent

Post by Sandblaster » Fri Dec 09, 2016 10:05 pm

Brents 1992 KX500 engine needs a bit of work before it's ready for his snow bike.
Starting with the cylinder.. It has been ported by Eric Gore.
This cylinder porting would be great for a trail bike but not so good for a Snow bike..

When you see stuff like this on a bike it makes you a bit nervous on what you will find..

At first glance the transmission didn't look to bad... excluding the milky oil of course..

This one is chipped which is why there was some metal shavings in the bottom of the cases..
