Rekless, there is not many trails here so I usually go to upper michigan to trail ride. If your in the are though, I have a could show ya some of the mx tracks. Foxx, I am not sure what the last owner ran, I found it online down in Florida. An older guy had it along with a couple other ones and did not ride it much. I do have the tools to do a compression and leak down test, I will do that as soon as I get it back together. I have the cylinder in getting replated right now, it had some scoring and the intake bridges were cracked sooooooooo as long as it`s apart......

Right on moto I will let ya know as spring nears. I'm down for any type of riding. Also final ddestination is Mellen, wi , about 1 hr from Ironwood, mi
DoldGuy:
Motovet,
Looking at that piston would have me thinking possible head gasket leak as the intake side looks washed & could also lead to detonation. Most pistons that I have seen detonation marks are on the exhaust. Be sure to lap your cylinder and head together & as Fox noted leak down test.

doldguy,
Not to sound ignorant, but when you talk about lapping to head and cylinder, wondering if their is something I don`t know about? I have always checked them with a straight edge or used fine sand paper on a good and flat piece of steel to check the head for warpage. Is this good enough or is there more I should be doing?
