XT600 Engine Rebuild
Hello everyone...been lurking around here for a while and I figure it was about time I posted an intro and ask a few questions.
After researching the XT600 I decided I needed to get one. I ended up picking up a 1990 XT600 with 6,000 miles for $800.
Here it is when I bought it...
Enjoyed it...road around town, climbed some local hills but not wanting to take it too far out of town until I get a couple issues resolved.
As it sits today...plastidip painted it/protaper bars and grips/mirrors that are the worst I have ever had. Need the stock ones back, broke one while offroading.
The main reason I am posting is to gather some information on potential engine rebuild ahead of me. After putting about 1,000 miles on it so far I have been noticing a pretty persistent clank,clank,clank coming from what appears to be either the cylinder head or the main bore itself and also occasional white smoke out of the tailpipe. I have done a compression check and got readings between 100-110 psi, leading me to believe maybe the rings could be worn. So I will be pulling the head off pretty soon to check how the bore is looking and also the condition of the head/valves. I also pulled the bolt off of the oil filter cover and had plenty of oil coming out so I am assuming it is getting plenty of oil.
1) When building the XT600 engine have the aftermarket gasket kits been of good quality or is OEM the best route?
2) How difficult is it to check and replace the cam chain if necessary? Is a special tool needed?
3) Should the crank woodruff keys be replaced? And is there one on each side of the crank? Any special tools?
Any other tips for rebuilding the XT engine would be appreciated!
