I service and check the top end clearances every 5hrs and after noticing that a had no lash clearance on my inlet valves ad the clutch was a bit sad at times, I pulled the head and clutch apart to see what is going on,
I foun that the inlet valves have pounded into the head and are really only good to use as small paper weights,
The clutch: I didn't think that I abused the clutch too much when I ride but after pulling it out and finding that I have turned all the clutch steels blue, I'm starting to think otherwise,
While I was there I thought I may aswell pull the barrel and piston, both of these look ok but the piston pin is rather scored and marked where it appears to have had no oil,
Here's where the questions begin:
Has anyone else found that the valves in there head are pounding excessively into the seats? And have any idea as to why?
Will a crf450 clutch kit work in the trx700xx?
And has anyone had problems with pistons not getting proper ammounts of oil/pressure?
I am able to fix all I the above issues but thought I would find out if any one else has has similar issues,
And while I'm there I'm going to go slightly higher comp piston, stage 2 cam and a bit of porting,
I will post photos when I work out how to.
