Hello to all. As usual, I spent much time and effort trying to find answers from various places before resorting to starting a new thread on the forum. Following all the various instructions I was able to find, determined that 3 of the intake valves are too tight, with readings of .14mm, .11mm, and .13mm. All the exhaust valves were between .25mm and .28 mm. Therefore, I need to remove the intake cam in order to measure and determine the new buckets . Here is the problem. I am unable to move the cam chain tensioner for the placement of the 1/8 drill bit to release the pressure on the chain. The bike has been sitting for a couple of weeks and I have turned the engine but the tensioner only moves about 1/32 of and inch. So, how much pressure does it take to move the tensioner, I'm afraid if I use anymore pressure something is going to break. Any help or ideas are greatly appreciated. I think this might be a case of senioritis.
