> Thought this was common knowledge, geuss its just at the track.
>Under rapid deceleration, such as down shifting going into a turn, the
>tensioner can't keep up with the chain whip and alows the cam timing
>to change. If you have aftermarket cams this change in timing is
>enough to force the valves into the pistons. When the motor is
>spining higher rev's this effect is worse, so thats why they(i.e. Two
>brothers, Chafong)say to do it even with stock cams. I don't know why the
>front head doesn't have the same problem. Could it be the
>larger main jet?

> Its pretty easy to do but you need to remove the clutch cover.
>Find the clutch cover bolt that goes in by the tensioner, on top, in the
>middle of the cylinder. You need to "CAREFULLY" drill that hole out
>so it goes all the way through the case into where the chain is. Do
>not damage the treads in the hole. Be sure to catch all the shavings
>so they don't go in the case. Then tap the hole all the way through,
>8mm. You need to get an 8mm bolt thats 15mm longer than the one
>that came out. When you put it all together that bolt will stop the
>tensioner from flexing.

> Hope I explained it ok. If not, just ask me to explain it better.
