hmm, interesting fact I didnt know before...from the APE web site
IMPORTANT: WHEN REPLACING ANY HYDRAULIC OEM TENSIONER WITH A MANUAL TENSIONER, IT IS IMPORTANT TO BLOCK OFF THE OIL PASSAGE THAT SUPPLIED THE OEM TENSIONER. FAILURE TO DO SO COULD RESULT IN A LOW OIL PRESSURE SITUATION.




I couldnt find an exact spec for the Yami's, you might have to call them if the instructions dont say. I am guessing its going to be about a 1/4 " of slack required though. Best bet is to call them and see what they have to say, they will probably have some advice for you on the best way to block that oil passage too.

- jb weld to block off
- it says 1/4 " back off once tight. now tight by hand or with a tool, thats what i dont know. how much pressure should i put before i back it off 1/4 "

No idea. My guess, some will go back, some wont, and some will split there time.
i think im going to split my self :lol
i like the smilies in this forum. :rofl

Dont tighten down with a tool!!...just snug it up to the chain, probably need a wrench on there, but when you feel it getting some pressure that should be good. JB weld scares me in an oil passage like that but if thats what they say then it probably works. Just make sure its as clean as possible.

yep, Youll know when its tight, probably best if you have the valve cover off so you can check the chain, that way you know when its tight and your not stretching it.

The valve cover should come off without pulling the motor. But either way. You should be able to do it by feel too.

I have the ape on my 99 r1 and it's a great tensioner. Easy to adjust and you don't have to worry about it failing like an auto tensioner. You'll love it.
sweet, was it that hard to adjust that first time or who did you do it.

No, the true benefit of a manual tensioner is that it maintains a consistent tension on the cam chain under both engine accel and decel giving a more consistent cam timing. And in the case of High compression pistons and aftermarket cams, helps limit the possibility of the pistons hitting the valves due to said cam timing variability.

yes, but the gsxr's fail often and that's why most install them...not have to replace it again and no worries of it failing. With yamah's i don't think it's a huge issues, but with gsxr's the cam chain tensioner fails more often...the ape is nice as you have no worries. Also if you're already in that area, why not...
