Cam chain tensioner query

Post by wes »

Hi,

I want to change the clucth bracket on the cam tensioner as its bent, and I have a new tensioner only they are different.

The one on my race engine has a screw in the side of the tensioner, and my new bracket does not have this screw and the tensioner looks like its stepped with a sprung lug.
Looking at the manual, it looks like the one without the screw is from a later L4/L5 bike and is automatic, where as the one on my engine looks like its from an L2/L3 and a manual adjustment.

So..I want to put the later adjuster on the bike, as this has the better clutch bracket....is the tensioner fully automatic, or do i need to prime it or do something?

thx
Wes

ye there are two types of tensioners the newer style is the one with the bolt in the bottom of it and 2 springs one inside eachother.to fit the tensioner remove the springs and reset the tensioner down to its lowest position (theres a little lever to press and then you can press the piston back down) and then bolt the tensioner in place making sure the 'fork' goes into the tensioning blade properly, then fit the springs back in the bottom and bolt them up.then you need to turn the engine over by hand easiest way is to remove the side casing and turn it over on the timing rotor (2 revolutions of the crank so its one complete revolution of the cams) and you should here the tensioner 'click' up a couple of clicks.then bolt the casing back on and your done.
