HI GOOD PEOPLES
Just thought i would let you know that after breaking the adjuster and bolt the off in the HEAD :o of the cam chain adjuster :o( thirty years of rust ) to do the adjuster bolt thread fix I got a venture ratchet adjuster from the states (thanks to the info on the other great xs11 site) .after drilling and helicoiling a new thread i put the ratchet one in ;D IT WORKS GREAT :D It know longer has a faint noise (tink tink )and rattle like the chain hitting something, the other BONUS is no more oil leak from the adjuster losing rubber plugs off the end ..I WOULD RECOMMEND this great mod ..

Mate, instead of having us trolling through "the other great forums" can you put up the site address to purchase the tensioner please.
No, I haven't broken mine.
I changed the bolt and locknut a couple of years ago to a brass one. ;D Preventative maintenance.

the plunger and spring havnt been removed and theres plenty of thread to hold the bolt in
i also put a rubber o ring behind the nut, works well.

Very nice

Here's my twist to the problem of losing the plug from the end of the tensioner body.

I got a mate of mine to cut a thread down the outside of the body.

He then turned up a nut out of some brass hex bar. Inserted nylon seal inside.

Neat as you like! No more leaks, plus when doing cam chain adjustments, I take the nut off so I can check what's happening inside as well.
-
Another necessary home job/mod done well.
-
Anyone want to go halves in this pair, be about $30 each to our door.

whats wrong with your old one Brett? you can still get gasket and the little button seal from yamaha if its just a leak your worried about.
-
Is auto is good :)
-
Brett check out the UK site on this subject before you go ahead.
From my memory (what's left) there is a lot of different ideas on the subject of constant tension on the cam chain
-
The sticky on Xs11.com states there has been no problems with this mod?

Brett, I'm pretty sure I've put forward my opinion towards them in one of the UK forum's debates, but I'll put it up here as well for local content..
So you want to swap one of these

for one of these

Notice that the venture ones don't have a pad on the end of them?
This is what the Venture camchain guides look like...

The tensioner shaft end exerts its pressure on the extra part of the lower guide as per this diagram..

Something that it has been designed for.
The XS1100 camchain guides look similar to the upper guide in the photo, and have been designed to work with a plunger with a pad on the end of it.
Without the pad, all the tension from a Venture plunger will be exerted on a tiny point in the middle of the XS11's front guide run.
My second point I'd like to put forward comes from a mechanically sympathetic way of thinking.
Take your bike out for a ride on a typical very warm day and get everything nicely up to temperature. All the engine's components get hot and expand (Specifically, the camchain in this instance) It gets hot and stretches a bit.
With a standard tensioner (adjusted correctly) the slight extra length is catered for by the curve designed into the rear guide and when it cools off, everything reverts to its original size.
With an automatic adjuster, however, the chain may expand to the point that the tensioner is able to sneak another click of its ratchet while hot, but when things cool down, the tensioner will not go back to the former position, so the chain will then exert a LOT of load on the guides until everything warms up and expands again.
My final critisism is the fact that all the automatic tensioners have a lot more travel than the standard unit, so the unit will do its job in total silence, possibly way past the point where a standard unit would run out of travel with a worn chain, and still keep things quiet until a severely worn chain broke and killed your motor, so you still have to keep a check on things at regular intervals (which means removing the tensioner to measure and reset) to avoid potential disaster
I suppose if you fitted the motor with a brand new, quality camchain when you fitted the new tensioner, that would be part of the last argument against, quashed, for a while anyway
Just something for you to think about
