Actually, looking at:
http://www.cmsnl.com/yamaha-xs1100e-...list/A-11.html and comparing it to:
http://cgi.ebay.co.uk/ws/eBayISAPI.d...=STRK:MEWAX:IT
there's quite a difference between the end of the plunger on the standard XS1100 and the plunger from a VMax. The rubber block at the end of the standard plunger means that the force of the 'push' is dissipated over the entire width of the cam chain tensioner blade but it seems to me that the Vmax one is nowhere near as wide at the point of contact with the blade. Could this damage the blade or cause it to wear? I'm sure the blade will get a bit of hammer from the chain whizzing round all the time. Or am I missing something or getting it wrong here?XS1100F 1980 European model. Standard. Dyna coils. Iridium plugs. XS750 final drive (sometimes). Micron fork brace. Progressive front springs.

Ivan has a venturer tensioner installed that also has a plain steel plunger. He actually took the motor apart after 4k miles or so, and inspected the cam chain guide. There was a little bit of rubbing on it, but nothing that could remotely be called damage. I don't know about the VMax tensioners, but from the pictures it looks an awful lot like the venturer variety.I think I have a loose screw behind the handlebars.

I don't think the actual contact patch would really be all different size wise. Maybe 1/8 inch square total (just a rough guess from seeing them). Cause as the chain wares the plunger is going to be touching the blade slightly differently as it basically rolls across the face of the plunger.Nathan

I wouldn't worry about a little metal-on-chain-guide contact. For starters there's two parts to the chain guide on the tensioner side that provides a little buffer between the guide and the plunger. And if you think about it, the other side of the guide has constant metal contact - the chain rubs on it all the time, and at significantly higher speeds than the plunger is ever going to generate. Probably why it's made out of teflon.

The vmax and venturer have the same part number. No diffrence what so ever. Also looking at the vmax guides and venturer they look the same as the xs. So if it was such a big deal then all the maxes would have problems." She'll make point five past lightspeed. She may not look like much, but she's got it where it counts, kid. I've made a lot of special modifications myself. "

I had an FJ1100 tensioner on mine for a while. It goes in deeper than the stock unit, and the plunger won't hit the chain guide squarely. It puts a lot of tension on the chain, the holes don't line up and need to be modified to mount it, and I could never get the one I've got to quit leaking. I s-canned it and went with a venture tensioner.I think I have a loose screw behind the handlebars.

Hopefully, both OEM and Vmax will push at similar pressures?XS1100F 1980 European model. Standard. Dyna coils. Iridium plugs. XS750 final drive (sometimes). Micron fork brace.

They do. I have them both and I had them off the bike playing with them. The vmax one in a little longer. And yes it doesn't have the rubber but that doesn't mattter. Look how much trq and hp the vmax has it doesn't wear cam chains any quicker I am sure. its not like the cam is rolling around on the tensioner itself. Also I had taken the oem one off several times to fix the leak. It always weaped just a tad. The vmax one does not." She'll make point five past lightspeed.

I have a line on two venture cam chain tensioners for $25.00 USD each plus shipping. it is a package deal.
Does any want one of these for $25.00 plus shipping?

I think I'll buy a VMax assembly and compare the pressure that the plungers push at.I think I have a loose screw behind the handlebars.
