Hi, i just saw these in another forum
are they better than the simple long bolt assmbly

RWhisen

Those are reworked OEM CCTs that have been converted to manual.

Depending on how they're made, the most likely the same, they just use the oem plunger instead of a carriage bolt.

And you can make them out of the OEM pieces for a few bucks.

Finaly they dont work well.I did those in same way.In the halfe summer I got some tickering noise in the rear cilinder.First I was thinking it was valve noise but no,it was a cam chain loosening and broken rubber piece inthe top of the tensioner.So figure it out are they good or not.

He was comparing them to the other version of the home made ccts, where a long carriage bolt is used instead of the OE plunger.

I would recommend using just a carriage bolt, less pieces means less pieces that can fail.

chemomche

yep, that was my question

less part - less fail
but isn`t it important the part that contacts the chain slider?
isn`t this cap on the end made with some "special" shape or material?

Well, it is a specific shape, and in theory would provide a slightly better support than the carriage bolt (a wide surface rather than the rounded end of the bolt). It's some form of metal, so I doubt the material is anything special. That being said, if it was really important, all of the racers and companies that make MCCT's would figure out a way to shape their bolts as well. If you look at where the forces are being applied, it probably makes such little difference that it doesn't matter.

I've never read about one failing correlated to the shape of the MCCT at all. And would be much more skeptical of having to deal with more pieces...
