Vers, please forgive me........Would it work? Pop the cover every time you change the oil and tweak it????? Is it more of a racing thing? LarryC How much braking potential comes from the front brake?

The cam chain tensioning setup for the DR650 is nothing like the Savage. The DR's CCT can be removed without opening the case, not so with the Savage.. the systems are not at all alike.

Neither the DR or Savage need a manual CCT. The DRZ400 benefits from it, but not the DR. Procycle is a good vendor but they're FOS acting like a MCCT is necessary for the DR650.

Back in the "cam chain discovery" days we all had a theoretical chain tensioning system that could replace the Suzuki system completely.

Some got built -- they worked but were cumbersome and expensive. I built an expensive spring/hydraulic system but realized that a leak could tear up my engine so I never put it in place.

I also had an "inelegant" system that I invented later, one that I did put in a motor that is still doing its job as we speak. Problem is the motor is on a pallet wrapped in plastic waiting being needed.

Verslagen won't say what his new idea is until his idea is fully cooked -- he's the silent type.

It would be easy enough to make a threaded tensioner that would replace the existing one and would mount the same way. But who would want to take the cover off to turn it a couple threads and then reseal the cover every time it was a bit loose. The current Verslavy version takes up a huge amount of slack when it is mounted using the new hole and it would be hard to put that much adjustment distance in an adjustable one that would mount to the same hardware. But one could be made with an extended hole similar to the Verslavy, you just couldn't use it until you had some accumulated chain wear and wouldn't gain much if anything over the simple Verslavy conversion.

If I were going manual I would want to be able to do it outside the case. Maybe some clever guy can figure out an easy way to do that.

Too bad they didn't just build the thing with a heavier chain that wouldn't stretch out so quick.

Which is why automatic tensioners were invented. Manual tensioners are fine if someone's the type who's always fiddling with the engine anyway.

The Savage was intended as a beginner bike that would be sold after a year or two in order to move up to a bigger bike. So there are a few things that are budget engineered. The cam chain is one of them, unfortunately.

Rather than spend the money, time and energy trying to make some kind of manual adjuster work (unless you just get off on the challenge), get a Verslavy and be good to go. Maybe get a new chain if you want to do more involved wrenching.

Or are you lookin' to bolt something on? A machinist could drill and tap a hole, put in a counterbore. And with some hardware be done. If you want a bolt on... still working on it.

I know that,... and you know that,... but does the guy who did it, know that?...
Huh

I always wondered what that plugged port was for, on the right sidecase...

Serious note... what's the downside of a bevel drive?... Do they ever wear out or need adjusting? ...
I don't mean,, ever, ever... but... it seems as solid as a gearbox... Huh
