I was a tech in a shop from '98-'04 and I can't think of one tensioner on any bike that I"ve seen completely fail. I've seen some not give proper tension and replaced a handful on F4's and F2's and even did one on my buddies XX a few weeks ago, but I've never heard or seen one actually bust completely. Then I come on this forun and it seems every other thread is CCT related and lots are busting. Expecting the guys at the dealerships to know every single problem about every single bike is like asking the general subscriber to this forum questions about a Busa. Some may know but most wont.

I think exhaust valves are a little more susceptible just b/c they're bigger. And I was in no way trying to knock dealers... you're right, most have to handle Shadows from the 80's, two stroke CRF's from the 90's, fuel injection 1000rr's from 2012 and everything in between. I was just sayin that you'll often save much troubleshooting and $ coming here first.

that's true...
what bugged me was that they were like...ohhh...you gotta take what those forums guys say with a grain of salt...(we're the pros...kinda thing)...they absolutely told me NOT to mess with the stock units...that's what got to me...
I can just imagine what a teardown like this would cost a non-mechanic...

That's something worth while looking into I think, longer bridge may help prevent this failure. The only thing is, I'm not sure how much cost effective it will be compared with just replacing to manual CCT's...

Most people who price that one out end up looking at a used motor to swap in as a financially valid alternative.

Yeah I know what you mean. It's kind of a double edged sword. On one hand you’ve got the techs that for the most part know what they are doing and generally know the proper procedures for things. On the other hand you’ve got a lot of hack job’s online doing shadetree mechanics in their backyard and posting it all over the internet, which then by many’s standards must be true because they read it online. Then you’ve got the flip side of the dealership techs may not have a lot of specific knowledge on a specific model that’s not overly popular in their area and they don’t see much, and you’ve got forums like this where for the most part the information you get is pretty good because there are a lot of guys all riding the same bike and most all the issues that the bikes have have come up with someone on the forum so they’re much better documented. It’s easy to see how the forum guys hate the shop guys and vice versa! LOL!

With my CCT coming out and bending the front two intake valves I’ve got about $250 into all the repairs from parts to having the guides replaced and valve seats re-cut. But I did all the labor. I’m guessing you’d probably be paying $400-$500 in labor depending on what your local shop rates are so you’d probably be pretty close to the $750 range for the repair if you couldn’t do it yourself!
