hi all
just thought i'd share an email i received today from revolution uk regarding CCT's.
Hi
Was recommended you guys from vtr1000.org.
Any chance of some advice?
No problem.
Recently bought an 02 vtr (later model) with 4000 miles.
I’ve done a load of research on the net and one problem that seems everywhere is CCT’s.
Do you think I should worry about these tensioners yet?
There is no point in worrying. I know CCTs that have done more than 40k miles and others that failed under 100!!
You are extremely unlucky if a failing tensioner damages the bike. I think that the general opinion is that damage occurs in less than 1% of CCT failures
People talk of putting APE manuals on, should I consider it?
Although I use manual tensions on all our race bikes nowadays, I do not recommend them for general street work. This because they are set up "by ear" and not many people have the expertise to do this. They also need regular adjustment and a street rider does not want this - it is different for a race team where the engines are constantly being rebuilt. eg the BSB S/Sport race bike that I support has its engine completely rebuilt after every 7 hours of running. We have three engines as well !!
After having a 600 bandit the vtr feels and sounds a bit “lumpy†anyway,
Run the tick-over at 1100rpm. It will always feel lumpy to an inclined four cylinder. If this is occurs at low revs it may benefit from having the carbs balanced.
but my main question is, would I definitely hear a potential problem as I’m not sure what a heathly tensioner sounds like anyway.
There are no partial CCT failures they are either perfect or have failed!!! There is no mistaking the noise of a CCT failure!!!
Hope this helps
Cheers

.Mine did both exhaust valves on the front cylinder not a small bill either!
Timbo, when you get it done can you find out roughly how often they need adjustment? Or is it just listen to the engine and tweak by ear?Timbo wrote:The man at revolution is fitting my APE CCTs in the next few weeks. No idea how long original ones been on so i am changing just in case.

Rogers a good guy to have a crack with full of knowledge
when I was there he had a rc30 motor in bits and was telling me the tail of how the owner had forgotten it had a race style gear box i.e. gears go down instead of up. came out of a corner opened it up to the rev limiter then changed up bang no more engine con rod tried to escape from the crank case piston had carried on in to the head and pushed the valves through the head in to the water jacket end result very expensive fishing weight

The guy at Debben Racing (who sold me the APEs) said adjust every oil change (so 8,000 miles) would be sufficient and that the precise tension wasn't too crucial, enough so that the cam chain didn't lash about at any point of the revolution, which is what I did, with no problems so far, although I only did about 3000 miles onthe Storm last year.
I think once you have had one go (with considerable expense) the peace of mind aspect is really worth it.

Two bikes, still only four cylinders!
