CCT!? Fact or friction?
So I just had my mechanic/racing buddy friend install the APE CCT"s while I was on vacation. But he swears they didnt need replacing and questions the idea of the swap. Being a mechanic he is inherently against forum advice of all kinds. He swears that it is an old wives tale. Anyone have a REAL idea of how long before these APE CCT's need adjusting? Is it every 3-4k miles? That seems like a real inconvenience.............Just sayin.

Your mechanic friend is wrong, although I'm not saying yours needed replacing. Steadfastly not believing everything you read on a forum is as stupid as believing everything you read on a forum. A dose of common sense goes a long way. When you have a consensus about something with evidence and anecdotes to back it up, you would be foolish not to pay a little bit of attention.
I have checked my CCT's an average of once a year in the three years since I installed them. They didn't need adjustment, but I was doing other stuff and checked anyway.

OK, now we are getting somewhere. How many miles when you replaced them and since you did? I agree with the statement of believing all/none of anything. I just replaced them at the word of the brotherhood of the SH and want similar feedback.

I didn't replace the ccts just 'cause I read something on a forum. I replaced them 'cause I could hear the chain rattling around in the front cylinder.
I've only had them in for a few hundred miles. I'll adjust further if/when the damn chain starts rattling again.
Some folks say do it anyhow, but I wouldn't have bothered if I didn't have the noise.

I replaced them because of the experiences of the people whose CCTs failed. It's not "you probably should," it's "goddammit, a CCT went and it's $1500 to fix." It cost me some bucks, and it's a PITA for those who do it themselves, but bent valve/scored piston would have been worse.
The logic behind it made sense to me, too. The stockers, if/when they fail, let all tension off the chain. The manuals make that impossible.
My 2 cents.

I replaced mine @ 15,000 miles. I didn't have any issues, but it seemed like cheap insurance. I'm the 3rd owner and I didn't know how the 1st treated the bike. I was in there anyway checking the valve clearance.

I say fact, but since everyone rides there bikes a little differently I think it would be hard to get any conclusive data with mileage alone. I was at 43k miles and heard the front chain rattle, that was enough for me to park it until the apes came and I put them on. Like others have said, its not if its when, and if you let it get to when its going to cost you alot of time and money. Worst of all you wont be riding the hawk for a while.

My front failed at 18,000...didn't waste anything. I had new OEM replacements installed, am I the only one on this forum that used Honda ones? I am a body and paint guy and I like to ride the damn thing not take the gas tank off 3 times in one day!! CCT paranoia took over my life when I got on this forum... but I think I got it under control....just my 2 cents.
Cheers!

However, the problem with autos is that they can fail, while the manual ones can't that's why most folks go with manual CCTs and forget about it...RC

600f3's had the same problem. I work at a motorcycle shop and my boss was like, why fix it if its not broke. I then asked how many he did when he was at the dealership he used to work at. He had never done any VTR's, but he had never worked on a VTR, but he said that he had the F3 job down to 30-45 minutes and had built special tools to do so. He then agreed that it would be a good idea. WORD TO THE WILLING TO LISTEN,
when a cct fails on an F3, it doesn't skip, just makes noise... VTR skips and destroys!!!! He even told me that i would not need to have the bike at TDC compression, how wrong was he. But he had based this off the knowledge of Honda F3's, so there goes that negative forum view. Now, to put 0w oil in the bike, hear that it makes more power.........

i just picked my bike up tonight from honda. wouldnt you know it the mechanic had ape in his bike a 97 cbr 929 i think but any way he told me he replaced the atuo cct 3 times in 60,000 miles and the stock one go bad from spring breakage. and let the timing slip after sudden deceleration because of loss of tension or some such. so if the honda machanic says they fail eventually ill stick with the apes.

APE CCT Adjustment
An easy way to check & adjust the APE CCTs is warm up the VTR to operating temperature, rev it a few times, loosen the locknut and back out the bolt until the chain starts to rattle, then turn in the bolt until the rattling just stops, and tighten the locknut without changing the setting. Then rev a few times again to check, and readjust if necessary.

Bare in mind this procedure is for checking & adjusting the CCT AFTER they were installed properly; which entails pulling the valve covers and setting the CCT by chain tension (1/4" deflection at TDC)!

I first replaced my CCTs at 20k with the Honda OEMs. Then when Hell broke loose at 38K, I changed them with APEs. Now I sleep better at night and have a better understanding of my bike from performing all the head work from the CCT failure.

I probably will the next time I am checking the valves, but I see no reason to panic and put them in before hand. If the oem's give way before then I will join in on the bandwagon of the victims of cct failure.
