SORRY Another CCT question!

Post by Geoff »

Sorry guys I know we have done this subject to death, but write for your advise once more!

I have a small noise on the bike that sounds like a leaky exhaust, but isn't (had the exhaust checked). Its not noticeable straight away but if you listen carefully you can hear it. Like a ticking / rattle / piff, piff, piff noise.....not very loud but is definately there. Also when I put the bike in 6th gear and open the throttle it is far more noticeable. Could this be the CCT's....I am getting paranoid about this CCT issue now to the extent that it is spoiling the enjoyment of the bike. There does not seem to be any consistancy with these things failing. Comments from it sounds like a bucket full of bolts rattling about, to slight rattles, to chains jumping teeth, to failure after 4000 miles to 34000 miles. New ones being replaced only to fail again without warning after a few thousand miles. In other words this bike has a major fault of which can screw up the engine big time. Please tell me I am being paranoid here and should just forget about it and enjoy the bike. Otherewise I think I may have to sell it as you can never tell when this bike is going to cost you major bucks in repair bills. I do quite big mileage, around 610 miles a week and apart from this love the machine, but this issue is causing me big concerns.

Any feedback would be most appreciated.

Thanks guys.

IMHO CCT either breaks or works. I mean - there is no much of "deterioration", when spring breaks - it breaks.
You can easily check it by: stop engine, don't roll bike, unscrew cap bolt on CCT, small flat screwdriver into slot on turning rod (it is deep there), turn it a little bit (like 1/4 turn) to retract it a bit, then let go and see if spring turns it back to position (you see it as screwdriver turns).
If spring broken - it will not go back into positon and will stay retracted.
If that's the case - DO NOT move bike, buy new CCTs and install them follwing procedure described well on this forum.
If it turns back - you have option to change CCTs or wait, could be spring a bit "tired".
BTW: how many miles since last CCT change?

Or - you can go there and buy pair of Orient Express manual CCTs.
IMHO OEs loks better than APE CCTs...

Thanks for your help....I am new to the biking world and do not know what the CCT looks like or where to find it...does anyone have any pictures etc which could help me? Also which way do I turn it...clockwise or anticlockwise?

Thanks again

I found 2 photos - one from Gallery - my apologies for author for using his photo, I just could not find any other picture of front CCT location.

So arrows marking cap bolts on front and rear CCTs

I don't remember which way to turn...sorry...always do it "by feel"

May be somebody can tell here...

I just checked on an old one.

Turn it clockwise to reduce the tension, as Blueman said DO NOT turn it very far, only a small amount and it will turn back in opposite direction, when you reduce the pressure from your fingers on the small screwdriver if the spring has not broken,

That's not completely right as the tensioner will only return if the engine has settled with both valves fully closed (ie at TDC on the compression stroke and they will both (each cylinder) be different). if the valve (either) is open then the pressure will feedback on the chain and stop the cct expanding back once you have retracted it slightly -------- beware.

I'll vouch for that!
Thought it was a good idea first of all but then having one of the cams whip around when incorrectly changing a CCT(thought I new a short cut :oops: ) I wont be doing it that way again 8O . realised how strong those valve springs are.
Go steady.....get the timing marks lined up first.....then piss about :wink:
