Question for APE Manual CCT Users
« on: June 25, 2015, 12:02:13 pm »
Good morning.

When I had my bike appart to check valve clearances I installed an APE manual cam chain tensioner (disliking the rattle at start-up).  I followed the instructions that were posted online before putting all the engine covers back on the bike and then did a final adjustment after starting the bike.  Rode it a couple days to work and then headed to the National. 

Aftera a couple of spirited sections of road where I was using a lower gear/higher RPM I notice more engine noise.  Once reaching Cortez I tightened the adjuster and the noise calmed but did not completely go away (I was concerned about possibly overtightening).  Once home I rode the bike to work without ear plugs one morning and noticed it was still a little clattery.  Nothing serious...just more than it was with the OEM tensioner. 

Thankfully I can get to the tensioner by just removing some of the fairing fasteners so it is not difficult to get to and adjust, but before I go back in to tighten it further I wanted to see what other APE users experiences have been.

Thanks for any feedback!

Have you read through the installation procedure on APE's site about taking the slack out of the slack side of the chain by constant pressure through putting the bike in gear and trying to roll the rear tire forward and holding it there, then run the adjuster in per the instruction sheet.

Here another good write up:  http://www.zx14ninjaforum.com/messages.cfm?threadid=9CFD17D8-1372-66AE-3B0D2BD6B6297697

The best thing to do is to tighten the tensioner finger tight with your fingers, and then tighten the jam nut. Be sure to use 2 wrenches, so that when you tighten the jam nut it does not turn the tensioner in further. As long as you use your fingers you can not overtighten it. I have APE tensioners on all of my bikes, and never have any cam chain noise. Mike.

Thanks Cory and Mike.

Cory:  Thanks for the input.  I did not receive paper instructions with the CCT but did read through the information on the APE site and followed them to the point of the rear tire/in-gear step.  I had the bike on the lift and it would not have been convenient to take it down to perform that step.  I did find the post on the ZX14 site which followed the APE info (again minus the in-gear step).  I did notice the noise is more noticeable on light throttle/decel...

Mike:  Thanks for reply and the suggestion using finger pressure.  Although I did this initially, I will have to get back in there, loosen the lock nut, and recheck the tension. 

Based on your responses, I suspect I still do not have enough tension against the chain and with the riding and some higher RPM fun, the lack of tension is making itself known.  I will report back after I get a chance to dig into it. 

I finally got a chance to wash the bike the other night (roughly 4k miles of bugs and nastiness) and clearly I should have tried to wash it in Cortez as there is some residual yuck on the surface of the paint I need to get the polish out to remove.  Until I get a chance to address both the paint and the CCT....I will be riding the M900.

Thanks again.

I have it on good authority (George) that a clean bike is not as fast.

I have one, I back it out till the rattle is heard and then slowly turn it in till the rattle stops. Some say to turn it in (tighten) till you hear squealing sounds! I tried both ways and I like the just tight enough to stop the rattle. I have had to adjust it twice in the last 30K miles, just a wee bit tighter each time and I mean not even an 1/4 of a turn. This is on a 2006 ZX14 BTW. When my C14 starts to rattle I will install the APE.

Quick update:

NSWT:  I suspect if someone were to secretly do a full detail on mentioned riders bike....he would be just as fast. :-)

gpd323: Thanks for the reply and knowing there will be some indication that it has been overtightened is comforting.  I would agree that tightening to that level would not likely be good though.

All:  Work and life demands finally cut me a break last evening and I adjusted the tensioner.  Just a small amount of additional tightening took care of the remaining clatter.  Not riding the ZG1400 right now (still commuting on the M900 and ZX900) but hopefully it remains quiet after some miles.

Thanks again for the responses!  Very helpful!
