FS570 Manual Cam chain tensioner install advice?

Hello there,

I recently bought a new DJH tensioner for my FS570, before fitting it i decided to called my dealer mechanic and he told me to not remove the factory tensioner without the engine being at TDC or the chain could jump causing the cam timing to go out. I questioned him on this and he said he had personally seen this happen on a 390 engine he was working with..although on DJHs site the fitment instructions claim that for the XC 4 engine's, Crank/Cam position is not critical when releasing tension from the chain.

DJHCycleSport.com XC4 Installation Instructions

Who is right? is this mechanic an idiot? or are the instructions on DJHs site incorrect?

Cheers.

I wouldn't ever say he's an idiot, but I do think your mechanic is being way too cautious. I've done Dirt Tricks (not DJH) cam chain tensioners on a couple of 70 degree engines and I can't see any way the chain could jump unless you deliberately did it yourself. Just use common sense, follow the manufacturer's instructions, and you will be fine.

No way you can lift the chain off without loosening the cam.

That's what i thought..anyway i have fitted the tensioner and for a few weeks the bike was running a lot better, but as the weather temps have started to drop its been harder to start when cold which is sorta why i started this thread because the only change Ive made to the bike is adding the manual tensioner.

I might up the idle speed tomorrow and if that doesn't work maybe change the spark plug which i haven't touched in over 30 hours. The bike has always started fairly easily so im not sure what the problem is yet.

It COULD happen if your cam chain is too stretched. That when the engine isn't at TDC, the valve springs would try to push the cam into tdc, if you then loose cam chain tensioner, it COULD get loose enough to jump a gear because the rest of the engine doesn't rotate (if it's in gear for example).

But if that's the case you would have to change your cam chain anyway.

Okay, well i have nearly 4 threads showing on the tensioner adjuster nut which according to most people on here who have them fitted is about normal? so im not thinking that the chain is too badly stretched for that to happen.

If you haven't done it yet check the cam timing at lest that should tell if it's off a lot or a little. Chain stretch bad sprockets , guides thing to look at.

I fitted one to and I am not to sure mine is installed 100% correctly according to the instructions they say turn with your fingers until you feel resistance and than a half or 3/4 extra turn...
If I install it like this the engine vibrates a lot...
Some say they adjust it by sound but I couldn't hear any chain clattering only see the engine is shaking so I turned in untill the bike was shaking less maybe it's to tight now I also have 4 threads showing and it's a new camchain to...

I ended up removing the top cover and checking with my fingers how the cam chain with guide felt. I ended up close to the recommended setting but I was sure it was ok.
