Cam chain Slap - FSE 400
I have just bought a 2003 400FSE and the rattle/slap from the cam chain is nuts! I took the tensioner off last week, reset it and reinstalled it but it is just as bad as it was.
The engine has done approx. 300 enduro hours - Is it common/normal for these engines to have this or is this pointing to an overly stretched cam chain? I have nothing to benchmark it against. Thanks Luke

You could take the head cover off and physically check how tight the chain is. A worn chain or faulty ACCT may be the problem. You could also install a MCCT (manual cam chain tensioner). I used a DRZ one from ThumperTalk. If it's slapping as much as you say, it could slip a cog and cause you some real problems.

Does anyone know the service limit for stretch like other bikes? max. distance between X number of links?
I took the cover off when I removed the tensioner to ensure that when I removed it , it didn't slip. It seemed tight enough but without something to measure that's pretty subjective! It's just seems noisy when I'm on the bike. I bought an APE MCCT from a user on here but it doesn't fit. Could you point me to a link for the one off Thumpertalk? Thanks Luke

Hope this helps. It's a nice product and they pay the freight on it. Also, there is much info(posts) on the MCCT on the site(DRZ forum), I would advise reading some of it as well. Tony |

Thanks Tony
I will check out some threads. I already have a mcct setup on my 675, so know the process. Just to confirm - The DRZ tensioner a straight fit? I'm in New Zealand you see, so ordering wrong parts is a bit of a hassle as I have already found out!

I am going to ask a silly one... but thought I should...
You sure it is the cam chain and not just the drive chain? Mine gets noisy when loose... I even have it a little tight just to stop the noise.

Not sure that's a good idea. You'll be putting stress on the final drive shaft and bearings. I always find the recommended settings too tight already especially when wet.

It has actually got better since I reset the tensioner, but I'm keeping an eye on it and will probably swap it out for a manual one when I get hold of one.

I replaced the cam chain on my fse 400. They are prone to wear and aren't too impossible to change if you are mechanically minded. It would also be a good time to adjust your valve clearances while you have it apart.

Tony, You used a DRZ, TT MCCT on a GasGas 450? I'd like to try one on my 450 Quad. Mike.
