Rattly engine, please help

Hi, just recently my 1999 SV 650S has developed a tapping on idle, sounds a little like when the tappets have gone on a car. Does anybody know what this is??? Or is it pretty normal??? And how to fix if it is possible??? Cheers

Cam chain rattle?

Definately the cam chain the ajusters are prone to fail as the rear one on my 1999 curvey did!!!!!!!!!!!!

Hi, if it is the cam chain adjusters.... how easy is it to fix?? how much?? anybody know?? Cheers

3 choices
1. Do nothing and live with it - its part of the sound of an SV - just like Honda transmissions whine!
2. Spend nothing, lob it in 2nd (with the engine off) and pull the bike back 2 or 3 inches (this stops the rattle for a few days)
3. Spend a small fortune and change the cam chain adjusters

There is this thread with pics and instructions on how to tighten.

I tried it yesterday though and couldn't see any way of tightening it after I took the bolt out - have I got the right one? Is fiddly btw, frame gets in the way.

earplugs usually sorts out the odd rattle.

put bike in 2nd and pull back?

you mean roll the bike backwards i take it ? lol just making sure.


and what if you do it more than a few inches?


my bike is getting realy loud with the clicking by the way.

Yup, it's a fiddle. Best tool for it is a side-armed ratchet screwdriver, Maplin do one that's perfect, with a wee thumbwheel on it. Doesn't tighten the tensioner though, it actually releases it- then it retightens to the right position automatically.
