Guest Posted September 27, 2008 Share Posted September 27, 2008 I've got a Kawa ZXR 750 H1 (1989). It seems to have developed a nasty rattle which sounds like a bag of bolts coming from low down, somewhere between the mid to front end. It only happens as the revs pass though 4-5000 rpm then quietens and the sound returns again as the revs drop back down through that rev range.I've checked the cam chain and the cam adjuster and these both seem ok, I can't see any loose bits (only my head for buying this bike). Does anybody have any ideas? Your help is very much appreciated cheers.

Korben Posted September 27, 2008 Share Posted September 27, 2008 Hi MateDrop into Newbies and introduce yourself.Only thing I can think off is a lose bolt somewhere which is just resonating at those revs.Get yourself a haynes manual, a torque wrench and a socket set and work your way round the bike mate.....Has it got any performance issues when you hear the rattle?

rollazuki Posted September 27, 2008 Share Posted September 27, 2008 Check out the alternator, the drive(belt if i remember right) can over heat the bearings in the alternator, and they can rumble a lot. As its only at a certain point in the rev range, Id take a look.Rolla Quote Link to comment https://themotorbikeforum.co.uk/topic/5445-nasty-rattle-please-help/#findComment-116354 Share on other sites More sharing options...
Guest Posted September 28, 2008 Share Posted September 28, 2008 Thanks for that, I've been into Newbies and posted an entire to introduce myself, hope you enjoy.I'll certainly have a go at your suggestions as me and old man didn't think of bearings. I too thought of going round the bike looking at all the nuts and bolts on the bike and its probably a good thing I did cos there are missing bolts on the main linkage, sub frame and bits and pieces missing off the torque arm etc. The chap I bought it off said it was hes pride and joy, I would hate to see some he really loved!Many thanks Quote Link to comment https://themotorbikeforum.co.uk/topic/5445-nasty-rattle-please-help/#findComment-116407 Share on other sites More sharing options...
