DeeG Posted October 21, 2016 Share Posted October 21, 2016 Hi there hope you're all well, hopefully someone can help me with a problem. I have got an annoying judder when I slow down and I'm riding in a lower gear. Bike runs fine when I'm in the top gear and riding but as soon as I slow down and in a lower gear there is a juddering sensation and also a rattling noise. I'm hoping someone on here has had the same problem and had a fix. Thanks Link to comment Share on other sites More sharing options...
Moderator Airhead Posted October 21, 2016 Moderator Share Posted October 21, 2016 I'll suggest you get the carb balance checked out Link to comment Share on other sites More sharing options...
DeeG Posted October 21, 2016 Author Share Posted October 21, 2016 I'm taking my bike in for a service on Friday this week, just need to use it for 3 more days to go to work about another 120 miles. It will be ok to use still. Thanks Link to comment Share on other sites More sharing options...
Moderator drewpy Posted October 21, 2016 Moderator Share Posted October 21, 2016 could be warped disks too, my FZ did that at lower speeds on light braking. got new disks and it went away Link to comment Share on other sites More sharing options...
slice Posted October 22, 2016 Share Posted October 22, 2016 I suppose it might be the chain getting worn or as Drewpy said a warped disk. To many things it could be, head stock bearing swing arm bearing worn pads loose bolts etc. Have you any idea at all as to where the noise judder is coming from? Front or rear of the bike?

DeeG Posted October 22, 2016 Author Share Posted October 22, 2016 Its very difficult to hear where it is coming from exactly, but I would say it is more from the rear of the bike. When I first start a journey it seems ok, but after ive been riding a bit this is when it starts, almost as if something has warmed up first! Wish I was a mechanic!!!!

Moderator Cynic Posted October 22, 2016 Moderator Share Posted October 22, 2016 If you use a lower gear still. When you say lower gears how are you using them. What is the rpm, speed and gear the noises start. Carb balance and plugs generally show in the lower revs with larger throttle use. I think its probably pinking.

DeeG Posted October 22, 2016 Author Share Posted October 22, 2016 Hi When I'm in say 1st and 2nd it seems to be worse and the revs are about 3 - 4000. Once I'm up to 6th gear it disappears. Thanks Link to comment Share on other sites More sharing options...
Moderator drewpy Posted October 22, 2016 Moderator Share Posted October 22, 2016 loose rear wheel? unbalanced wheel, in 6th you'll be going a lot faster than 2nd and 3rd so inertia forces could just balance it out. check all bearings including the rear sprocket carrier and rear disk Link to comment Share on other sites More sharing options...

Getting her out of that nasty 3-4k rpm range, most 600's are happiest chugging at 6-7k, 7k normally the point most non racy middleweights wake up so you have power ready to use if needed.

fabiostar Posted November 1, 2016 Share Posted November 1, 2016 my divvie done the same. only noticed it in lower gears. i changed the chain and cush rubbers and it stopped straight away.. Link to comment Share on other sites More sharing options...
slice Posted November 2, 2016 Share Posted November 2, 2016 Now that makes sense, cush rubbers, everybody forgets them till they need changing. Good thought fabiostar! Link to comment Share on other sites More sharing options...
fabiostar Posted November 7, 2016 Share Posted November 7, 2016 it seemed to solve mine. it was fine checking them with the wheel in the bike but when i pulled the wheel out they were as slack as a whores draws .. Link to comment Share on other sites More sharing options...
