devilchef Posted February 26, 2014 Share Posted February 26, 2014 Hi all Bikers,I noticed the other day when I was in the middle of a downpour the bike really started to judder, not sure if water got somewhere but probably. I would like to try and find out where the water has got in and what to do about it, would anyone have any good suggestions? I should say that i am not very technically minded when it comes to bike so nothing too technical please...i know how to start it and thats about it lol.The bike has also has the same problem after all that rain we had....it was covered outside (don't have a garage) but when it had cleared up a bit, i took it out and the juddering was there for a while.Cheers all for your expertise. 1994 Suzuki GSXF 600.

Stu Posted February 26, 2014 Share Posted February 26, 2014 probably one of the spark plug caps not sealing properly Quote Link to comment Share on other sites More sharing options...
Tango Posted February 26, 2014 Share Posted February 26, 2014 Or the wet causing one of the HT leads to track down to ground a bit......have a spray round the coils and HT leads with a little bit of WD40...... Quote Link to comment Share on other sites More sharing options...

Now on a car that wouldnt be a problem but on a bike, i am useless, i haven't taken the fairing off too see though, does my bike have a carb? could that be a possibility as well?

Tango Posted February 26, 2014 Share Posted February 26, 2014 I'm pretty sure that your bike is carbed......but my money would be on problems with damp in the HT leads or coils..... I had a Yamaha XS1100 years ago that was a right pain after it had been washed.....would only run on 2 cylinders until the engine got hot enough to clear the water from all 4 HT leads/Plug caps.....then it would come back onto 4 cylinders....sometimes quite violently....as a mate's girlfriend found out once when she was riding pillion on my bike.....

Stu Posted February 26, 2014 Share Posted February 26, 2014 yes your bike is carbed but I doubt that is the problem it sounds electrical and when its damp its missfiring the plug leads are right on top of the motor and go deep down in to the head you have rubber washers around the plug caps to keep water out also some bikes have a weep hole on each port to allow water to drain out if yours has these make sure they are clear WD40 is good to see if it is the problem but a bit of electrical grease in fact normal grease will be better around the caps dont use vaseline as some contain petroleum which will eat away at the rubber eventually Quote Link to comment Share on other sites More sharing options...

eastanglianbiker Posted March 5, 2014 Share Posted March 5, 2014 the juddering when running will be it misfiring unless ur chain is slapping about very loose or its when you are braking but from what you said everyone has given right advice i think Quote Link to comment Share on other sites More sharing options...
