gazzaecowarrior Posted December 12, 2010 Report Share Posted December 12, 2010 Hi there In a trial today and was blasting up a graded hill climb when all power just faded. Bike stopped. Couldn't be kicked over. There appears to be a spark at the plug. Fuel is in the tank as I had just refilled for the 3rd lap. Managed to get the bike going but it would only idle on full throttle. It was enough for me to limp back to the van with me pushing it. What do people reckon this could be ? It's dark so i haven't had the chance to give it a once over yet. When it died on the hillclimb it was just like my stator failing on my Rev3 but i didn't think the rev4 had these problems. Would appreciate your advice. Carb or electrics ?

godzilla Posted December 12, 2010 Report Share Posted December 12, 2010 Is it an 07 or o8 bike? is the airbox clean when did you clean the carb last? Quote Link to comment Share on other sites More sharing options...
gazzaecowarrior Posted December 12, 2010 Author Report Share Posted December 12, 2010 Is it an 07 or o8 bike? is the airbox clean when did you clean the carb last? it's an 08. No I haven't cleaned the carb for a while. Perhaps that should be my first port of call. I would expect it to splutter with carb problems. It just died in seconds as if someone had turned the engine off. Airbox is cleaned every outing Quote Link to comment Share on other sites More sharing options...
benbeta23 Posted December 12, 2010 Report Share Posted December 12, 2010 (edited) If I was you, I'd start by taking the carb apart & look for crap inside it, Give it a good clean out! This is very unlike a Rev4! There usually Bomb Proof. Edited December 12, 2010 by BenBeta23 Quote Link to comment Share on other sites More sharing options...
mobbster Posted December 12, 2010 Report Share Posted December 12, 2010 Hi Sounds like you could have water in the carb float bowl at full revs the bike will die as soon as it sucks up a gulp of water... (this has happend to a few of use while out riding and we soon got it sorted with a 17mm spanner. I would crack the bottom float bowl nut off and you will probably see water in the nut. What you explained does sound like the water problem. Only other thing is are you still using the std beta kill switch ? Cheers Quote Link to comment Share on other sites More sharing options...

I hope it is the carb as it is a cheap and easy fix. I have changed the killswitch for a yamaha one. Quote Link to comment Share on other sites More sharing options...
sparky Posted December 12, 2010 Report Share Posted December 12, 2010 Had same thing happened on my 08 rev 4 when i had it. plug looked like it was sparking but it was all over the place. It had gone pop with revving it. Try a new plug in first thats all that was wrong with mine. Quote Link to comment Share on other sites More sharing options...
