It'd take some major event to damage this shaft - my Monster recently snapped 4 teeth off the 6th gear at speed but the shafts are fine. The little bearing in the clutch end of the shaft could be wobbly though? Cheap and easy enough to change.
to high viscosity oil causes engine drag oil starvation and eventually wrecks the oil pump/heads and whatever else And over filling an engine dose the same with regard to drag, stressing parts in ways they are not designed to cope with!
oil starvation of certain clutch parts will damage the shaft! Eg. The thrust bearing! It has a oil ring to prevent oil from escaping but maintain lubrication of the bearing and shaft! If it gets dry it gets hot! It will bind and over time wears the bearing and the shaft! You will be able to feel damage on the inner part of the bearing with your finger! It should feel smooth like glass
Well yes, those points are true for the engine tribology however have no effect upon the the dry clutch system.
Engine drag through to much/wrong oil can stall an engine! I only mentioned it to absolutely rule it out! the dry clutch system although has no oil parts where the plates and the basket is concerned absolutely is a part of a oil system, drive and transfer power go through the clutch
I’ve no idea why you would ask me that Yes it’s definitely broken! I’m just trying to help solve a problem, if you or anyone else asks me a constructive question I can explain my thinking and why or even how to go about whatever task it may be (See why I don’t use my full stop button?) any ways, I’m not here to be drawn into argument or to hijack someone’s thread, so “up ya bum!” can we get back on topic now?
Not yet, it’s not pressing at the moment. I may have some time next week to try a couple of other options. If they don’t work I’m stripping the bike down for a deep clean and fresh paint on the engine.
Think you are correct and this will fix his problem. I know mine has never stalled again since doing the balance and tps reset years back. He's been told to try this multiple times.
I read this when I first started to look a the issue. I haven’t tried balancing as the bike idles and runs fine and the cutting out only occurs when the clutch is being used when slowing down, I may try this at some point but the fact the bike only does it when the clutch is actuated leads me to believe it’s something else.
When the bike idles and you pull in the clutch does it stall ? If not it not the clutch. My bike stalled exactly the same way you state yours does. I think you are wasting your time thinking or doing anything else before you try the balancing and tps reset fix first. You can say i told you so if it doesn't fix your issue.
Ok will give this a try, I’ve seen the home made manometer in the post above, but im assuming I can use a carb balancer instead?
Reset the TPS, first! It’s tricky and I don’t personally have the values needed for your bike! But make sure the TPS butterfly valve is completely shut and disconnected from the rear valve when resetting! then balance the vacuum and set the idle speed! This will need some going backwards and forwards to get right, and then you can set the mixture if you have a c.o, measuring tool. you might have to then look at the vacuum readings again to check that it hasn’t changed! That is literally a minor adjustment to bring the vacuum readings within spec! while you have the fairings off you might as well inspect all the clutch parts for signs of ware, it’s quick and easy to do! if neither of these work Manet look at the other side of the bike to the starter sprag/clutch bearing this may be on its way out and binding slightly! (Exactly what was wrong with my bike) and causing it to stall at idle!
Oh, and just to say, all the suggestions above are correct, and all very relevant lines of enquiry! failing all of the above I would look to the ecu!
Just to clarify @nelly , once I have the hoses connected i leave anything with tamperproof paint untouched and just adjust the air bleeds until I am seeing similar readings on the balancer gauges? asked you nelly as it was stated by yourself in an old thread Cheers
