Hi everyone i have built up the clutch on my YPVS using a brand new Mikita basket with new dampers brand new EBC clutch kit with plates + springs brand new lock up clutch kit etc I've staggered the steel plates every 30 degrees , everything is clean and plates steeped in motorcycle gearbox oil etc i have adjusted the YPVS clutch up matching up the lever arrow to the crankcase mark have slacked of the clutch lever adjustment , adjusted the clutch star head as it gets to a small restriction and backed it off 1/4 turn tightened the lock nut checked all is still aligned up good clutch lever BUT when i start the bike and select a gear it bogs down and stalls like i havn't pulled the clutch ?? so i removed the clutch plates and reinstalled the OLD plates and it is behaving exactly the same  i cannot see a thread on here for something similar so ANY help is really appreciated everyone please |

Does it lurch forward or just die
What ypvs loom are you using, does it have a side stand switch?

did you check that the inner hub spun/turned freely after you had tightened it up with the nut, if it doesn't turn freely, then the clutch won't work correctly and will cause drag/crashing gears as it will act like the clutch is engaged all of the time
You can over tighten that nut, it should be around 56ftlb's from memory, if you did it up with a rattle gun it could easily be too tight, also, check that your inner bearing (the big chrome one with scrolls on) is longer than the bearing in the clutch basket, especially if you have fitted a new inner bearing as if it is a smidge too long, it will also lock the clutch up, that chrome bearing should be approx 0.10mm/0.2mm longer than the inner bearing on the clutch basket to allow the basket to rotate freely against the large spacers (big round washers!)

It just die's .... it has a brand new loom from Norbo , everything works EG lights horn etc etc you might be onto something i might have missed , i have two connection's under the seat and am sure one is for the 2 stroke bottle sender and the other must be for the side stand switch ? i also have not crossed these out / bridged the connection on these , i have just left them idol.

HTH Hi Mutts , the center hub spin's freely without any problem , i can understand what you are saying , total sense ...... i'm at my wit's end with this but i think Steve on here might have something as regards the side stand switch ? i have a brand new loom from Norbo and i am nearly certain i have the connector free and not plugged under the seat , i think this needs bridged with a simple wire ??

Yes, think you need to link out the stand switch plug

I’m pretty sure Norbo only sells the f2 looms so It’s almost
certainly the side stand switch as Steve said,just join the wires together or link them

didn't see anything about a new loom, must have missed that, anyway, yeah if no side stand switch then you'll need to loop that wiring to stop it cutting out

quick update on the clutch issue i was having ...... it is now sorted thanks to Dave & Steve on here ..... Steve was correct in pointing me toward bridging out the side stand connector under the seat , did this yesterday and now have a nice solid clutch and more importantly a YPVS i can now enjoy and ride. glad i am running with the Banshee clutch case for ease to constantly pull the clutch apart otherwise i would be out a fortune on Yamaha gaskets ... LOL thank you and very much appreciated ZiG  |
