Hi all, having a nightmare with my clutch cable adjustment. Had it all apart recently while doing different jobs, mainly replacing the front sprocket nut.  Come to put it back together, and i can’t seem to get it right, i think i have played too much with the adjuster on the crankcase. Each time I think i’ve got it right , I go for a ride and under hard acceleration it ‘slips’ which i assume is clutch slip due to dodgy cable adjustment.


Yet if I try slacken the cable at the crankcase, it becomes incredibly free / soft, even with the lever adjuster tightened.


How do i get the adjustment at the engine side right? And what’s causing my clutch slip? Thanks in advance

Thanks for the info,will measure the thread all along when I'm swapping the nuts early next week.

I fixed mine by cutting a slot on the shaft and drilled a hole at the end to put a bolt and washer in it. I put what I did in the downloads section, but it seems to be missing.File also explains what else to do to prevent it falling off and stranding you if the fix failsDid this at 71000miles and now 99600miles and had 2 sprocket changes since and thankfully still good.
Message me your email address and I will send the file I put in the downloads to you.

Annual bikers day trip to Margate organised by the Ace Cafe. I’ll be down there with my red FZ1 and manning the MAG stand.  Its only a 30min ride down the M1 and around the A406.

For interest when Yamaha first recognised the sprocket nut problem they told dealers if the thread outside diameter was 17.50 m.m. or greater it was o.k. If less than 17.5 m.m. it needed replacing. The few I've measured in the past were always in the 17.85 to 17.86 range.
