Today's task was storing the YPVS for winter so had vac bag ready but decided a last blast was needed.
Clutch always slipped for the first couple of times going on the power till it was up to full temp but was fine after that. Ran bloody good with the nice cool air and had no problem going in to the power but if it hit a bump around 8k the revs would soar before coming back down after a couple of seconds gripping with a bump so job next year is a clutch upgrade.
Any advice? Whats everybody else using?
Got HD srings but wondered about plates

Stock springs.. Ferodo 'race' frictions; 7(:-) and Oem plates from an FZ600 (actually same as those in many if not most of Yama's Bigger Bikes of yesteryear)
Unlikely to slip.

3 x TZ750 springs, XS750 EBC plates with rubber rings removed, don't slip, lasted two seasons of racing :-)
If your clutch basket has deep ridges on the tangs it can cause slipping problems as the plates grab

Basket was mint from a very low mile 250 so no ridges but do have a mitaka basket to go on, just being lazy as it wasn't broke type thing. It does still have the rubbers but they were on the bin list anyway. Just used what came out of the last tuned motor as it was known good, just doesn't cope with the stroked motor now  Bare - may try the standard spring route to see if it copes, easy to change with the clutch window. It's in it's bag now any way but will order the parts so I have it all ready for spring. Cheers for the advice Steve |

So do the steel plates remain the same as standard but he other plates are wider so take up the room where the rubber dampers went ? Steel plates will remain the same. Plates are wider so more surface area. Just wanted to know what plates others are using. Had heard the FZ600 plate route before bare mentioned it and have know checked fleabay and the EBC kits fot XS and FZ have different part numbers so back not knowing which to buy. Steve |

Steve uprated my clutch with the wider plates as mentioned, they were the XS 750 ones but again as stated they are used in quite a few FZ-XS models.
The part no on my box is EBC Heavy duty CK2279. Google it and see!
Hope this helps, Mark.

Clutch isn't much heavier with the TZ springs, certainly not enough for the other people who have ridden it to comment. The steels are stock Yamaha RD, the o rings go in the bin. I use Silkolene light gear oil normally, but it didn't slip on the 4 stroke 10/40 I had to use in an emergency after a rebuild. Might not need the springs with the bigger plates but I've never tried it. The bike puts out 60 plus hp,and my starts are atrocious, so the clutch gets a good work out!

My clutch is heavy hence me thinking it already has hd springs, probably going to fit the R6 cable at same time to see if it helps. Reckon mine is over 75 hp now so hopefully will handle it. Steve |
