So I'm fairly certain that after 26,000 miles and two dozen trackdays.... the clutch on my CBR600 has finally shat it's last.... but I'm going to ask anyway.... there are no stupid questions, only stupid answers....

Anyone got any experience of moving to Motul 300V after years of using semisynthetic oil?

Anyone got any experience of issues after several trackdays using 300V (5th trackday, slipping on 4th)? Or switching from semi?

I'm not sure anymore in this modern age that the semi/synthetic oil thing applies these days..... but open to hear your experiences. I'm not sure the OE clutch kit was compatible with it but probably on its way out anyway, I blame old age, trackdays and the grip from the GP212s. smile

Anyone done a clutch kit on these bikes? It was a popular trackday/club race bike in its day.... does anyone know if any of the other bits will need to be replaced?

e.g. clutch plate bearing (no noise) or the inner two judder/end spring/plate things that go on the inside of the clutch kit? Or is it just a new clutch kit (springs, plates, frictions) and bosh, good to go?

Advice/feedback welcome.

I've run 300V in one of my past trackbikes. Zero issues, just remember Motul recommends changing it twice as often as a regular PAO-based synthetic (3000 miles vs 6000 miles) due to much higher esther content. If you want to save money, run 7100: that's what I switched to after a season on 300V to save money. I didn't feel the difference except in the wallet.

Regarding the clutch, 26,000 miles is about right on most older sports models. Replace plates, discs and springs and you should be all set. Springs are often still within specs when plates and discs are at service limit but it makes economic sense to change them at this stage. 99% of time you won't need anything else: unless the bike creeps forward with clutch disengaged, the lever is hard to pull in or it sounds like a bucket full of bolts being shaken you will be fine.

Thanks for that.... sounds about right. No other issues with the clutch apart from it slipping, lever has a weird springy feel to it when adjusted up but putting that down to the plates being gubbed.

A lot of guys here are recommending every four trackdays for 300V.... they also sell it... but they also race. Seems a bit much, especially at the price.

Probably go for the EBC SRK full it, springs are two bob anyway. smile

Modern oils are so advanced they are often near-new when you drain them during scheduled maintenance. Mobil 1 stuff is particularly impressive, very very long lasting, but they were the first to introduce a 60,000 mile oil for lorries, so they know a thing or two about it.
As said I could not tell the difference between 300V and 7100 except in price but there are people who swear it gives one or two extra hp and they have the dyno runs to prove it... I don't think I am fast enough to notice. Laugh

Personally I like Barnett and FCC clutches, but just avoid Adige junk and you should be fine.

Dont forget a gasket, and to soak the new plates before installing them.

The F4/F4i hasn't got a clutch cover gasket, merely engine sealant. Wink

Yes, any engine sealant will do. Just remember to scrap all traces of the old one before applying the new one.

Cheers..... gets pretty hot here in the summer so the old tube of Loctite I had in the shed has both exploded and went brick hard. Sad

Clutch in.... comes with heavy duty springs as well... can't get it to lift, not sure if it's the lifter not engaging, or if it's the cable. Something not quite right.... going to sleep on it.

Any pitfalls apart from torque settings and not connecting everything? The EBC kit doesn't appear to be exactly the same as the OEM one friction plates wise.

Most fun bits so far have been getting the oil filter (head rounded by garage!) and the casing dowels being seized....😬

Did you engage the lifter arm with the lifter piece while installing the clutch cover? It's usually done by turning the arm clockwise while installing the cover.

Hi not sure which bike you got, but when putting in the Friction and spring seat (the right way round) did you put the larger Inside Diameter plate on first, did this myself with the same outcome RollEyes

Looking at my post it doesn't sound right , what I meant was you have to put the larger inside diameter on first, I put a normal one on first which caused the same symptoms as you have RollEyes

Aye, was too tired and made that mistake myself.... swapped them about earlier, better! Still got issues with clutch drag...

The EBC heavy duty springs are 4mm longer than the new OE ones, put them in.... lots of drag.

Old springs are 0.2mm off the service limit (43.4mm, 44.7mm new) - tried two old ones, not much better, little.

Put all the old springs in, less drag.... still a bit too much but better.

Old plates are all ~3mm, Large ID friction is burnt and the adjacent steel is scored. Friction plates smell burnt.

Not sure what to do now.... doubt I'll make scruitineering in 4hrs now!

Tried adjusting it to the hilt to trial the lift.... still not great, so wasn't sure it was the issue. Was going to buy one as a spare though.... definitely wish I had now, could at least have tried it.

Hi, if you had put the wrong plate in first ,and tightened the springs up, there is a good chance that the first steel plate could be buckled , are they nice and flat Wink
