Urban legend about synthetic oil.

[Rkt-Rch]

Really !!! Been thier done that !! On various different bikes.. Lesson learned.. Clutch disc's replaced...

Whatever.... Use whatever.. It's not bike

I to had clutch slipage issues when I first got her on the road a few years ago, so last year I picked up some EBC disc's off of E-bay for GREAT price. Like a idiot I did not replace the 4 springs, I mesured them and they speced out . Installed the new fibers useing Valvoline 4 stroke oil and thought all was fine, It did ride much better for the rest of the season. Then this year I took it out and noticed when I started to ride it pretty hard it was slipping on WOT... Crap... Bought 4 new EBC springs and WOW what a difference a complete different bike!

Now when I shift hard the bike responds, I wish I had these installed when I took it to the drag strip last year I think I might have given those 1100's a race LOL or at least it would have helped my ET's.

DON'T Run synthetic oils... Remember you have a WET clutch and yes the oil works great for the motor but does wonders on the disc's also.

Replace the springs and you will be mostlikely good to go. I didn't even notice a difference in my clutch lever pull in feel.

Well I did replace all my springs of which there are six, and they are genuine suzuki from my Suzuki dealer. I have just bought a set of EBC fibre plates off EBAY with new springs as well. EBC say these springs are 10% stronger than standard.

Just shim the springs with washers. Start with around .060 and go from there. If you still have clutch slip then add washers.
Any groves from clutch plates in the basket or hub? If so they can make a clutch slip.

Graham there are no grooves in any of the clutch parts. All in perfectly good condition. Shimming is a good solution. I got the EBC springs for $8.95 a set so I will probably try them first.

That will work.

EBC claims a 10% spring rate increase but get ready for a noticeable increase in hand effort needed. Regarding shimming the springs, that will work up to a point but the springs will coil bind before you get a whole lot of shims in there.

Just use three of the EBC springs and three of your stockers first...worked for me...

lol i need two hands to pull in my clutch lever with 2 washers on each spring

Hummm I just put 4 new EBC clutch springs in mine and didn't really notice a difference, I just saw some valvoline full synthetic 4 stroke oil for bikes I might try but at 8.95 a quart is it really worth it? And YES it does say it is compatiable with wet clutches... sorry must have been a few years back when I tried it.

Shell Rotella synthetic is rated for use with wet clutches. About $20/gallon at Walmart.

I always use half stock and half EBC. Some increased effort but not too much.

Don't forget the steels do wear as well so even with brand new fibers you may have some tolerance in the system.

I agree that old plates can age harden or something but if you remove, clean then scuff them with emery paper, clean, soak in oil and Re-fit it seems to sort them out. I think the outer surface glazes and you need to break through that.

I have just bought a set of EBC fibre plates off EBAY with new springs as well. EBC say these springs are 10% stronger than standard.

Well my new EBC clutch plates arrived today, I also received a new set of clutch springs from them which was only $8.99 extra and no addition to the freight. I reckon these will be a good backup in case my Suzuki springs don't do the job. Although I don't see why they wouldn't as they were bought new and have only done 300 miles.

The specs for new plate fibre thickness given by Suzuki in the manual is 2.9 to 3.1mm and the EBC plates are 3.15mm, so are a bit thicker. Also the EBC springs are 3.5mm longer than the new Suzuki originals. So plenty of options there to prevent clutch slip in the future.

I will soak the plates in oil overnight and fit them with the original Suzuki springs I bought to opt for easy clutch lever operation. If there is still slip which I doubt then I will add three EBC clutch springs with the option of going to six if I have any clutch slip in the future.








BTW I have checked for clearance in the pushrod area and everything is OK there.

I took the bike for another run this afternoon with my daughter on pillion and going up a steepish hill gunned it in 4th, the tacho instantly hit 8 grand with no increase in speed. Definitely starting to slip badly now. I'm going to have pull it off the road soon and swap out the parts. I think I will go with three standard springs and three EBC springs as Dan suggested to make sure it doesn't slip any more.

I was hoping to get the motor run in before I had to do this, but no luck this time I guess. I have 380 odd miles on the motor now. Not blowing any smoke, so the rings seem to be bedded in OK. Will soon have to think about retightening the head nuts, etc.
