clutch problem with bec

well hi there everybody i'm new here hoping for some advice... my problem.... i have a fireblade 919 sc33 engine was running fine till the clutch started slipping.. so now i'm needing to fix the clutch but the engine number sc33e 211****** according to a very helpful chap at the honda main dealer is for a 97 year model ... but the clutch appears to be from a 983 engine and only has 8 metal plates instead of 9 that a 97 model should have .... has anyone any ever encountered this on here ...

From a CBR forum, I could be wrong but the CBR 900 and Fireblade seem to be the same bike, but I wasn't much into sports bikes...

1996 will be SC33E-2000......
1997 will be SC33E-2100......
1998 will be SC33E-2200......
1999 will be SC33E-2300......

This is a link to a detailed workshop manual Linky, maybe this will help?

thanks for the reply you've obviously researched it a bit .... this sounds odd but my sc33 97 year engine seems to have the wrong clutch in it and the word is that you cannot fit the clutch i have just removed hmmmmm ... got the engine off ebay ..the man i got it off was a clown it took a month for him to send it... just so then i have no come back on it .... his name is craig burke he used to trade as mr remap from kent area.

Are there part numbers on the old plates that make you think they're from a 983 or is it just the number of plates that make you think that?

Could it be an aftermarket upgrade clutch that was different (clutching at straws here ).

Clutch slipping/failing is not a surprise with a bike engine in a car.

The clutch was designed for a lighter vehicle - the bike was approx' 200Kg without a rider on board. Putting that engine/clutch/gearbox into a car is likely to result in drivetrain failure or at least RAPID wearout.

How heavy is your car?

I'd be looking to fit an uprated clutch - rather than the original Honda clutch.

What has that got to do with the OP's question?

But you're right; my clutch/drive train has only lasted a little bit under 50,000 miles... so far.

OP, general concensus is that original friction/steels are best but with Barnett HD spring upgrade.

As anyone who tows knows, if your pulling something heavy don't accelerate whilst the clutch is still depressed. So long as the clutch springs are strong enough to not slip under full load, it won't wear much at all.

With experience, the standar clutch is fine under normal road driving. BUT it will need new friction plates periodically and is better run with upgraded springs. If the clutch is run slipping for any length of time it will ruin the steel plates, that would otherwise deglaze and be fine with new frictions
