Hey Everyone, this is my first time posting in here but I have already learned so much from everyone on this forum.

I am looking for a lock up clutch for a 2007 ZX-10r and cannot seem to find one without spending $2500 bucks for a hays.

Does anyone have any for sale or know anyone that would?!

It is for a land speed racing bike that we are having issues with the clutch slipping causing us to loose a lot of power on the top end.

Thanks,
Cliff

Try psychobike man youll have more luck on there.

Lock-ups for the 10r are pretty scarce... I'm in the same dilemma with the turbo bike. With that said, have you tried some really heavy springs and a good clutch pack? My stock clutch with 6 gnarly springs has held 14ish psi at 200mph on a mostly nekkid bike.... you'd be pretty surprised what you can get away with with good springs.

PS: sauce on that front fender man! I could use one of those.........

I have looked at psychobike but they have a tough website to figure out. But I put up a post there as well.

I have been through 2 clutches trying to figure this out. We put in heavier springs but it did not change the results. I've seen some people use 3 value springs off of a suzuki and have gotten good results. I never thought running with no fairings on spray would put that much drag on the bike. How much horsepower are you making? Our dyno showed 210 with the speed but 203 hp which we are thinking is the clutch slipping.

Thanks! It is a tiger racing fender. It's awesome and whether or not it helps at all it definitely looks cool!

What kind of oil does everyone run? I have been reading that Mobile One 4T 10W40 is very slippery and not good for slipping clutches

You may have something else going on.... possibly wind pushing the clutch lever in at speed? (don't laugh, it's actually a thing they've discovered in motoGP, and those are much more slippery bikes).

As far as horsepower on my bike: never had it on a dyno... but I'd put it in the 270ish range conservatively. Dean had a nekkid 2nd Gen that he's been really quick on... but it takes a lot of power to run the double ton without fairing. I think he ended up with a lock-up on his turbo bike at the end (and fairing). His lock-up was a Muzzy with a Hay's spacer, but I don't think you'll find a Muzzy or MTC lock-up these days.

I think I have six 54 or 56lb springs on my hat right now. I don't know 100% if it's not slipping, but I never saw anything abnormal in my datalogs. That being said, I'm saving up for a Hay's convertible... I think Schnitz is selling them for 2K even.

Opening up a can of worms there... I actually run Suzuki's 10-40 synthetic as I get it pretty cheap from the local cycle shop (like 5 bucks a quart cheap). As long as it's designated as wet clutch safe and you change it often, just about any oil will work. "Energy Saving" oils or friction modifiers should be avoided.
