lockup clutch question....
I am going to be upgrading my clutch soon, and i am considering either the full muzzy setup, or the MTC lockup. I am wondering what a lockup is like on the street,and what the wear characteristics are like. I still ride my bike everywhere, everyday, so i need 100% reliability. I will be making 245-255 hp this year, with a 6 in. ext. arm, so i'm wondering if a conventional clutch will stand up, even the muzzy.

My lockup isn't bad on the street, but I imagine you could get away with stiff springs. If you are going to dragrace a lot, definitely get the lockup.

That mtc lockup is very streetable and will not break like the Muzzy lockup.IMO it is the only choice there is right now.

OK,Its not the lockup thats breaking,its the puller shaft or whatever its called.The mtc uses a support that he installs in the clutch cover.

I broke at least three pullers, and I wasn't happy, all on race weekends. Lucky Ryan Schnitz had a spare in his trailer when I needed it most, and I ordered spare from Ron Ayers to take to Maxton, glad I did because I didn't even get down the pit road before it snapped. Sold the Muzzys. Anyone with the MTC can you post photos and pricing? I'm interested!

2 passes. No street riding. The design is flawed. If you launch hard it breaks. Even if you dont; sometimes it breaks.

The MTC Multistage lockup puller I saw has a hole drilled longitudinally in the shaft to lubricate the slot where the arm engages the puller arm.

BTW I am also going to be running the mtc multi stage lock up have a muzzy on it but after buying 11 clucth pull rods I called it a friend has the MTC rode his bike 9 passes no problems. You know the cool thing about that is my buddy was having problems with it and he told tony Tony shut down his display came to his trailer set it up for him and spent 1 hour foolin with it and also gave up tuning tips etc, etc, any lock up clutch I buy will be MTC now that's customer service I guess thats why they call him Tony the tiger CAUSE HE'S GREAT

Has anyone tried to "deep freeze" the puller shaft?
I know heat is the enemy of this poor little part. Perhaps a bath in a cryo tub could render more use out of one? Mine failed like yours in the picture Bergie...but a lock up was not to blame. Making 11 passes in 90 mins was...hehe

Two of my friends have bought the Muzzy lock-up and both have broke. When I get the cash it's the MTC for me.

Steve, they all break. The metal isn't strong enough. I had several local machine shops look into making a billet piece but the cost was too high and it was no guarantee it would not still fail. Muzzys is aware of the problem, IMHO they should pull the product until a fix is distributed. It is possible to use it without breaking by leaving at idle and just releasing the clutch entire with very little load/RPM, but that defeats the purpose because I bought the product for racing, can't race without launching hard. If you're out of the clutch entirely by 5500 rpm, it will work. Anything over that especially on a big motor or nitrous, forget it the weights will expand and break the rod.

Thanks for the info guys. I've launched about a dozen times at 9500 rpm on my muzzy lockup. Didn't experience any failures, but took the lockup off for other reasons last fall. Will give strong considerations to either running the stock setup or a MTC this spring.
