Lockup clutch setup
Looking to get a lockup clutch on my 12. Thinking mtc. I've been raceing for a few years and got the bike how I like it. The only thing missing is to be able to toss the clutch lever. Wondering if there is any help available on type of lockup and how to set it up. Bike info: 2000 zx 12r. 12in over stock. Pc3. Brocks full exhaust. Penske race shock tuned for length and weight. Geared 16/46. Muzzy clutch upgrade. Mr12 fuel. We run 1/8 mile up here mostly. Best pass 6.09 120mph 60 fts. Mid to low 1.50s. Any info would be cool. Thanks

I run the Hays Convertable Lock up in my 12. It is very nice but it is expensive. I have also run the MTC multistage before also. My best 60 ft. with the MTC was a 1.40. My MTC clutch is for sale if you are interested.

I've looked at the hays and I agree it is expensive but I do like the multiple options with it. I just run a stock motor and I don't even know if I need a lockup. What makes me think I do is my top end mph varies from time to time even with heavy springs the clutch. Also it would be nice to be able to set up the clutch to throw the lever harder.

In your opinion witch do you think is better? With the hays clutch do you have to send your basket away? Can you run the mtc as a single stage lockup. Sorry I'm full of questions but I'm from North Dakota not a lot of info up here just internet

With a stock motor you should not need a lock up clutch to keep the clutch from slipping on the big end. The Hays clutch is flat out awesome when it is tuned correctly. Clutch tuning is key with any lockup. For the Hays clutch you have to send him the clutch basket and the hub. The MTC multistage can be run as a single stage lockup.

I've run both in my 12 and I think the Hays is easier to tune and much more consistant. With the MTC my runs were all over the place and the temp really affected the clutch. With the Hays my runs are very consitant, Last weekend I had 6 eighth mile runs all between 5.71 and 5.74 with 3 - 5.72's in a row.My bike is 63" long and usuall have 1.41 to 1.43 60ft. I have the older Hays 3 arm convertable clutch. The newer 6 arm will allow finer tuning but also allows more option to make mistakes?

So if I could afford it I should go with the hays? Is it possible to tune them so you can toss the clutch at the hit or is it still a clutch throttle management game. If you guys don't mind sharing a little setup direction it would be much appreciated. I understand if you don't. I hear so many horror stories I don't know what to believe. I think that is the reason I haven't gotten one.

Both the MTC and the Hays can be tuned so that you can toss the clutch lever and pin the throttle on the launch. Like blueshark said the Hays is easier to tune and more consistent. As far as setup and tune it will be different for different bikes and riders. The setup I run in my bike probably won't be right for yours. You need to have a reputable tuner assist you with tuning or spend a lot of time learning to tune it yourself. I highly recommend getting someone with a lot of experience to help you tune it. It will save you a lot of time. The horror stories you have heard are probably from people that didn't get a good tuner.

I understand the setup will be different. The problem I have is no one around here really knows anything about them. Ii guess I would be looking for just a starting point or maybe someone on the forum who could point me in the right direction. I would guess the clutch won't even be close out of the box? I wouldn't even mind paying for some info. I know a lot of time goes into tuning these things and that info is worth something to me. Thanks again fellas

ive had decent luck tossing the lever with the mtc multi. comparing it to the hays is not really fair though, the mtc is trans driven where the hays is engine driven. a fair comparison would be to the gen 2 mtc

So what do you think. There r just so many options. Iis engine driven or trans driven easier to tune. I guess I just want the most for my money and ease of tuneability. At the end of the day I would like to be able to toss the lever and make sure the clutch stays locked up on the big end.

You can make both types of clutches work, my times were close with either clutch. It's just easier to stay consitant with a rpm based clutch verses wheel speed clutch. At 12" over you should be able to get pretty agressive with the clutch but it will probably surprise you at how little static pressure and weight on the arms you will need to make it work. I can pull my clutch lever with one finger, only problem I have is I also ride mine on the street so i have to be careful not to get on the throttle to hard in upper gears at a lower RPM or the clutch will slip until the arm come in.

Wow it would almost be worth it to make the switch just so I don't have the heavy clutch pull. I'm running all heavy springs so it is a handful. I have heard it doesn't take much static pressure to make them work. I don't know how much truth there is to it but I've heard some guys only run 4 stock wore out springs with bare arms.
