slider or lockup
I live in Canada, and i drag race my 2001 zx12, trying to figure out to go with a single stage lockup or slider clutch, some people say lockup and others say stay away from them and go with slider. I'm running about 200 hp on gas with stock wheel base with 18- 48 combination with 2 step auto shift box with air shifter wheelie bar and slick. Need some input on lockup or slider and maybe a better sprocket combination. Running 9:40 first pass out @ 146.

you will need assistance get back to the pits with a slider.
IF you are running wheelie bars, i don't think a slider will benifit you as much.
MTC lock-up!

A 17-50 worked well for me when I was running close to your HP. With wheelie bars, you could get by with a larger rear sprocket than a 50 though. I would say put as big a rear sprocket as you can without running out of rpm's before the finish line.
I don't have experience with a slider, but the MTC lockup does work very well when adjusted properly. It also saves clutch plates.

I say first try swapping out your sprockets. You need to be methodical about this so that you really get a feel for what each change does to your setup. You should know by now that wheelie bars and a slick require a lot more preparation on the setup. With the air shifter and wheelie bar, I think that you might as well get the most out of your gear box. I ran a similar setup with a 17-55 combination. That put me close to redline in 6th gear through the traps. Your 60-ft times will drop immediately because of the lower gearing. Just watch out the first time you run with this gearing. The first shift comes us FAST.
As to lockup vs slider, the answer depends on the type of racing you do. If you are just bracket racing, the slider will be MUCH more consistent than the lock-up, and there is almost no setup involved. The slider clutch takes care of giving you a consistent launch. I disagree with Ninja12. You won't need help getting back to the pits wth a slider. You'll just piss everyone off because the ones that don't know you have a slider will think that you're gunning your motor and jammin' around the pits for no reason. Because the slider engages with RPM, you will have to gun your motor if you want to get anywhere.
The lock-up has to be tuned for each given track condition. With the lock-up, you will pretty much be doing what you're doing now with your setup games. You will just be adding a couple more variables to the mix. With a wheelie bar and slick, I think that the lock-up will make it much easier for you to get completely lost in your setup. With a lot of test and tune sessions, you will be able to get a decent baseline with the lockup and just change things around depending on the track conditions, but it's still a pain to be dicking with your clutch on race day.
The other advantage of the slider is that it is much better for your motor and transmission. Because it gradually comes on, you never have to worry about bogging the motor. If you bog your motor enough times, there is enough potential of a connecting rod putting a window in your case. The slider will make your motor and tranny last almost forever. (relatively speaking.)
As I see it, there are only two bad things about the slider clutch. They're fuckin expensive, and it's really hard to cut a good light with a slider clutch. If you run with a full tree this is not a problem, but if your track runs a pro tree, and your having trouble cutting a light now, the slider is going to make it even harder to do so.
If you can afford it, and if you run a full tree, I recommend that you go with the slider. You won't even have to change the way you launch. You can just get rid of the clutch lever and replace it with a button that activates your 2-step. You just set your 2-step much lower. Usually, the slider starts grabbing around 4500-5000 rpm. So, you would just set the 2-step to hold ~4000RPM with the button pushed in. To stage, just hold down the button and pull the throttle wide open. When you see the light, just let go of the button. This is also the perfect setup if your local racing organization runs a full tree with electronics because it doesn't take much more to add a delay box to this setup either.

The Bike that Bear Racing used to beat the Muzzy Turbo Kawasaki of Marris and the Velocity Racing Turbo Busa of Brad in SA was a SLider set up. Also his son who only has 1 hand uses a slider set up and none of them get towed to the pits after a run!

Explain how this works without burning lots of clutches?

I cannot "Explain" What I do not know! I SAID That two of Bears Bikes have slider Clutches and that they ride the bikes back to the Pits Period. No more and No less

It's not that hard. You just gun the motor and coast.

Like wannabe said...gun it and coast. If you try and give it just a little gas and ride it at partial throttle, then It'll burn and break clutch plates. personally I won't ride mine back. but that's just me
