lock up clutch

[hotwheels000]

I know I asked a question about clutches before and I was directed towards a lock up clutch. Can anyone tell me how it will help me from burning my clutches out. I know at high RPM it will eliminate clutch slippage but will it help for drag race launches..........on the throttle landings from jumps............ and what about the high speed runs through the whoops........... I have got to believe that when the wheels are under power and bouncing of the tops of the whoops or landing from a jump that this will cause some slippage also . Maybe I am wrong but I dont want lay down 1200.00 for the set up if it wont solve my problem. Thanx

I just added a MTC 2-Stage lock up to my GSXR-1000. I added a turbo during the summer, which the stock clutch could'nt handle. Lock up clutch solved the problem. I took it to glamis T-Day weekend, broke the 530 heavy duty chain and broke 4 teethe off the 64 toothe sprocket. I should have the new sprocket and chain on this weekend. This time had Sprocket Specialities do the Titan Tough option and Link Lock option. We'll see how it works out next trip. Good Luck.

What is the difference between a 2 stage and single stage.....did you have any problems dialing it in or is it preset pre-set ?

With the 2-stage lock up clutch, the 1st stage is the primary setting before the lock up goes into play, the lock up is the 2nd stage. According to MTC you can use stock springs and add their .025 or .050 thick special spacers on top of the springs. The spacers add more pressure to the springs for initial engagement. I got my clutch springs and plates from Schnitz Racing.com, there suppose to be stronger. I modified my cable clutch to a fully hydraulic clutch slave with CNC peddles. I cut out the old cable mechanism on the spocket cover and fabbed a aluminum adapter plate. First slave cylinder I got was from a motorcycle junkman. He didn't know what type of bike it was off. I used it for one season but it leaked bad, went to numerous motorcycle shops but nobody knew what it was. Finally I saw one on E bay that matched. I ended getting a new one from BikeBandit.com. for a few dollars more than the used one off E-Bay. It ended up being off a Yamaha YZFR 1000 mid 90's. I've heard if you don't beef up where the slave cylinder mount is, it might crack with the extra pressure of heavy duty springs. I've seen on different motorcycle performance sites reinforcement brackets. Hope this helps.

Hotwheels,
With the addition of the differential to your buggy, how big of an issue will this be? Won't the diff absorb a lot of the stress (for lack of a better word) that was affecting the original spool drive, chain and clutch?

I was wondering the same thing sounds like you are thinking like me and the new diff may absorb the abuse. Do you have any more thoughts or experience with this helping the isssue

thanx

Hotwheels,
Unfortunately, no. I have zero experience in this arena. My current buggy has a CVT tranny with spool, so the clutches just slip the belt as needed. I'm planning to build a 'Busa powered buggy soon, with some type of rear diff and am researching the needed parts.

[dirtbag]

a diff will most likely dissapate a bit of the stress on the rear end.I installed a spool on a high powered rc truck and all I did was break axles immediatly so I kept trying till I broke 4 of them.put the diff back in and I was once again free to drive like a fool,the diff will let the tire with less traction give a bit

[diirk]

Makes sense. My buggy isn't putting out enough power to stress a spool. I would really like to have some type of locker in the rear, but I don't see that happening. The low speed handling pretty much sucks without a diff, but then again, I don't really drive slow to often. 8)
