My friends 60 hp shee was having clutch issues for a year. Every weekend out on the dunes he would need to replace his clutch. I talked him in to the lock out and he has never had a problem since.... I LOVE the lock out

dont really need one untill you get up in the 85-90 hp range, till then you are just adding rotating mass to the clutch and spending money on a modded side cover and lock-up

 

I would disagree a bit about the horsepower range you stated, but other than that you are spot on. I think it has alot to do with how you ride and where you ride. If you are drag racing or in the sand, I think the horsepower range you would from which you would benefit from one is much lower.

 

To answer the original question, yes, they work great with a stock tranny. :thumbsup:

Yeah, the lockout's are great to have on a modded shee. I mean I wouldn't put one on a stock bike, but if yours starts slipping and you think that you ride like you will continue to ride then get one. Because if you have to buy clutch packs every other season, then they will pay for themselves over time.......... :thumbsup:

If it is on a smaller motor you can always install it and pull every other weight off or I have seen some pull all the weights off and just run the fingers. This is if your bike is mildly built and is a small motor.

^^^ dude everytime you post I get a chub looking at your bike haha. Not to rob a post but can you slip the clutch at all with a lock up or is it just on or off?

i would never match a lockup with a stock tranny, not because its hard on the tranny but because its gonna be a motherfucker to shift when drag racing. my bros 4mm cub had a lockup with stock tranny for a while. you couldnt shift it unless you backed all the way off the throttle. id recommend going with a duneable override at leats when you get a lockup...

It is getting a slight makeover this winter. That picture was from early last year.

My tranny is mostly stock and I can shift pretty easily under heavy accleration, clutch or not. Of course I have fiddled with the weights on my lockout, but not so much as it perform that differently. Possibly the few different lock ups that are out there perform differently? All the pieces that I have ever owned were made by Direct Drive. :thumbsup:

yea most people who use the lockouts on a 70hp motor prolly arent gonna mess with the weights much. if we had on my bros cub im sure we coulda made it better, but he was plannin to go to a duneable anyway so we didnt bother with it.. the duneable is a nice tranny to have. ours have proven themselves for over a year now.. oh yea, all our lockout stuff is from DD..

Yeah, that makes sense. My red bike on good day only made 72 horsepower on an engine dyno. On a chassis dyno the best I have ever got to the rear wheels is 67 horsepower. The reason I was fooling around with my lock out weights was when I was having a launch problem drag racing in the heavy sand at Pismo. That turned out to be more of a suspension setup issue and I never put the lockout back to normal.

 

I agree that a dunable override is the fool proof way to go. I haven't had an excuse to tear into this engine for a long time and I am too lazy to do it just to change out a transmission I cannot complain much about. At one point, a bit ago, I was going to start making my own transmission parts, but I still haven't started that project. My triple and shenanigans at work have been taking up all my time lately. :thumbsup:
