robert.b.west Posted April 5, 2011 Report Share Posted April 5, 2011 I took my serval out over the weekend and was drag racing at silver lake. The drag is set up so the start is in very wet sand. The motor ran great. The clutch on the other hand was not so great on the drags. It could not hold the power. I currently am using a toomey clutch with 100% stiffer springs. (Not the easiest to pull) So.. when I got home I ordered my lock up. I am going back in two weeks and will report back on how I like it with the lock up.

Shane is running a FAST clutch with no lockout on his Serval, and there hasn't been an issue with slippage so far. Quote Link to comment Share on other sites More sharing options...
robert.b.west Posted April 5, 2011 Author Report Share Posted April 5, 2011 I was going to try a fast clutch but if it is not enough, I would just be wasting $100. This clutch was purchased while I was at the dunes hoping it would fix the problem. It did not. I would have rather had a fast clutch but all they had were toomeys.

jbooker82 Posted April 5, 2011 Report Share Posted April 5, 2011 How much riding did you do with the clutch slipping. It might already be smooked. Fast clutch with 6 oem springs and a lockup would be a nice setup. That is how I run my clutch. Quote Link to comment Share on other sites More sharing options...
Snopczynski Posted April 5, 2011 Report Share Posted April 5, 2011 jeff at FAST advised against the lockout and said to see how it did with just the clutch unless we were going to make the serval have a ton of hp and torque. The lockout will add bite, but its also going to add rotating weight to that clutch basket assembly. What is your serval setup like? Quote Link to comment Share on other sites More sharing options...
robert.b.west Posted April 6, 2011 Author Report Share Posted April 6, 2011 I probably only rode a couple hours on the new clutch with proabably an hour or so of drag racing. The setup is nothing crazy. T-5 pipes, 33mm pwks, 22cc domes 160psi, +2 on the timing Quote Link to comment Share on other sites More sharing options...
RagunCajun Posted April 6, 2011 Report Share Posted April 6, 2011 I went with an undercover slingshot. Cheap and using light springs provides a light clutch pull. More expensive than a good clutch but i hate 6 HD springs. Quote Link to comment Share on other sites More sharing options...

More expensive than a good clutch but i hate 6 HD springs. Yep. That is what I got. The 6 hd springs suck. They worked on my ported 350 but so far have not worked for me on the serval.

RagunCajun Posted April 6, 2011 Report Share Posted April 6, 2011 You have a slingshot and are still slipping? Quote Link to comment Share on other sites More sharing options...
cmbarker1979 Posted April 6, 2011 Report Share Posted April 6, 2011 Anything over 65hp should have a lockup or slingshot. If not you will slip and burn through clutches alot faster. Lockup will improve clutch life also Quote Link to comment Share on other sites More sharing options...
robert.b.west Posted April 6, 2011 Author Report Share Posted April 6, 2011 You have a slingshot and are still slipping? lol no. I was slipping so I decided to buy one. I said that is what I got because it is on order. sorry for the confusion. Quote Link to comment Share on other sites More sharing options...
STINKYDELUXE Posted April 6, 2011 Report Share Posted April 6, 2011 I ran a Boss 8 disk clutch with no lock out on my 10 mil Cheetah with no problems and a the Boss clutch costs less than Hinson. Quote Link to comment Share on other sites More sharing options...
Snopczynski Posted April 6, 2011 Report Share Posted April 6, 2011 We have 7mm re-sleeved cub motors running just heavy duty clutches without an issue, so I am not sure I feel the same way about the lockout. I am not gonna run one when I put in my Serval from everything I have seen on Shane's motor so far. Quote Link to comment Share on other sites More sharing options...
dirtydownunder Posted April 6, 2011 Report Share Posted April 6, 2011 i run a slingshot in mine with 6 stock springs, mainly because after trailing for a while my hand gets all bitchy. Quote Link to comment Share on other sites More sharing options...
05stroker Posted April 7, 2011 Report Share Posted April 7, 2011 I haven't had mine in the sand yet, but I did have it on the dyno and I did not have any slipping. As Snop said, it's the fast heavy duty clutch with 6 heavy springs. The lever is a little stiff but I have one of the easy pull levers with the bearing in it. I do have a slingshot incase this doesn't hold up at the dunes next weekend. I just don't want to add the extra weight to the tranny if I don't have to.
