SlowerThanYou Posted December 20, 2014 Report Share Posted December 20, 2014 thats odd, but interesting the rippers ran more mph and slower 60. We didn't have the clutch fully tuned for the Rippers. Quote Link to comment Share on other sites More sharing options...
MRSHEE2014 Posted January 13, 2015 Author Report Share Posted January 13, 2015 We didn't have the clutch fully tuned for the Rippers.Now you comment about the clutch tuned for big tires on Maybe small motors. To not kill the motor and pull the big tires? Whats the best? Add weight to the lock out o stay with the standard lock out? And soft or hard springs? I would really aprecciate your help Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted January 13, 2015 Report Share Posted January 13, 2015 There is a whole write up on clutch set up that STY spawned in the drag section. Check it out. I'll bet it answers any questions you got. Quote Link to comment Share on other sites More sharing options...

Now you comment about the clutch tuned for big tires on Maybe small motors. To not kill the motor and pull the big tires? Whats the best? Add weight to the lock out o stay with the standard lock out? And soft or hard springs? I would really aprecciate your help I'll start with the 1st quote, because that was the root of our problem. The problem we was having with the 12 paddle extremes was not being able to shift into 4th gear. The last gear we were using in 300', we leave in 1st for a couple of reasons. The main one being we have a 1-4 override & manual 5 & 6 trans. Anyway, we determined it was spinning the tires during the 3-4 shift. So, we decided on the 14 Rippers to get the hook & it did. That's why our Ripper mph went up over the Extreme mph. Plus, we were able to shift into 4th gear no problem. Now getting to your quote. Our clutch was tuned for the extremes & not for the Rippers. The only change made to the bike was the rear tire change. The results was killing the 60' from low 1.30s on the extremes to low 1.40s with the Rippers. With some clutch tuning we were able to get some of the 60' back to mid - high 1.30 with the Rippers. With more time on that set-up we would have matched or bettered the 60's, but we decided a bigger motor was better. Whole different story, LOL! Without getting into specifics, the Rippers pull the rpm down farther than extremes did at the drop of the clutch. We started lowering the primary clutch pressure using the springs. To raise the rpm when the motor loads the clutch. We needed to lower pressure even further, but sold the motor. As for the lock-up weight. We have set weights we use & very rarely do we need to change them. That came from many years of trial & error. Same as all the other clutch tuning. Like Tricked said "There is a whole write up on clutch set up that STY spawned in the drag section. Check it out. I'll bet it answers any questions you got." Hope that answered what you were asking, without me giving away too much information. Quote Link to comment Share on other sites More sharing options...
