I ran into that with the 102c on the fan. Believe it or not the old school hex clutch is faster on top. We tried everything we had...

same

Ran again the other day... No matter what we did ran the same MPH. Took off the comet and put the hex back on and kept the newer cat secondary with a 50/44. Changed belt back to a inch and a quarter. Gained 4 mph. What the hell... It feels waaaay better and launched waaay harder. Does not make any s...

If you have the smaller drivers these are geared way to tall in my opinion. We tried larger top gears and its just too much. I want to get the thing to run out of gear and overrev at just over 80mph for what I'm doing (if it will go over 80). I have talked with guys that are running a 15/36 on the g...

Did not seem to make any difference taking the coil out. Its not that loud but sounds really good. Those coils are junk. We had a sled we absolutely could not get to run, cut the end off the pipe and it had "uncoiled" plugging the exhaust. When I got mine we cut it open same thing so I too...

Got to run yesterday more. Could not run 1000 feet but probably 800. Brought a roller secondary, a ton of helixes and weights. Ended up on a heel clicker spring 360 finish (big) 64 gram weights, 55 degree helix on a button clutch, yellow spring. We left the set up in the other sled that ran 79mph la...

A 19 will easily work with a stock chain, its huge. In fact a 21 will fit. It snowed like crazy and then got warm so we lost all our lake spots. I'm back to a 18 tooth and am going to try a 17/36 as soon as I get them. These are geared soooo tall. We did try more stuff. I have 64 gram weights in it ...

Forgot... Brand new rebuilt motor. .080 timing Hewtech CDI, new stator, cut out the coiled mess in the can.

We are running new style cat clutches and have been running fiarly shallow helixes until the other day. With a 18 or 19 we are not running out of gear. The things just would not pull at all so we decided to try something totally different. We had been running basically what Comet calls for with a st...

I've heard of people cutting off the end of the pipe and taking that coiled baffle out. What do you guys think? I would think it would lose some backpressure

What are you guys getting for speeds with your Twisters? We have two 76 Twister 440s that we have been playing with on the lake. We can only get about 70mph on radar with each no matter what we do. Funny thing is my 75 Rupp fan 440 ran 75mph in the same distance. I started mine set up like I read on...

Need a 340 or 440 trail twister pipe. I don't need the Y pipe. Thanks, Roger

There are two purple springs.. which one??
