Ulmer Dyno

Dalton helix will match OEM Yamaha angles. STM will be 6 degrees steeper. If you bought a Dalton 35, it will shift virtually the same as OEM. If you buy a STM 35, it will shift closer to a 41 degree angle.
100% . I was running a STM helix and have some post on here somewhere. I showed the difference with a angle finder. Knapp kind of called me out on this. He was right about the STM being much steeper. Good call Allen and info here.
 
FYI.....I just did TAPP setup vs Arctic Cat ADAPT (primary & secondary), I'll try to post some information here soon.

Gains vs the Cat clutches on consistency as the clutch shifts out is fairly significant.

I should add, this is at bigger pump gas power (160+ hp to the track on pump gas setting).

Good stuff Allen. One thing I fogot to mention, if you are using the button spider, It takes some time to break it in. When new they are pretty sticky with pressure on the buttons from the o-rings behind, arms don't always move freely and buttons don't slide well. Putting time on the TAPP will allow for less arm weight and the clutch to move more freely. On a roller spider its just the arms and you will not notice the stiction at all really, so its a non issue on the roller spider.
 
Allen thank you again for sharing. Always very interesting seeing the correlation between different components. So was this enough info for your customer to pull the trigger on the billet stuff?
