Aftermarket clutch weight testing from this weekend

[Motorhead]

That's what gets me. How do we explain the variability with the clutches? The Proto's ran over 120 some guys here are getting over 120 and then others are having coil bind roller problems and blowing belts.

The protos were running 122 speedo on snow!! No stock sidewinder will do that. Yamaha must have had a different flash for their protos, easy for them to do and it was good sales and marketing.

Different aftermarket guys are flashing for a 25 - 35 extra hp without exhaust so it was very doable don't you think?

Yes that is impressive, not sure mine will do that but hoping for some fast conditions now that I have a pre studded track to let it roll. Conditions make all the difference in speed.

Am I safe to assume his sled did that on hard pack icy trails? Even then WOW his is strong!!

Yes,he had to run his scratchers it was that hard,and he is completely stock. Mine wont be stock,so I am looking for mid to high 130,s out of mine.

Contact Allen Ulmer I believe this one may be an STM made,but I would go thru allen,and it was only $95 bucks,i think he has them listed on his site Dan.

I have a stm 38 I would sell for a little less. It has 15 miles on it.

$110 isn't to bad. I paid more for my dalton.

Any thoughts on the TP options vs the Dalton 35/39? (Especially in regards to stock with TP clutch kit.)
