Lots of testing and believe we have the offset nailed down

This one is at 61mm !
Tomorrow both clutches coming off and full disassembly and inspection.
Also need to make sure his stub shaft bearing is seated properly to make sure the offset measurement is accurate before machining

What a mess!

What a mess!

They will be pretty once I am done

I’m running a 45 degree helix with HH thunders at 67 grams. Thunder orange at 6/3 in secondary. 22/41 gears. Offset set with hurricane bar. 3mm machined of secondary stub. 10k miles no blown belts. Floats the skis up past 80 mph easy on hard pack. Temped with gun and hands tons of times. Never seen over 160 on primary or belt. I know most think this is to much helix. But I’m going on a tree trunk saying more helix angle really wakes these winders up. 270 tune. Corner to corner is hard steering as the skis just float about 2-3 inches.
57.4 mm offset!!!!’

Ah, didn't I say 45 or 46 as I recall?

Wait, we're in the wrong thread.

Full shift with belt in secondary no spring. 1-1.5 mm clearance on back side. Bushing safe at full shift. This is IMPORTANT for guys that are going to machine off secondary. Make sure you don’t go to far.

I’m eating Knapp crow sandwich mike. You were right again.

I knew you were waiting!!! Didn’t take long !

Curious why there angles are so far off, I could see if it was between 37-40 I guess that would be "acceptable" but thats way out there. Wonder if all there angles are 7* off or if this changes depending on what angle you get?

From what I see they are all off like that. I had a buddy burn right thru the secondary trying to run a stm helix before. I always thought they were just cut wrong, but that's their MO.

I ran a Dalton 45/33 the last 2+ seasons and loved it. I really think the Heavy Hitters give you the backshift you are giving up with the steeper helix.

No issues with backshift at all. I know it goes against clutching 101 but mine back shifts great. Probably the way I have them loaded also. Stacked in the heels. Middle empty and the tip stacked also. That 45 start I bet you like!!!

Who's 45 are you using?
