Cutler 1000 and 1150 Clutch Specs

I am running 671/70 weights ,yellow with green stripe spring in primary and green spring in secondary not sure about helix ,on cutler 1000 with bored carbs and twin pipes....

1160 set-up

I'm running at 5000-7000 ft the following

76 gram heavy tips
140/320 primary spring

58-46 progressive helix with a red white 3rd or 4th hole... My sled runs about 200 Hp

running 19 - 40 gearing with 8 tooth 3.0 pitch and a camo extreme.

Pulls hard.... Good track speed...

Stay away from Cat dual angle helixes - Backshift isn't great with them... Use a billet if you go progressive

The above works well with a 49, 51, or 53* straight cuts as well...
