Think i am running too steep of a helix??

[Snorider]

going with a new clutch set up this year and can't remember who told me or how i ended going with 40*(team roller) with red w/black stripe spring. But I run great up to 3/4 throttle(around 7300 rpm) then anything after that it loads the motor up and i drop down to about 6300 rpms.

it feels like i am not able to pull my secondary set up, so i was think going to 38* or should i go lower?

also the primary is in perfect shape, and I threw lighter weights in just to see what it would do and nothing changed.

any thoughts?

What motor,pipe, and jetting??? If you are jetted too fat that is exactly how it will act.

02 800, twins, 500/490 jets. running around the 3k-6k mark.

Hadn't thought about it being way to fat though.

it also has vf3 reeds, air horn, 156 2 1/2 track. primary is black w/red stripe, started out with 66g weights. thinking of maybe going to a stiffer spring in the primary though.

Drop about 5 jet sizes to start. You are way way way fat.

You will probably end up with 64g weights, and jetted 430/440, maybe leaner. Thats where mine started to pull at and was still a bit rich at the same elevation.

Mine is an 03 800 so you do need to be richer than mine but.... at 0-4000' with race twins,ported and 3-6000' slp head I am running 360 mains!!! 420's it will run ok but very fat. You are running higher elev than me though so I would try somewhere around the 420-440 mark and try it again. I am running 66g weights so you may need 64's up higher. I am running the slp green/pink in the primary of 4 different 7 and 800ves twins with twins and love it.

i would start at 62g and a softer spring....140-300......03's use a richer needle and smaller mains...jet your 02 to 410-420's as suggested, polaris 62's can weigh as much as 62.8 grams, 64g is too much at altitude unless you go down the 165-340 road. Helix at 46-34. You will not be dissapointed.
