Right now I am running the yellow/white primary and 80g cat weights and a shift assist in the driven and it goes pretty good. I was thinking of changing the primary to orange/white and wondering if anyone has any feedback on the Helix. I was thinking of a Speedwerx progressive Helix but unsure of the one to get. Oh yeah its gonna be for aggressive trail riding.
The only other mods I have are the Ypipe and intake. Thanks

Where are you riding? Elevation? 80grams of weight is a ton of weight for a 700.

looks like he has a 800

I think the stock helix is a straight 36(2007). I am not sure what the 2008 has in it. I have a bud with a f8 tony stewart and we are putting in a 52-34 and adding 2-3 grams more per weight in the Primary. I will update you on how it works soon.

Yep, that's what it looks like, but the 800 is only a few more HP than the 700, and 80 grams is still a ton of weight for that. I don't think anyone is going to be able to recommend a helix for that, because I don't think anyone else runs 80 gram weights on a basically stock 800. But good luck with it ...

i know for 2200' at home 77 is lots of weight for my 800. revs are at 7400-7600. i have that shift assist. if it was out maybe it would rev more.
