primary clutch help

[robosledder]

i was told to run 91 gram weights on primary with a different spring just because i have evo cold air intake . boost tubes . brv valve . highjacker 1.9 they say if not that my rpm will be tagging my rev limiter is some one pulling my leg ?

that sounds about right, I haven't installed mine yet and don't remember exact weight, but I had to change weight and spring because of EVO 215 and new can.

I had a Hijacker 2.0 last year and ran 90g cutlers. They were too heavy.

What elevation are you at?? At 5000 feet to 10,000 feet I can tell you that the 1.9 Hijacker will not pull extra weight.
