Mine was pretty much the same with the new clutch. I was already running stock weights tho, so just the spring change.
I don't know squat about the new vs old clutch, but from your rpm and speed numbers, it sounds like you have to much overall weight, but not enough of it is in the tip. What is your current magnet placement count?I finally got my replacement clutch today for 21 XPT. I think I read somewhere that the new clutch, being heavier, was needing lighter weights than the charts that come with clutch kits were indicating. I have 53/12/12% gear reduction, 35 " Roxxzillas, AA stage 1 tune and AA stage 3 clutch kit. Can anyone confirm one way or another?
First impressions are that it's better than the original. Engagement is super low (1650rpm) and smooth. It's a little lazy and readily hits the rev limiter at top speed (70mph). Rpm at 55mph is 7800, so it definitely needs some tuning. This is with AA high load helix and gold AA secondary spring.
I'm open to any input or suggestions, thanks
I trying to learn here, would not a higher rotational mass affect rpm?Cutch weight are dependent on elevation for maximum HP @ elevation-
I have not heard that the overall weight of the clutch is any heaver, and with the rotational mass ( if it is) would not effect weight /springs combination-
Primary is RPM sensitive
If it was I-- Myself I would weigh that clutch if it was a concern., and see the gram difference.I trying to learn here, would not a higher rotational mass affect rpm?
My elevation is 0-3000 ft
I haven't tried the aa weights in the new clutch. My engagement rpm is around 1800 with the silver/yellow spring, so I'm happy. I pretty much just do low speed rock crawling. Just looking for good belt grip and low engagement rpm.Ryan, did you ever try the AA weights in the new clutch? I did this morning. 0,0,2 with the silver /yellow stripe primary spring, I gotta say, it's pretty good. Way better than the first clutch. 8400 rpm at 55 mph and engages about 1950 rpm. Top speed is about 80mph. Doesn't accelerate as good as the AA HD clutch that I've been running but I would be fine with it doing what I do.
The AA limiter washer does not fit the new clutch.
