Geared down M1000 guys, what weight are you running at altitude?

[AaronBND]

Just curious what primary weight guys are running on geared down M1000's at altitude? I am running 75g at 5-8K which is giving me about 7600rpm's with the SLP exhaust system and am wondering if I would get less belt slip and clutch heat by going up a couple grams like 77-78. Just wanna hear from guys. I am not having clutching or belt issues, just am curious. Thanks!

Been up and down and really like 57/63 at 6-10,000 feet.

Have a couple sleds running 55/65 and they have great belt life and don't give up too much on top.

55/65 gearing with 63 gram weights on a 4 post with STM billet guts. Ride the CO and WYO Rockies.....primarily 9-12K. Speedwerx setup 7600 RPM. Rips it!

Yea, but what weights you running in them Eric? I am actually 57/63 and like it also.

78 grams with Speedwerx black spring for the piped sleds and 81 with the same spring for the stock pipe.

Thanks

I geared down to 55/65 and am running 75 gram Cat weights and my top rpms are 7600. I ride 5-7k. I tried the stock 80 which I was running last year with my stock 60/60 gearing and I couldn't pull r's so I droped to 77's and still was shy so I dropped to the 75's. I would like to try some 73's and see how they run but the 75's are close. I am running the AC Red spring in the primary and the red/white tortional in the secondary. Shifting is lazy but my belts are lasting longer with the softer springs.
