BMP's Clutch Adj. Weights

[LongHorn XC]

First time trying BMP's weights. Can anyone point me in the right diection to start at and how they work? There are 4 slots for magnets. Do I try to place them evenly over weight for preferred grams? What effects are there when you place more in the heel compared to the tip?

I will be riding at 9-11k (Snowies) and 6-10k (Alpine). For 6-10k I'm guessing I'd be more at at average at 9k. Never been to Alpine, so not sure what to expect.

I'm on a 800 163" 2.6

Any help on some good setups would be great. Thanks!

Each mag is 1.4,grm, id say for your eleavation your gonna need 64 grms roughly, try 1mag each hole with stock blk spring and if it your not reving high enough, take the mag out of the tip.

Do they have the same profile as the OEM 10 series weights? What do the base weights weigh, with no magnets? how many grams does each magnet weigh.

The tip of the weight will control peak RPM, the center of the weight is your mid-range and the heel of the weight is the bottom end, low speed tuning. The more weight you can put in the heel, the hard the primary is going to grip the belt and this will improve your low end power and extend belt life. You will want the heel heavy enough to were you dont seen any black marks down low in the primary, but not so heavy it makes the engine bog. The center of the weight has a lot of effect on how well your engine responds on/off the throttle. The tip of the weight is going to control WOT rpm when climbing, rpm too high = add weight.

Snowies is almost all 9,000-10,000 ft some 10,500 stuff and no 11,000ft unless you are just riding up to a peak to look around.

Alpine the parking lot is down low, around 6300 ft. The only thing your going to do is be trail riding up and out of town. All of the "riding area" is above 8,000ft and most of the good stuff is 8500-9,000ft.

You wont have to make much of a change between the 2 locations, maybe 1 gram lighter for the snowies. Eric

Thanks Eric.

They are based on a 10 series. The base weight is 58 and each magnet weight is 1.4. I just wanted to make sure I was close before riding with these weights in each hole. Thanks for the lengthy reply on what does what.
