Regarding the light aluminum arm [high elevation setup] guys who want to run my stuff, its only a helix change.
Calibration:
"brp high elevation kit" as installed.
Trade out brp helix to my SMT button or S8R roller helix
Set clicker 4 for 8~11K'
...go
I send along a packet of setscrews with weight values just in case if you have to add a 4/10" of a gram at a time.
Quick engine rpms when flipping the throttle. If the rpms are slower than expected, then we go through a little troubleshooting questions to solve.
I'll bite
I have your kit, and I've been pretty happy, but I think there may be some room for improvement - for my body weight. I also have an electronic gram scale and have matched my pin/arm weights.
RT 162, Al's can, clean raves, clean throttle bodies, clean clutches, 21-51 gears 9 tooth drivers
steel arms 81gm
std roller 10gm
10.8gm hollow pins, have available balanced .8gm threaded inserts and others
fresh Dalton grey primary spring 205-328
your S8R7 dalton helix
fresh Bombi purple 225-300 (also have tried fresh Goodwin blue-white 220-335 which has nice backshift but not dramatically different from bombi prpl)
me 275# in my skivees - My clutching needs are never gonna be the same as guys who weigh 175-200
In the winter I ride 3-5000 ft in WA state, central Cascade mountains - weather tolerant area (clouds). Your kit works pretty good with 11.6 gm pin wt. click 4. I'm happy here.
In the spring, when the weather is better, I ride Mt Baker and Bear Paw mtn. One area of Mt Baker is BigHouse. The base of BigHouse is ~6200. Above big house is 7200-7500. The crevases above 7500 are too numerous for my liking. However I want the sled to be all that it can be in case I do have to power over a crevase.
Couple weeks ago we go to MtBaker and sled runs good down low 4-5000. 11.6gm pin wt and click 4. We go higher and I start getting the bouncing betty rpms. I click up to 5 then 6 and still have the bouncing betties at 6200 ft.
Last week go back to Baker with 10.8 gm pins (took out the inserts). Start at click 3 for low elevation. We play on the eastern side, working our way up through several skate park valleys. The day was very warm. Snow depth exceeded the 12' probe. We get to 5800-6000 ft, by GPS, and I start getting bouncing betty rpms during a climb. I click to 4 and there is improvement. I click to 5 and I start getting the straight shift - engine goes straight to 8000rpm and clutches open/close to get me up the hill in a strong manner. Limiter strap is out for spring riding, so I do a bit of a wheelie up the hill. At 7200-7500' I'm running reasonably strong, but not as strong as at 6000'. I could go to click 6, but my seat of pants feel is I would like a little less pin wt. - but wait, my pin is as light as it will go.
What are your suggestions?
