700 redhead with a single pipe and all the usual mods.Would these weights be worth running?Probably 50/50 trail and off trail riding......
I am gonna try to set up set for trail use this yr
I would say yes, if you can get traction. Worked very good on my MM, and they have tuning instructions too. I like them. If you don't like their set up, you can ask for one here.

Joe, who notched your set? how high did they engage? sorry to get off track Swede, I think you'll be able to get a good setup with them for what you're doing.

Joe I Have A Race Set-up For A Srx For Grass And Ice. I Had To Notch Mine Too To Get Engagement Up With Red Spring Over 5000. I Assume This Is A Sx With Triple Pipes ? 3:16 (yammie Tony)
Phil Stanley PCS Performance Did mine They take about 5500 No gonna put them on single pipe unless I get another set of pipes to put on it.

SINGLE PIPE ON A SX RUNS AROUND 8300 PEAK. ONE THING ABOUT H/C, YOU MUST HAVE A GRAM SCALE. TIP CONTROLS ALOT ON THESE. MID ALSO CONTROLS HOW FAST YOUR RPM WILL CLIMB. HEEL WILL AFFECT ENGAGEMENT SOME. I ASSUME YOU HAVE ALL TUNEING SCREWS AND WASHERS. THESE ARE SIMILAR TO YAMAHA 8CA AND 8BU IN PROFILE. INNER hole WILL TAKE LESS THAN TIP. I WOULD START AROUND 50 GRAMS ACROSS THE TABLE WITH LIKE A 52/40 CAM. ALOT OF TUNING HERE BUT ITS FUN. USE THE HEEL CLICKER RED SPRING. 3:16 (yammie tony)
I have found out that it seems like the weight of the heel is the most important way to affect the engagement speed. I always put the weight on the tip and heel. For engaging at approx 4200, with 15 mm rollers, you need about 5,2 gram in the heel. Make sure the washers on the bolt that is on the heel do not interfere with the roller when the clutch slams slut.

Thanks guys, I rode a sled similar to mine that was setup with these and its very impressive to say the least! I'm gonna run 5 grams in the heel and tip with 15 or 15.6 mm rollers and a red spring in the primary. 48/34 Dalton helix with a green spring in the secondary and try this for a baseline. I'll let you all know how this works. This setup is from Mr. Viper and we all know that he knows his stuff! He said that this should get me close.....

Just a note to add....if your gonna run trails the red sec. spring will work very good, if your gonna be off trail or wet heavy snow/(big lug track) the green will be the one.
I use the red sec spring most of the time 80-90% it works very well with that helix and gives great topend.

I run probably 75% trails and the sled has a 136"X1.325" Cobra track with 39:21 gearing. What would you choose for secondary spring for my sled and do you have a preference on the roller size?mrviper700 said:Just a note to add....if your gonna run trails the red sec. spring will work very good, if your gonna be off trail or wet heavy snow/(big lug track) the green will be the one.

I would first try the red at 80-90 twist, although...it may not be enough with the bigger lug track your running. May work well in dry snow but the later season wet heavy snow it will likely cause a issue with low rpm or overshifting.
If you cant seem to get past the little bit of overshift you may need to go to the green at 60-70 twist, it will hold it better on the upshift and make it backshift slightly faster, but it will scrub a couple mph off the top if it matters.
ADD: roller size, its easier to get a nice shift curve with the 15.6mm rollers, but the 15mm also work well.
Its the 14.5 that are kinda hard to control, too much power, too soon, with the smaller roller.

I read in the instructions that 14,5 mm rollers might cause the heel to touch the sheave, don't ask me how.
