More Clutch Questions for M7

[SA Kid]

I need some advice on a good clutch setup for my M7. As if this hasn't been asked enough, but I'm having trouble finding relevant articles with the search. So here goes. I've got an '06 M7 with 162x2.5 track and ride between 4000' and maybe 8000'. It's got an RK Tek head, jaws twins, and a timbersled skid. I'm about 165 lbs soaking wet and maybe 190 with all my gear and pack. Prefer boondocking over chutes, but like poking hills and climbs too. I used to have an SLP green/pink primary and found I would trench too much with a harsh engagement at 5000 rpm so I've got a stock cat yellow/?? white?? and I think they're 68 g weights. I bought cutler adjustable weights before I knew anything about them and they were installed for me. Now I can't recall what they are exactly. As I write this I'm thinking I need more info on my driven and all I can recall at the moment is it's also an RK Tek but I don't know the angle off hand. I'm finding it just doesn't have the bottom end grunt that I would like to see when I'm at low speed and 4500-6500 rpm and want to spin the track and get it spun around quick. I'd say I'm a solid intermediate rider and maybe it's just rider ability, but I thought I'd post this and see if anyone out there has an opinion. I'll check the secondary tomorrow and add to this post if it helps. I did spend some time cleaning up the primary because it was sticking a little and the weights were over tightened (imo) because they did not move freely at all and all that helped quite a bit with engagement. I think, from what I've learned so far, is that I seek the right back shift for my weight and riding preference. I'll shut up now and stop babbling on. Thanks.

first off m7s are known for being soft on the bottom end as it is. twin pipes don't help, they're more for top end. a good single is much better for low end power. after a few years screwin with mine i got it to where it will get up and go as good as any poo or doo, and backshift and on and off the throttle tree type riding is ten times better than the basically stock m7s i ride with. i run an rkt recut stock head, speedwerx single/slp can, 55/65 gears, 10.4" stock compression style secondary with speedwerx black/orange H5 alloy spring, stock yellow/white cat spring in the primary with cutler adjustable 60 gram base weights set to ~66 grams with the tips fully loaded. i ride 6-9000 ft so you may need a bit more weight in the primary for the 4000 ft. my sled pulls 8100 rpms all day long, which is a bit more than the m7 is supposed to peak at but my sled likes it. this is the best setup i've tried and i've rode this sled ince '06 so i've had plenty of time to try stuff.
