Need a little advice, I keep going bck and forth on running the SLP's I have in my garage soley based on reliability and low snow, it needs to run throughout the year, but SLP's jetting has been known to be damn near spot on, sooooo
If I have a fix powersports clutch kit that is currently over revving on the single pipe to 8900 rpms, what parts would I need to make it work with the SLP reccomendations which are attached.
Also would 22/38 gearing be stock? That is thier reccomendation as well.
Thanks guys I'm getting antcy and need a project! ha ha

One other newb question if I install the pipes and she revs perfect to 8900 I'm set right? Or do the proper weights effect upshifting and such and rev limit alone is not the ONLY thing to be looked at? Thanks!
Different weight #'s have different force curve's. Some pull harder on the bottom, other's more so on the top.
The goal is to get a straight shift, so the rpm's stay at peak power from low all the way through to the top end. Once you have that, then play with the secondary for snow conditions, back shift, type of riding, etc.
SlP's work best in the 8700-8900 range, with the sweet spot being 8700-8800. On mine the power starts to fall off above 9000.
I would start with SLP's clutch spec's first, then fine tune from there. You may find it want's to over-rev on the upper end with 8EK weight's. If so try moving some of the rivit weight from the heel to the tip.
If you still see an over-rev on the upper end, with the rpm's ok down low. You may want to try some 8DN-10 weight's, used on mountain Viper's and some SRX's. They have a flatter force curve then the 8EK's, and are with'n 1 gram in weight to the 8EK.

Thanks for you patience guys, I'm getting there LOL!
Is that a part number for a set or each weight? you need 3 total weights in a set right? Thanks again!

Yep, each weight. It would be a good idea to pick up several different sizes of rivit's too. They're cheap, and it's handy to have a wide selection to pick from, in the tool box! I try to have at least 3 of each size in my tuning box.

8DN-20's work very well with SLPs also.

the 8DN weights are real good all around weights. Have a lot of pull all the way through, not flat anywhere.

8DN-20 weights work excellent.
