On mine I put in the EPI wet clutch springs (from the mudder kit), stock weights (16g I believe) and the orange spring. Worked real well. Lost a bit on top end but would still hang with the stock 700 Grizzlys.
i dont think your gonna find a kit to suit your needs. most likely just peices of different ones that you will compile into one just for you. the way i see it once you get your wet clutch dialled in its like clutchin a sled: trial and error. time consuming but i think its worth the time. i just put the mudder kit ion my 03 griz and with the chip, pipe, and 27's its perfect! which is wierd cuz the kit is supposed to be for 28's and up so yeah.
