Ok I am still trying to get my 2004 f-7 efi sno-pro dialed in.Ever since started messin with the clutches I have opened up a can of worms. I am wasting valuable riding time so I am turning to you guys for help again. I am ordering a new clutch kit (black magic heartthrob). it is an elevation kit 4-8000 feet. it comes with 59 gram weights. Does this sound like it gonna work? I am afraid it's gonna be too light on the weights and I am going to over rev the damn thing, but thats what techs at Black magic are telling me there elevation kit comes with 59 gram wts, and they are reccomending it to me. Its actually an 03 kit but they are sending me some shims and are telling me not too worry that it will be fine.Black Magic is a good company right?There technicians should know there stuff right?I am still worried because right now I am running 64 gram weights but am having shifting troubles cuz its a sea level clutch kit.Will this elevation kit with the lighter weights work for me you think?I mean a sea level kit compared to a higher elevation kit is gonna have differant spring tensions correct? So If they are sending 59 gram weights with this kit, the springs are probably a differant tension on there elevation kit versus my old sea level kit with 64 gram weights correct?I guess what I'm asking is are all kits differant. Right now my 64 gram weights enable me to rev the motor to around 7800-8000 rpms, but its a sea level kit. I am worried that going down to 59 will be tooo light. Since it's an altitude kit will these lighter weights be ok for my motor?? Thanks fellers..
