1987 polaris 250 what should compression be

hey everyone, i have a 2001 polaris trailblazer 265 (bored) with a dg pipe and stock clutching... looking to see what input as to a clutch kit for the primary clutch..
I used to be a big snowmobiler and of course i rode nothing but polaris and what i can remember i always used a yellow spring with M10 weights in my clutch (primary) that set up made it grab around 7100rpm which is obv way to much for my fourwheeler..... dose anyone have a cheap dose of advice for me?

Thanks for the time- Chris

the stock spring on these have 0 starting engagement pressure (blue/green) i put a Brite Green EPI spring (18lbs) in my Scram500 cause i wanted to maintain the low-end torque that its famous for.now my 250 has a red EPI spring(27lbs?) which is two overstock which i think is perfect for mine(revs another grand off the line).now you also put the secondary spring tighter in 2-2 mode and its a Rabid Chainsaw!!
