Clutch Set-up Advice

[Todddob]

1999 SRX 700. So i've pulled out my stock 121" skid and bought a Venture 136" skid w/ 1 1/4" ripsaw. What clutching and gearing do you guys recommend? I am totally new but this but this is what i was told by the guy i bought the skid from that has built 3 SRX's. 8BV00 weight, 4.5g rivets, orange/silver/orange primary spring, 49/48/41 helix, silver secondary, 21t and drop one tooth on front chaincase gear(is that the little gear or big one).

21 gear is the small upper one. 8bu,s work great if you don,t need backshift
sounds like a good set up
