Im getting around to putting my ski back together with my new to me 8mil 862. Is there anyone running a similar motor that wouldn't mind posting their setup? Mainly carbs, ignition and exhaust.

Also on another note, how is the tech support when you buy a powerfactor exhaust? Will they be able to give me a suggested total loss curve, and starting point for jetting? I contacted LPW,(who built the motor) and he really couldnt tell me much about setting it up for a PF- but if I wanted to run a b pipe he could give me all the info I need.

On one of my Cast Dasa motors which is 8mm stroke 81mm bore with b pipe ltd chamber has 140 hi. 130 LO , Novi 48s on Dasa manifold with VF2s. 2.3 ns and 115 springs. I would start with a 150 hi jet and work down from there. It's easy to figure out if it's to rich.
This jetting on t his motor will change this week because motor is getting 85mm pistons . May go up 1 size or two Cylinder is also getting LO profile P.V. Update , and will be installing MSD T.L. , going from stock w/ enhancer.
W I'll also be doing back to back comparison with 140 mag vs 144 mag pumps , as well as novi 44 vs novi 48 carbs

Novi 48s ("D" design) with prök filters on boyesen manifold with rad valves, 120 Hi, 130 Lo, 2.0ns and 95 springs (I think 115 or 117.5 on high jet will work too because i'm a little rich, but just a little)
