Jetting

isclaimer: All sleds will run differently even with the same mods. Read your plugs and piston wash to determine if you're running safe. Get EGTs if you can. Speedwerk probably has some jetting recommendations if you contact them.

Are you going with twin pipes? What CR is the head? Probably be safe to start off with 410 MAG 420 PTO, Jet Needle 4th clip.

Edit to add: If you're going with twin pipes they run pretty lean mid-range. If you're trail riding make sure to vary your rpms(don't hold it mid throttle or you're asking for problems).

Cllutching

Probably throw some 70 gram weights in there.
