5.60 Gen 1 set up and , motor suggestions.

I would build something that runs faster than 5.60 like a 1507. You can PM me and I'll give you my email

I've got a 1507 , that has a spun main bearing now. The crank is a weld up. 😕

1507 and no 5.60? What are you looking for help with?

Set up tips , maybe

Is it hand clutch? Do you have extended wheelbase, Airshifter, strapped front end, aftermarket electronics (power commander) any mods done to motor? Is it going to be track only bike? Would you be interested in installing a small dry shot?

Hand clutch, 64 in , slammed front and back, power commander, motor will be 1441 , and yes track only

Sounds like you are well on your way. Little short in the wheelbase - work on your clutch hand. Only recommending small (40) shot of nos to compensate for a bad launch if you are in competition. Air shifter a must. You can put bike on a huge diet if track only. 99 Busa aluminum subframe is a big start.
