4mil cub duner

[252wheelieking]

I am building a 4mil cub duner & wanted some opinions on what parts I should buy to make this a nice duner. I mostly ride wide open fields, paths & backroads where I live. The only parts I have brought are Hot Rods 4mm crank, 421 cub & 22cc domes. I had plan on using the bolt-on parts from my stock cylinder engine with this 421 cub duner build. I already have VF-2's, SB IF Shearers, Chariot Coolhead, advance timing plate, Boss Racing intake, 34mm PJ's, K&N filter pods, Driveline clutch kit, modded shift star, & shift pro kit. This is my first time setting up a cub mono block, so all help is needed including fuel & timing for this set-up. I know I need a billet basket, billet impeller & 68mm blaster pistons, are there any other parts needed or parts that you guys would replace to make this a better 421 duner? Thanks in advance Reek
