Dont need a fuel pump. Either way, wheres the rewire?

Zzp mps is easier to find used pulleys for.

Which cam is that? If small, i would run a new stock chain. Unless you intend on degreeing your cam. Then its a can of worms. Jp had issue with wrong chain/gear combination. Unsure if they fixed it.

Looks like its an s2. Unsure if that is worth it over the s1x.

Rollmaster crank gear needs to be machined. Im willing to bet, the jp does as well considering theyre both for autrailian 3800s.
