Xaio has been hard to get a hold of, but I have always been interested in some of the parts he has developed, mainly his 4-1 header and the crankshaft/camshaft pullies, which would make a big difference

there are pull./gears we need on ebay for cores or if anyone has extras, we could also have those made up as well, and give some big gains from what i have read from xaio

idk about the header though, that would be a lot more difficult to have made up

any interest? seems like the underdrive is good to go

why in the world do we have kermit smiles?
