First start after new top end

swapped out my 400 pistons cylinders and head for 440 parts. here is the first start up, not too bad for not having a clue what we were doing when we started lol
Kz 400 first start after 440 swap
carb needs to be tuned now

I like the sound.

that was just open headers, put the mufflers on and fired it up again and they are way too quiet so I think I'm going to try to make some glass packs out of the hacked up stockers that came on the bike
