do cb350 four overbore kits exist?

[fred1090]

I'm about to trade for a cb 350 four 72 and intend to turn it into a cafe bike. I see the 836 cc kits have a few companies producing them for the 750s and wondered if anyone knows if there is a production kit or if this would need to go to a custom shop.

I suppose fitting a CB400F engine will give you what you'll want w/ a six speed trans to boot

These guys have a decent reputation, they make a 836 kit that seems to have good reviews. They have a couple of oversizes for 350F

fred,
The overbore pistons that you're considering,are they for a problem you're having w/ your cylinders being worn? or do you just want lot's more power ?

Guys, as in every other thread I've read, this is so far a knowledgable and very friendly response. I appreciate it.

Bootsey, exactly, I was thinking overbore new cam and port it. I have ridden dirt bikes (honda exclusively) since I was 11. and this seems like a fun project to get reassembled/running and then upgrade for more experience.

grcamma I am trading for this bike. guy has info showing he had it insured last summer, but it was taken down partially to do a cafe.carbs are in a box. once I get it home i have no clue if the intake ports were sealed properly if they are then this should be a clean up, paint, a few new parts project. if the POs "mechanic" did screw the engine the engine upgrade happens first not last.

thanks again for your time guys, I spent a half hour looking last night. didn't think to look on australian ebay!
