How much overbore can a 350f block take?

Calm down and sail on
I need some advice on the overboring, I know the 350 is over at 48mm and the 400F is stock at 52(i think), would the 350 block handle that much without major problems? I don't plan on racing it I just want it "better" than stock...

Is this possible to do that much safely on that block or should I just do the normal 2 over and be done with it? Like I said km not racing it so duration is preerred.

Also, what about valves? If I do the normal 2 over what can be done about the valves to get a step up in performance? Bigger vlaves? Better metal?

eh why not off that 350 lump and just build a 400f?

the 400F is about a million times better as far as bikes go.
Fair bit more power stock. stronger, has a 6 speed.
 
Thanks scrog I'll look into him.. and surfly, I am starting to lean to a 400f that and I didn't know it had a six. What would a 400f power train cost roughly do you know?

I know the parts on eBay are pretty pricey but engine work is too.. I saw heads for about 200 a few months ago...

ummmm it depends. might get lucky and find a whole bike cheap....or not
They are kinda collectable and honda didnt make them for that long.....but its a honda so its not rare.

All around the 400 is a much much better bike.
it also has alot more support with parts.

The 350F has alot of things that are NLA
 
Got ya, so you're saying I should just get a 400f or just get a 400f engine to put into my 350f frame? Cause, if I'm changing the suspension and putting new wheels on it, is the 400f frame that much better than mine? I know the frame is the backbone so I'm just curious. The chances of me finding a whole 400 is way slimmer than getting a 400 engine..
