Topic: Boring out a 350F

[Derek B.]

So, I've often read that the CB400 is really just a bored-out 350F with different cosmetic parts.  Does this mean that, with a re-bore, I could install one of these in my 350f?

What else would I have to change?  It appears that NOS pistons and rings for the 350 are becoming unobtainable and would approach the cost of this kit anyway.  True?  Anybody have a source other than David Silver or Western Hills for pistons/rings?

Keep it a 350F and buy a 400F. Then trick it out with the 466cc kit.
