LesterPiglet:
Does anyone have a rough idea of price for reboring my 550? I was looking at those 600cc big bore kits from Japan.

steff750:
last time i done it lester was on a cb750 plus 50 oversize with a local guy to me it cost £80, he bored the barrels to match the pistons not sure how long ago(5-10 is a good(safe) guess)the years are flying by?

Bryanj:
It'l be costly mate as the last 500 rebore i paid for was £110 and you have to double that as they have to bore the block to fit the liners then the liners to fit the pistons

matthewmosse:
I do happen to know a 650 set of barrells will fit streight on, but have yet to actually do more than drop the 650 barrels and head loosely in place, sans pistons. I think it's about £20 - £25 per bore for a streight rebore, and as Brian said, they'll be removing the old liners and machineing etc to fit new ones. If you do decide to go this way if you have a good set of barrels / pistons that dont need work, then I'd suggest keeping them as spares (or selling them on to offet the costs of works) and using a set of barrels with shot bores where if things don't work out to plan you'll still have a good std set. I have a couple of shot barrels (one had a conrod break a liner, others are plain rusty and could probably dig out a set that have good fins but dud bores if you wanted.

Bryanj:
The 650 bore is not much different from the 550, they altered the stroke to up the capacity
