Bought a 550cbx before my heart attack then later recommisioned it and sold it for a profit for once, always hated the front brakes, you needed a degree in origami to put the front wheel in, i understand there is a good market in exporting back to Japan

Those are questions for the Honda Twins forum, also try comparing parts at cmsnl BUT make sure you look at the correct country parts as they may well very between countries

There are several firms selling piston kits, Dave Silvers has 0.25 os kits BUT nearly all the 500 bolcks i have bored did not clean at o.25 and had to go0.5 due to "barreling"
Cruzin only sell 0.5 and 1.0 as does an English firm i have bought from.
I know Trigger used Cruzin and i have done a few 400 recently using their kits, the us problems i have read about all seem to be 350 four and they are VERY critical on bore to piston clearance.
Cruzin piston kits usually arrive within 8 days and i have had uk parcels take longer

Thats probably due to corrosion, worst one where valve was open, will run for a 2-3000 mile a year fun bike, not good for one used daily and/or hard.
You could rering it and hone but hone may give too big a piston clearance.
Piston kits or rings from cruzinimage in japan, std same price as oversize so you pay extra for rebore and then its as new if you wish

How about just finishing a morgo conversion on a 1961 Bonnie, turning round and seeing 2 piston circlips on top of the gatepost!

Dont know for certain Ash but i do remember a Honda tech rep telling me no Honda valves should be refaced on grinder only lapped in

A Serdi is a big industrial machine like a Bridgeport mill that can replace seats and recut the angles acuratly, not a home tool and only big machine shops have them.
I must admit to never seeing hand cutters in the dealers kit, may have been an early one, all the Honda seats are supposed to be Stellite which is why they say grind with stones.
I know Trigger found a full stone kit some years back and was happy to buy it, dont know if he sold it.
Those valves just look too rusty for me to trust them in everyday use, head comming off would totaly trash the motor

Those valves are not safe to use in my opinion, when i said grinding i meant what oddjob said as in shaped grinding stones not grinding paste and a stick.
To even touch the seats on that head would need a Newway cutter set and sit down before you check the price of a kit, i have one bought at auction, no i wont lend it out, reaso is they have tungsten carbide tips not hss and just for info an ebay advert for a set

Honda valve seats are not suposed to be cut but ground with special kit.
Valves should never be refaced but only replaced
