What about building up the shaft using thermal powder coating, or hard Chrome, then grind it to correct press fit?

It is really a bit weird that the rather wheelie prone RDs did not have them :)
Quote from: Gil Gallad on April 03, 2024, 07:44:28 AMdefinitely iron barrels, teazer. after talking to uncle ron at fahron this morning i asked him about squish, as obviously the 550 doesn't have squish bands. he reckoned it was an easy fix, just machine the heads out to accommodate the oversized pistons, then reprofile the combustion chambers to get the compression ratio right. mine of information that old lad isGil, when you start that project, it would be interesting to know cylinder spacing (C-C) and cylinder stud spacing.
cheers, gil.
p.s. ron isn't doing bad, he still works 6 days a week and he was 78 last month. hope i last that long

Quote from: m in sc on March 31, 2024, 09:35:36 PMid go to 62 leave a bit of wiggle room and have at it w the 550 cyls.. but the tranfser ports are dismal. you'd have to add a boost port or 2 and machine the windows in the pistons but would prob be ok. the reeded h2 i had was around 88-89 rwhp. (and extremely rideable).Yes, the Suzuki 380/550/750 transfer ports were the reason for me wondering about this in the first place. I do not even have a GT550, but I somehow always thought they looked good.
