I'm probably stating the obvious, but why not re-engineer your existing barrels?

375 barrels are a one try then scrap for me
For that kind of money I'd want some nice standard ones
I came across a standard 64mm bore pair last week that needed bored to first size
They were £525 then would be another £160 for bore/pistons but that would have been a mint set for £685
They are gone now I'm afraid

And if your studs are buggered I'm sure mutts just got a set sorted for a mate
And I'm talking totally shagged

Also, tuning has moved on on the last 10 years. Old school tuning lifted the revs so peak would be at over 10K revs and this would seriously reduce crank life. It is now possible to get power below 10k.

Tuning by a well known name and in good nick with a tune you want, ie 'fast road' or 'race' etc is fine, but random porting by some unknown... no ta.

I had 375 barrels and heads with the semi hybrid bike, when I bought it. Inlets had been opened up for Pv reed blocks too. The liners were very thin though, and I wasn't keen on rebuilding the engine and using the top end, so I bought standard barrels and used a NOS head that I already had, and sold the 375's on.

Totally missing bits on the barrels Ground out, welded up then machined back If you didn't know... Steve |
