OCS in Winchester wanted 90 Plus Vat per bore.

Thanks V much, polish the windows so u can see me coming 

Barum in Devon.. 150 all in.

Maybe somewhere else trustworthy closer by

Gen1 Hayabussa pistons in Bandit block, 79.00mm to 81.00mm bore

OCS quoted me £450 +VAT and couldn't do it for 2 weeks.

Barum were questioning the bore to piston clearance,saying it would sieze at 0.060 microns. (My bussa pistons measure 80.942mm)

Saunders in Southampton alot more resonable at £63 per bore.

Guess where my block is going?

Seems a fair endorsement for Barum as well

ANY decent boring place will bore the hole to suit the piston and number / mark them to ensure the correct piston stays with the correct hole!

And whilst I know it happens, I don't agreed with using s/hand rings on s/hand pistons in fresh bored barrels as you've no control over ring end gaps unless they are too tight to start with - receipe for smokey engine. Its not a biggie but worth consideration IMO.

Ray Debben? I have had positive past dealings with him and he has a good reputation.

I used OCS in 2020 & whilst they were a little cheaper then, it made me wince a bit. However, their equipment is very modern, they know what they are doing & the honed finish they produced with their diamond tooling was perfect. 

Regarding Barum, I've seen some of their YouTube stuff & they wouldn't get my business ever. Total shambles.
