Fontyyy (the facts and figures man) has a sharp eye. The right cylinder is NSR250 and the left is NSR150. The VHM head is RGV for sure. Note that it is a 5 stud mounting whereas the NSR150 is 6. Possible that your average Joe might not notice this, but that same everage Joe might find it a little tricky to fit a square peg in a round hole.
The piston "looks" smaller than the bore. Can't confirm this without the parts in hand, but looks like it'll be a little bit of a sloppy fit to me! As I say though, this could be the funny angle so not certain there.

How do you bore a cylinder to make it smaller? You'd need 56.6 pistons for a 275cc kit. Now a quick check reveals that Wiseco have 56.5mm pistons, but only in 14 and 16mm pins that I can see. Probably do have 15mm but I just skimmed the catalogue. They have 56mm pistons with 15mm pins but then that would be 268 not 275cc.

I'm a bit lost on this one.....could someone explain

Heads Machined to suit big bore
That makes sense. But that RGV head might leak a bit if you drill an extra hole. Or maybe they fill up the existing holes with filler and redril. Probably easier if they just bought my specific 300cc kit heads that I developed with VHM than try to modify a Suzuki part.

Well, that's me done.
Oh, and Andy, you'll get a go on the 300 next time. That's if I don't blow it up, or crash it at Bira tomorrow
