The piston order has to wait until my block comes back from re-boring (I wish I'd measured a few things as I tore it down)
I finally found the "early" model cams I've been after, with buggerall overlap, and more suited to the blown application,these will pull the power down a 1000 rpm or so, allowing for a bit less blower under drive (if needed) and more boost, and a tad more valve / piston clearance.
Stock head gasket is .3mm thick, the new copper one will be .5mm, as much extra as I can use without upsetting the backlash of the gear driven cams.
I'm planning 10/1 for the forged pistons (down from 11.7) which should still give me 16.7/1 with 10 lb boost (I'm trusting my night shift memory there)
Two Bob Engineering (myself & co-builder Wilso) are off down to Melbourne next week to pick up a spare bottom end we were given 6 mnths back, Doc Goggles used his light coloured molskins to soak up its viscous vomit when removing it from a car trunk
We are also picking up another '87 CBR250 r in a barter deal with a couple of leading link sidecar front ends (hopefully) Wilso may fit as a favour.
While on a shopping frenzy, we will get a Honda NSR 150 single sided swingarm and wheel, (maybe 2 ?) for "sidecar stock"
I'll be broke once I get the pistons, but that's LSR, and it saves "wasting" money on things like food and booze eh !
