Hi all, been getting on with rebuilding my v4 block. Had to make a jig to hold it in the miller for skimming the tops of the cylinders. Front side is done, now to do the rears. It's taken ages due to other work and also the inverter driving my miller packed in. But at least I know that flycutting does give the flat surface needed, and that clamping a v4 in the machine is a right pain in the backside.
Interesting reading on the carb issues - my bike came with a burnt piston, so once the engine is back together guess what I'll be doing? I want to make one comment though, someone wrote that idle mixture screws djust fuelling up to 4000 rpm - well this isn't true for all conditions. On no load (ie just sitting there opening the throttle) yes, probably true. But on the road, pulling the bike and big fat biker allong 4000 rpm will have the carbs open a whole lot more, hence all the progression holes will be open, even if the needle hasn't lifted? Just my take on it, tell me if I'm wrong?
