melted the piston on cyl 3, made quite a mess of the cylinder, piston had melted itself into the cylinder wall :/ so i took it to the engine company near to where i live, would not recommend!!! and he said he was confident that can rebore it, he asked me for the choices on piston sizes so i gave him the choices on oversized pistons n he then machined the bores, so now the bore on each cylinder is 0.5mm oversized, & i will now go for 74.5mm pistons?, i didnt know i may have to have the block notched for the rods, but spoke to idrees now & apparently the kit he supplys... wiseco pistons & pec rods...doesnt require the block notching,
