Hi Ste, your engine looks spot on, at first i thought it was the after effects of voxhonda's atempt to turbocharge a sohc . R.E exhaust i have machined some of the internal baffle plates on a cnc lathe and was going to try and roll the sheet metal required but a good friend in work (who is mustard at sheetmetalwork) said he would do it for me so as soon as he gets on with it i will post some pictures cheers
