Thanks for all your reply's I think I will go with a single WES pipe, I have matched the ports fibre reeds
straight inlet rubber and a modified airbox The bore is still on standard I may look for another barrel and
bore out 2mm oversize. I also run a whitehawk 200 which I have had a oko on but the standard carb does perform well and retain the bottom end . I run electronic ignition on the 200 , Has anybody got the points system
working well 0n a 175 ??
