I just bought a set of loaded Spada heads from a wrecker in Australia, they will be shipped direct to Mike Norman at G-Force engine development for porting, flow bench testing and valve job. It's another investment in the old bike but you couldn't ask for anyone better to do the work. With rumours that our 250 and 300 Lightweight classes will be combined next year I'll need a few more ponies :lol:

Scott,

If anyone can get an increase in HP from the VTR Mike is "The Mann".

John, his built engines have typically been in the 38HP RANGE on pump gas. He says most gains are in the heads but I have already lightened the flywheel by 300gr and put in VF500 +1mm pistons.
