The idea behind the engine was for 2000cc car hill climb class. But you guys in the USA love big things. I've run the motor at 2 drag events late last year on a 4 inch over but not slammed bike, just a test bed. I ran 9.7/157 with a 1.9 60' but couldn't put the power down, but it was good fun. The spec was std injecter bodies with bigger injecters. std head with .398/.375 Web cams, 14:1 on super unleaded 97 ron pump fuel. it made 240 rwbhp at 8000, 160lb/ft at 6000. I pulled it apart and everything looks fine. I will be rebuilding it with 440/395 cams, 2 mm over inlets and 1mm over exhausts and up the compression some more. plus some oversize injector bodies and a bigger bore pipe. Most of its done but customers keep getting in the way, I have to earn money to play I suppose. By the way the bore and rods centres are 93.5mm, with the long rods the pistons don't come into the crankcase so that helps on the bore size. I will be selling kits consisting of block, crank, rods, pistons, cylinder studs, primary drive and clutch basket, so you can get your tuning guro's to build one if you wish.
