had a bit of a problem, i bent the kickstart shaft trying to kick it off, so i have purchased a casa shaft complete with piston from one of their new wide sidecasings , when fitted kickstart splines didnt line up correctly so i decided to install a ramp on the side case, had to slot the holes a bit, and remove some material from one end, but did the trick fine, i obviously had to remove the gearbox backplate and cut the ramp off, a worthwhile modification. this engine does have a real lot of compression so i decided to build a moto gp style roller starter to bump it off with when cold, i added a go kart engine to it instead of an electric motor as its cheaper and more powerful, will add some pics in a bit, gave it a good road test after getting it started with the roller starter and found that it had massive vibrations at about 50 mph in top gear, not ideal, anyway i decided to change the large engine mounting for an old one out of my rb250 and it did the trick, lovely and smooth now, not had it in the powerband yet, ive got to get some miles on it and get it run in before i get it on the dyno, runs very cool about 40 degrees so cooling system is working maybe too well, but very pleased upto now.
