dont mini stroke a corsa. the port timing is much more ideal with a stock stroke crank.

I would trust in Baka, he has never turned me wrong. He knows more about the AF16 than most will ever want to.

True that. No matter what the endeavor, competition brings out the very best. And you learn less when you're winning than when you're sweeping up the pieces. I suspect Baka-san has paid his dues with a good share of both. Respect.

the 50-51 bores like the ruima is made to run with a mini stroke crank.plus your going up in cc so the torque should increase more than running a 72 cylinder. try 8.44 gears or 9 to1 gears if you want the front to come up easier.the dd50 us a heavy bike.

@baka what kind gear oil you use?
Re: polini 72 mini stroker help

10w40 which is what honda recommends. I do add some if the lucas oil heavy duty stabilizer that comes in the tall white bottle. it makes the oil a little tackey so that the oil sticks to the gears better.
