Spifire tuning tips.

Post by Jingles »

I don't whant your race secrets, only some ideas were to start. Any tips on tuning the engines or clutches would be great. I got 3 spits, one Kawi with Mic. throttle plate carb.
One Kohler with the same carb, and one Kohler with a Mic. round slide carb. The latter
is the fastest one, yet it is the oldest, most abused machine in the bunch. Since I don't have a dyno, and there's no snow here yet, I would really like some tuning tips to save me a lot of experimentation. I would really love to find an appropriate dual carb setup,
fully realizing that i would require porting and pipes to make any difference. Help?
Ron.
