One thing to consider, my bike is a 71 so i had no choice it's kick only. I'm still sorting out six different issues. She has a habbit of running great until I'm in the left turn lane with twelve cars behind me and then she stalls out. With the big bore it can be lots of fun trying to kick her back to life with horns blairing. I hope that by the end of this season that won't be an issue anymore but with old bikes it is something to think about.
