Hi Guys!
Haven't built anything in a couple year and I finally jumped off the cliff and grabbed this:
Yay!
It's a 39cc watercooled pocket bike motor is the only specs I could find were these......
I know some of those letters and words
So I want to be able to hook this up to my sick bike parts jackshaft kit I have for my 2 stroke ht motor bicycle engine. I know this engine uses a 25h chain, and this is where my problems begin. I found a tritan #25 roller chain 5/8" finished bore sprocket 18t, it's the least teeth I could find that would fit the 5/8 jackshaft and #25 chain. How many teeth on the front pinion gear would I need to get any kind of useful gear ratio? Or I need to find some way to hook this 25h chain to my jackshaft kit
