IM THINKING ABOUT GETTING ONE OF THOSE LM1s

trying to adjust carbs without anything like that is just pure guesswork....or LOTS OF WORK AND TIME ....reading sparkplugs and stuff....which I dont really have time for...

I just wanna be sure Im starting with a good baseline and then tuning from there....

I will start with stock jetted and setup carbs. then go from there.

I think those LM1s are no longer available, and now there is a new version out.....but I heard abhout people saying that their new version is no good?
