correct spark resistance

[Frankenstein]

I get it, it is scattered through out the forum along with 10 different opinions on what does and doesn't work.

I'm not sure I've seen any specifics on how to work things out though like porting for example other than jags website to be honest, Like an actual engine build by anyone showing what they did to achieve there claims

i have seen very few vids if any true ones on any one doing over 50 mph although a lot claim it

I understand, again luck of draw can definitely change what's going on, if these were more precisely made, like something from a BMW factory, then being lucky would have very little at all to do with it. The biggest factor for me at least is having a shift kit. Other than that and some basic needs for a 2 stroke and maybe leaning it out a little gets you there. The only problem is the motor can't last very long doing that! Just not in the quality..
