My First Motorized Bike

Hi all, some of you have probably seen me floating around the forums a bit, and to all who have helped me in my venture (special shout-out to DAMIEN1307) thank you so so much, I couldn’t have gotten to where I am without y’alls help!

Looks good! Welcome to forum, I've seen you lurking around here for a while.

Oh also I reached a top speed of 47 mph on a flat road

Not to mention when I hit an average of 40-45 mph (my top speed) I four stroke like crazy, like I hit some sort of rev limiter.
I'm running a 68 jet, but in all other RPM ranges it has great throttle response and 2-strokes normally, so it's obviously extremely close to the right jet...should I go for a 67 or 66 jet? A 65 was a touch too lean and didn't give me a strong enough charge

You could be going lean at top speed, they call it something? But instead of 4 stroking your actually going lean. Some of the others might chime in, I'm new to these 2 strokes as well.

It sounds like it's misfiring at full speed, it's kinda weird, but it's definitely 4 stroking. I don't think it's a lean issue, i think it's just a tad too rich at full throttle. I'm wondering if adjusting the needle clip will fix the issue instead of the jet.

Are you using an actual speedometer or bicycle computer? I'm also assuming you're running either a 10:32 or an 11:36 drive ratio?

What bike frame manufacturer/model is that?
