I ended up coming in two more full turns on the power jet. This motor is stout, but really manageable if you treat it with respect.
With the triple clamps sorted, the kit suspension is perfect for the bike and I am really starting to love riding this bike. I'm at my parents this weekend, so I'll try to get a ride video together tomorrow.

Glad to see you got your carb sorted. How crisp is it in comparison to the OEM carb? Did you have to fiddle with the main needle any? Let's see some new videos of it! :mrgreen:
umberto:
It is a lot more crisp than the stock carb. I had to switch from the 5x needle to the 3x needle, and turn the power jet in four turns or so to get it right. Once I got it dialed, it made a huge difference over the stock carb. I think you will be pleased with yours.
I will definitely get some video tomorrow. I'm really pleased with how it's turned out.

Awesome. Just curious - what state do you live in? I haven't tested the Lectron yet, but hopefully the 5-2XL needle will work for my application. Hopefully I get good results like you did!

Bike looks and sounds awesome!

Thank you for the compliments on the bike. It's turned out better than I could have hoped. I will need to address the fuel capacity soon, which is something you might want to consider as well. It goes through a tank in a heartbeat.
I live in Oklahoma City at 1,100 feet above sea level. Where the video was made is in southeastern Oklahoma which ranges from 450 to 2,500 above sea level if we get into the mountains. i hope these settings will work back in OKC, but I may have to make a tiny adjustment to compensate for the extra 700 feet. I'm pretty sure your 5x will work. My motor is bored, and everything I've read says bigger bore motors run a little leaner than stock bores. I could be off on that, but my motor always seemed to like leaner carbs.
