Why did you go down from a 120 to a 110 jet? I wish I knew more about jetting and carbs.

[@Black66]

Check out the carburetor tuning videos. kzbin.info/www/bejne/emavaX-qqMaBlck

[@lazyYTR]

I just change the jet to the same one you put didn't pick up any speed reason why

[@Black66]

My jetting will not be the same as your jetting. No one's jetting will be the same because of different altitudes, different engine mods, etc. I live at 3700-foot level. I tend to get away with a smaller jet than a person let's say down at 700-foot level. There is no one size fits all jet. Thanks for watching the videos!

[@luiscastillo3549]

@Black66 I'm having trouble getting my mini bike get to the same speed as yours. At most, I'm touching 36mph. I have to exact same mods your bike has at that moment. the only differences I see is my header pipe is the one that goes underneath the seat and out on the right side of the bike. And i have the crankcase breather filter on mine. Any tips please

[@Black66]

There are so many variables. Rider weight , elevation etc,its hard to compare one bike from another Check out the CT200U-EX playlist. There are many part combos one there to get you to the speed you want to be at.

[@Black66]

Make sure you have the carb bolted to the manifold correctly? If you have the carb off the bike you can look down the manifold to make sure its in alignment . If the o ring is leaking between the carb and manifold, it wont run right. That's one of the most common reason they don't run right when first installed. leaks

I’ve got the same bike about a month ago. What’s crazy is I’m doin a top speed of 39 at the moment. All I’ve done is remove the throttle limiting screw and I moved the black governor spring to the 2nd to last hole on the governor arm coming out of the motor. I weigh 215 and it’s cruisin.
