What's up guys, first actual mini-bike.

My bike is about a week old and of course I'm increasing speed one small easy step at a time. Currently set up as 5" sawtooth tires fr/r. 12t front, 60t rear. Completely stock engine, zip tie on gov to get a few more rpms. So far I have GPS'd the bike at 37mph.

Now to the point. I bought one of those filters and adapters today at a swap meet. I knew it would needed to be rejetted to run at maximum potential but it runs awful. So bad i put the stock stuff back on. Any recommendation on a starter jet for just air filter. My new clutch is here so I know ill squeeze a few mph out of it but I'm sure ill need more power soon. Exhaust will soon follow as time allows.

Thanks

Did It run better when you put the stock parts on it ? Did you have the af adapter on the right way ?
What part of Ky. are you located ?

I installed the filter and it didn't run good. Checked everything out and it was installed with the choke hold bracket on top. I did notice the gasket has a little cutout and the stock box has a relief for this. The adapter did not but the thickness of the gasket should allow air to get in there. Regardless I did a little filing to see if that would help. Still didn't run good. It would run best about 1/2 - 3/4 choke. This is when I put the stock air box back on and took it for a test ride. Runs perfect and actually when I managed my best mph.

I'm up in NKY
