Thanks for sharing, sounds good 👍🏽😎

[@jmrides777]

No problem 👍

[@SuperTrikeBicycle.]

Nice bike. You should be running 50mph plus with Athena. Make sure you have a good NGK plug and not to much muffler back pressure. Something is definitely holding it back.

[@jmrides777]

Hey thanks for the complement bud. This Athena engine does 60mph up an incline. But, its the crank that is failing now. This crank is either 2 or 3 years old of complete balls out riding. 4 seals so far have been completely torn blown out like torn blown out!

@@jmrides777 if I had it to do over again. I never would have built a chainsaw hybrid or Minarelli. I would have got an old dirt bike motor and put it on my bicycle. Transmission and all. It's not that hard. Plus the quality of Japanese over Chinese lol. And twice the power.

Never had that style carburetor before when you get that bike all dialed in going to be fast for sure thanks for sharing bro ride safe

How was your jog pipe compared to your FMF pipe?? What was the powerband differences?

[@Littleevil9975]

The jog pipe is great, but it’s no comparison to the dirtbike pipe. My KX pipe hits way harder, comes on a lot quicker and seems to last a lot longer of a power band. I would say a big improvement over the jog pipe.

[@jmrides777]

Cool, thanks for the reply. This 70cc 2Fast pipe is a mix of a Dirtbike pipe and a Jog pipe. I'm hoping that it hits hard....

[@Littleevil9975]

You’re welcome bro and that sounds pretty cool. Interested to see how the results are.

[@Op1zilla]

To the sound, it sounds rich Jim, I don't have a smart carb an wish I new the answer to help cause I know it will haul Ass, 👽👍🏻

[@jmrides777]

Hey thanks bud, yeah weird. This set up with the FMF pipe hauls ass.....the 2Fast Pipe.....scratching my head.

[@Op1zilla]

Try turning the thumbwheel left. To lean it out some. Cut back on your intake manifold its to long. Also make sure the carb is leveled 👍

[@jmrides777]

Thanks for the tips.

[@mybikes1970]

What size is the Smart carb? Maybe tech support can help you dial it in. That's how my Phantom 85 runs most of the time but I'm using a Dumb carb lol! Eventually you'll get it running right 👍

[@jmrides777]

28mm. Yeah scratching my head still.
