Zuma 50 + E85 & 70cc Kit 2STROKE E85!

2008 Zuma 50 2 Stroke gets converted to E85 and then gets an aftermarket Tecnigas RSII Exhaust and a Stage 6 70cc Big Bore Kit.
Almost 12% whp gains on E85 and then almost 90whp gain with the 70cc kit and the pipe!!

Is this on a fixed gear?

[@74stevedc]

Does it have to be jetted to run e85 or can you swap to pump gas then e85 etc?

[@SouthernSpeedVideos]

Yes, takes about 30% more fuel on average.

[@74stevedc]

What jet size does it run on e85?

@@74stevedc nobody will be able to give you an answer that will work for you. Elevation, temperature, and humidity all affect the tune so it has to be set up for YOUR environment. Start off super rich and work your way down. If you've got a 104 main, start off with a 140 and work your way down to a low 130
