I fired up the tanaka today for the first time since last fall. Sorry about poor quality my phone is my only camera. Sounds kinda like an aeroplane in the recording though.
Yes, It is a 2.3 gallon unit off of a...I Don't remember...I was installing an extended on a buddys enduro last year. He left the tank in my garage and it works great on a MAB. Serious mileage and you have like a .3gal reserve by tipping the bike over. I was driving about 180miles (city) before I hit reserve on the original friction drive with a Tanaka 33cc. I am quite a leadfoot and ran pretty much full throttle everywhere I went. It scared me enough that I think 35 is about as fast as I will ever want to go on a MAB. I can't wait to get the chain for the CVT this week though.
