I am really thinking of just turning the jug 180 degrees and having the carb in front no matter how much of a pain it is to reroute the exhaust and redo the cables and fuel lines...

I modified an air cleaner assembly from a Campbell Hausfeld air compressor to fit on my NT carburetor. It is definitely quieter now and has a lower tone to it.
Will post pics if there is any interest in it.

Please do post pics GN. Took me forever to figure out how much sound was coming from the intake.

The rubber muffler works great but is only half of it. (well, the louder half but not by much)

Yeah, noise can be a drawback of having a high-flowing intake.
I used an oilfill vent as an airfilter/intake on one of my bikes, and that thing made all kinds of noise when accelerating!

I've just been riding my bike to and from work lately.

Having problems with second gear. Since gear ratios are very low, I have enough acceleration to skip every other gear.

I bought a card key at my workplace parking structure today. I usually wiggle around the parking entrance arm at the bottom of the steep ramp. My engine has to be tuned well, and gear ratio must be low enough to climb a steep hill. Some of my MB's were not powerful enough to climb the ramp from a dead stop. Luckily, I was able to push my bike into the workplace elevator.

Using the card key will allow me to lift the entrance arm. I will have a running start to ride up the very steep parking ramp.

IBesides my MB's, I will also be commuting to work with a Honda 150cc scooter. Both vehicles are allowed free parking,


Cars and trucks pay $120 monthly. (Visitors pay up to $40 a day.)

Last night, I took the engine off and repainted it with some Black engine enamel. Today I got to put everything back in its place and on the bike and then I'm good for a ride.
