Moped Army

PLUG
Having ridden it a bit more (about 30 miles, I'm guessing), I'm confident that the engine temperature is ok. I've had no problems, and the plug is starting to color (see attachment). VERDICT: The bike runs great on the new pipe even with no modifications made to the stock airbox and carb.

HUM
I was worried this had soimething to do with the engine overheating, but I've abandoned that theory. I think it has something to do with metal vibrating somewhere in the machine. VERDICT: Not going to worry about it.

ARMS
The unicycle arms were out of stock at the distrubutor, so I picked up some moped arms from 1977 Mopeds. I'm having difficulty with that shop, but the arms are perfect. The arm no longer comes near the pipe.

So that concludes my simple installation of the Sito Plus pipe. I picked up 5mph and more power in general. I now get 20 - 25 mph on hills, which is a big improvement. Off the line the bike still needs improvement, I have to pedal start or push off. Hopefully upjetting and increasing airflow will help with that.

Next, I'll start messing around with increasing my jet size and air flow.
