light or heavy?

So I have been trying out a lightened main gear and a stock weight main gear. I found with the lightened main gear that i had a dead spot from 30-47mph till i hit the power band. After i put the stock weight main gear  on i found that I had better performance all around. even had a bit better take off. the only test i did with the stock weight flywheel was one yesterday where i had the flywheel keep slipping and today where i forgot to turn my pet cock on and ran outta gas a mile away from home and had to push it to the house. But on the way i stopped to talk to a nice older couple about my moped. The older guy owns a corvette and ever like 5 years from the 80's he traded his vette in for the newer model one.

70cc's again yay

So I rebuild my maxi's 70cc motor. I did gas porting on the piston other then that its all the piston and cylinder has not been touched. Im waiting on my riffler files to get here something this week to port it. The timing is at 1.8mm. I am running 50:1 with pennzoil marine premium plus.and a 50cc high comp head. I have 18/40 gearing, vm 20 carb, simo pipe. tuned and lightened 2 shoe clutch. videos of what it looks like and what i have done any questions please feel free to ask. By what i know is that im one of the first to do the gas porting on a dyke ring set up. I just wanted to see if it would work and how good. If it works ill think about getting a new piston for it and rock the shit outta her.

simo performance pipe's

So just a little update with out any pic's. so i paid 180 for a simo racing pipe from treats. I like it aot its a really good bike with a killer power band, but there is one thing not many people know about these bikes. They have a restictor in the header right before the chamber. Alot of people do not believe this and even treats say's there is non but with a little work and putting tubingdown the header till it stoped at the same spot and would not go father unless i moved it so it when in the restrictor.
