First MB build.
I took apart my new 66cc from RAW Motors to do the recomended mods for reliability. I expected it to have 8M studs, only has 6M. Since I will be buying new grade 8.8 studs, should I upgrade to 8M?
The other thing I noticed, the exhaust pipe tube is smaller the the exhaust port. Worse still, the pipe flange is smaller than the tube! I'm going to open up the flange to the same size as the pipe and taper the flange a bit to help "funnel" the gasses towards the pipe. Anything wrong with this?
Lastly, why is the intake port smaller than the exhaust? This is the opposite of a 4stoker.
