Zuma Athena Race 70cc BBK install : Day One building the motor
I went into this with a better idea of what I am going to do. I watched a few videos including one with a Zuma JOG motor off of RollingWrench

I also did some research with ScooterTunning.Ca and 49ccScoot forums. Great Help. Watch my adventure of a new 2T novice take apart scooter and try to make it faster.

The multiple gaskets/shims are so that you can adjust cylinder height to get proper squish, transfer port, and exhaust port durations and measurements . To get proper operation and maximum efficiency from these kits, you cannot just bolt and and go.

Always put a shop rag in the crankcase cavity so the wrist pin or anything doesn't fall into the crankcase.

Today I took a carb off and dropped a nut into the motor. Amen to magnets ! I will do that from now on

Good job 2 strokes are nice and easy less parts just do a proper break in for the piston and sleeve so you don’t burn it up.

I plan to :) my first instinct is to rip rip and run! Thanks - two strokes are so easy

Did you have to change the carb or do anything different with the carb like different jets since it would need more fuel for the 70cc?

Stock one for now and runs well with it. Probably could use a hotter plug.

@johncoscia5258 4 жыл бұрын

No No , Get or make a degree wheel , bolt it to the end of the crankshaft and turn clockwise noting the degrees open the exhaust port is a turn more for the transfers [inlet] same deal . Its not hard but you need to know durations or the degrees for both ports opened which change with more or less base gaskets or as you said shims ,spacers were included . Also B.D.C of the pistol should be level enough to the bottom ports opening . Not enough information by the way from dealers and me so see 90GTVert channel .lol

@roywalls5595 5 жыл бұрын

@@SmallEngineVelocity yes

@SmallEngineVelocity 5 жыл бұрын

No, since the belt needs to slide up and down the drive face to change gear ratio. I’m sure there is some creative way to do it but far as I know the answer is no.
