So... here is what we know.
The mechanical fuel pump was too small for the CR500.
The pipe was cracked.
The muffler was under packed.
All that conspired to lean it to the max.
We have it running great now.
Wheelies are amazing
But, we feel that a different combustion shape and squish band cut will help redirect the intake charge and help richen the mixture.
Also, the addition of a reed spacer will help things along.
So, we have a few more mods to make.
We played with some different carbs...
The 41mm carb worked great up top but due to the slide having a air gap along the side we just couldn't get the idle to work as we wanted.
So, it is what it is... Quick and powerful but there is more there to be had.
