Hi all I thought I'd share my build of my 2010 Yamaha Zuma. This is it current set up Converted to L/C TPR 86cc TPR 44mm stroke crank with 85mm conrod MVT DD19 Inner rotor Vforce3 reed block 28mm PWK Keihin carb Bosch electric water pump Malossi overrange Dr.Pulley HIT clutch S6 433g clutch bell S6 forks Doppler rear shock S6 280mm rotor S6 brake calliper 13inch gyronetics wheels Naked bar conversion with S6 gauges All the case work was done by hand with simple everyday tools. First off you'll need to fill the back of the cases with JB weld where you plan to grind/file. Its very thin here so your going to put holes in the cases if you don't do this step first The idea here is to make a smooth flow path from the intake to the transfers/boost ports You can see the darker spots in the "trench" that's where I broke through the cases and into the JB weld
