I built the golden eagle kit and that's what it comes with thank you but I'm wanting to do a different thing and the belt is narrow on the drive ring with the golden eagle kit. Plus the kit with the GX 35 a motor was a little over $700! IF I CAN FIGURE OUT HOW TO GET A DRIVE SYSTEM FROM THE SHAFT TO THE DRIVE RING USING A BELT. then I'LL BE ALL SET. WANT TO USE THE Hausheng ENGINE BECAUSE I'VE HEARD IT'S THE very good.
Sorry about the lettering my phone is acting up. in a perfect world I could mount a 49cc in the frame and run a belt to the back wheel and have belt drive whizzer makes a drive pulley shreve for the rear wheel that is wider and heavier than the golden Eagle drive ring ) pulley.
