It's a hybrid, meaning the bottom end is a zenoah 230rc, the cylinder is a Chinese clone that's had the head machined off. The cylinder head had 4 transfer ports...these have been port mapped and ever so slightly ported to change the port timing a tiny bit. The head has been replaced with a hemispherical dome head specially calculated to the right volume to run on 95 octane gas/oil mix. The new cc rating is now 28.9cc due to larger bore of new top end. The flywheel has been lightened. The timing has been advanced. Massive dominator tuned expansion chamber. Huge walbro carburetor. Velocity stack. K&N filter. 0.7" drive spindle. Third bearing support added. Chrome fan cover and pull start.



Yes...lost the plot...but everyone needs a hobby eh

You've got talent!
