Restored this HPV/KPV 100 that’s been sitting for 15? Years. Gummed up with residual castor oil and needing a once over.. she’s alive again.

Also needed the carb/throttle linkage spacer which the prototypes are pictured. They will be available soon for your k71/hpv/kpv thru us shortly!

Nothing like a rainy day to work on a k30.

This unit had a bad bottom end rod bearing.
We replaced that along with new case bearings and are doing a dual carb manifold upgrade.
