1995 XP 951 Project: Test ride without seat.

Short video test running the 95XP 951 without the seat. Seems to shake badly at low rpms/idle..but smooths out at higher rpms. EDIT: Eventually pulled the engine and tore it apart with the help of my friend Josh. We discovered the crank was marked and timed wrong. Had to replace the balance shaft and then Josh got it timed correctly. It's been running great since.
