My firend recently rebuilt a MC28 which was a basket case. The barrels were badly damaged but we managed to source a complete MC16 motor. We fitted these barrels and new pistons. On starting all seems fine and revving in neutral is fine. On the road the engine dies
(almost stops) the faster you try to go (under load).
The carbs have been rebuilt using genuine parts from Thailand
It has new Tyga exhausts
Any ideas anyone?
