The TP RACE version from PARMAKIT is a super cool high engine! With its diameter of 47.6mm, it does not require machining of the skirt foot (however beware, it is made for long strokes 43mm, so it is necessary to machine the housing to pass the crankshaft in all ways). It uses the same architecture as the Ø50mm racing version with slightly nicer diagrams. The piston is a graphite mono-segment to allow the highest revs, the cylinder head is mounted on O-ring and is studied for better cooling. This remains a very powerful kit to accompany a large carburation, a variable advance ignition, an exhaust for very powerful engine ... To be installed with a 43mm stroke crankshaft 12mm axle 80mm rod without wedge or 85mm rod with 5mm shim!
Optionally we offer you a stage 1 preparation, this preparation is a modification of the channels and the exhaust light by increasing the diagrams and improving the duct, it increases the performance of the cylinder. An improvement in the piston and bottom of the skirt is also included in this modification. Allow a little extra time for this preparation!
