rxx mpm advantages or disad
Been working on my Ski for some time now. I'm specting to hit at least 75.mph top speed . Right now the RX is turning 6,890 rpm. (91 mm bore twin pipes M16 R&D reeds stock rejet carbs skat pump setback 16/24 R&D ride plate and grate. ) The buckshots 50 mm are in the set up but my compression was about 147 psi did'n think the engine will move them so I switch to stock. Last test run the ski stall ,take it out off water and make a compresion test . Resuming I ve ordered a new cranckshaft (using stock one 200 hrs on it and had exes freeplay on the rods) and found that the raves where hitting the pistonrings (there the loos of compression) In the mean time I started reading some other post about twins setup and got me thinking I just only programed the lanyard to my rxx mpem . So I'm planing to set corrected timming on it once had the engine build up again. wil this mpem get me tu run 75 ? with proper engine tunning or do I need like an MSD enhancer or a Microtouch ?
Dean thanks for the tip... Thanks for reading to all...
