To all who are interested in the proper oil to use in the Moki's. I spoke with Julian and he has observed that a high percentage of repairs where RedLine was used showed galling and scuffing in the crankshaft / master rod area. He was willing to talk and carefully explain the issue. I looked back in my "oil history" and I was using Amsoil Interceptor. I have ordered the Dominator version. Even though my engines seem to be perfect I decided to make the switch.
Larry Fitch; The OS feeler gauges for their 4 strokes work quite well on the Moki valves. Also look back in the not too old history on this thread for the information you need on the fuel pump. -Tom
