Which lines did you guys that made the conversion use? The XCR uses a 3/8" line where the XC uses a 1/4" line. I can get the 1/4" line to fit the XCR oil pump but should I go bump up the oil ratio on the pump? Right now I'm about one line thickness above the alignment mark using a 1/4" line on the 3/8" pump. In theory using a 3/8" fuel line and 1/4" oil line should work for the richest oil ratio the engine runs at but a 1/4" line doesn't flow as fast as a 3/8" line. I'm just curious to hear what others have done. I used to have it set really rich and it didn't foul plugs but I think it will run better with a little less oil.
