my buddy mark just bought a bbkw/20mm carb and cdi from sik50's and he said darryl told him to run #85 mainjet now I went through getting my jetting dailed in on my own and dont see how a 75 kit would run properly with a 20mm carb with a #85 in it.We are at sea level and he swears it runs perfect.I have had arguments over this with him but what do you expect from a guy mounted a z50r seat on his 03' xr50 Because its "better"lol
