i did the filter off,filter1/3 covered with tape test and saw no significant change from one to the other.my mods are a fmf powercore 4,142dyno main,3 notch from top on needle,& uni filter with lid on.bike seems to run alot stronger with new mods,but i just want to make sure i am not running lean.any input would be great> thanks

 

somebody please give me some info!!!!!pretty please

 

what does your plug say? if you feel the power and the plug looks like a brown paper bag the its probably good.

 

everyone says with todays gasoline it is impossible to get a accurate plug reading.is this true?

I'm just curious, what do you mean by this? What is the test for and what are you supposed to look for when you do it?
