It has an Autolite 275 spark plug in there now. They gave me that at the store and said its the same thing as the NGK Bp4hs I originally had in.
It had a 58 jet in originally
I put the high flow air filter on and upjetted to a 64 (figuring would be rich)
Then put the techno boss pipe on it and took it up to a 66 jet, which is where i'm currently at.
I checked for air leaks and didn't find any (near the intake and exhaust [no exhaust gasket]) -should i check other places?
It sounds like it's running fine. Smooth consistent sound throughout the throttle range.
At the top end (wot) there is little pinging noises.(natural in 2 strokes im told /hope?) Also it seems like it wants to go faster but is being held back at WOT.
It seems that if the entire insulator was the color of the one brown spot it would be good, I just worry because it's only "coffee brown" on half of my plug. Should I just let it color in? (pic attached again)
I appreciate all the advice!
thank you all
