Gotta go get some sparkplugs tomoro for my bike and wanted to make sure which one i should get. For a runner 172 lump Iv been using BR9ES i think, does that sound right?
Cheers for that tweak. My sparkplugs have been dying since i put the 25mm carb on, always coming out black and wet. Running on the airbox with a malossi sponge. Im thinking its either too rich, or getting too much oil. Any ideas?
drop the needle to the top notch, wind the idle out a turn and drop the jet.. (idle mix is around 2 turns out from fully in)
