New member & first time builder, finally off lurker status. I’ve got a stock 80cc with a bofeng carb stock jet #70 & clip one up from the middle (I’m pretty much at sea level) and a mz65 clone pipe (bike berry deluxe). 40tooth on a 26” wheel. My top speed and max rpm so far have been 31mph & 6400rpm (at least that’s the highest I saw). **Question Time** My plug so far is a dry milk chocolate brown (NGK BR6HS) and I can’t figure out if I should richen in up plug wise since I have a pretty dang smooth rpm curve with 4 stroking once warmed up with where my clip is set and the motor doesn’t seem crazy hot. The picture under flash is very harsh but gives you a worst case look at the plug. Warm motor was shut off at wide open throttle before these pictures.
Don’t feel like I really understand how to compare my plugs to a chart just right.
Lemme know what y’all thing and what other details should be included
