the plug is lookin good. that kinda chocolate brown color. although i'm not entirely sure what the jet is. also i'm riding on 29'' wheels. will i get any benefit from switching to a 36 or 38 tooth sprocket. i'm not lookin for break neck speeds but more so to help my cruising speed and not feel like the engine is gonna blow up.
its pirates pk-80 slant head and yeah it kicks ass. i started with a strait head on an old 26''schwinn and it was what i expected but the pk-80 had balls to no tomorrow even on 29'' wheels and no bolt on's. so if i change out the main jet would i still have problems with the taller gearing? or is it best just left alone (the gearing)
