It's running better and better as I ride so I think it's just growing pains from breaking in. Any sugestions on spark plugs other then the stock china one?
NGK...or Champion CJY8....the stock plugs will suffice but burn up rather quickly....also the CJY8 is shorter...allowing a little more boot clearance is that's an issue....I use NGK's....hotter fire and longer life....hope this helps.....and yep....you're motor is breaking in....after like 3 tanks of gas you'll notice....
