I was out riding my blaster the other day after i rejetted it ran awesome it was like so much better then before no bogging or anything. Come home wash it and it ran aight after that then i go to ride it again with my buddy and the top range was just garbage dogging so bad but the plug looks good like it should if i shift down i get my rpms back but then as soon as i shift back up its gone im really confused i cleaned my carb i adjusted it and still no change just runs like crap in the upper end and i changed the jet a few times and its the same
