Haven't tried the sprocket adapter yet but bought one to upgrade an older in frame 4 stroke build. It's my understanding that they can be adjusted to tweak chain alignment. That alone would have to be a real plus. I got the TKOMOTO unit off ebay because the clamp area is an inch wide. Hoping that will keep it from slipping. Less than 40 bucks I think. Anyway, thanks for cutting me some slack! I DID go to the intake, exhaust, etc. area and got my question answered concerning the tuned pipes AFTER blowing off here! lol Take care fellas
