Can't run a stock air box.
Can't hit WOT+black plug= far too rich. Install an open-element filter and block off the egr port.

thanks all,
so still haven't given the nitro 50 more thought, but i did start it up recently and it still smokes pretty bad - really thinking the rings are shot. on the nitro 150 front, i have this random issue where on decelerating from a constant 60 kph to slow down, i get a random "backfire". Only happens sometimes... thoughts? thanks! |

Big difference between a backfire and a miss BUT if it makes you feel any better every single cylinder (thumper) vehicle I have ever owned misses/backfires/sputters or other weird noises when slowing down. Mostly 4 strokes 125cc and up that use carbs, but my Burgman 200 does it and its EFI. Don't sweat it unless it gets really bad/constant, thats usually a sign of a air leak in the system (Honda Helix carb mount comes to mind).
