The bike ripped. At the bottom of a long hill I snicked into second and wound it up to the redline like a dyno run...it performed almost flawlessly....a little reluctant to get off 2000rpm mark but it was a clean pull to the redline. By the second run a neighbor was out in his front yard shaking his fist at me in a 'get off of my lawn' style. Mental note to move my test track. Such a perfect long slope though, but was just as well, might be running lean without the 'box.
Question was: is it the PGM or the airbox? I decided a decent compromise would be to sacrifice my spare airbox top and punch in four of those 20mm holes as depicted at the very bottom of here: https://nsr-world.com/nsr250r-tuning/nsr250r-carb-tuning/
Put it all back together and the bike wasn't as happy. Was fine once it hit the powerband and it would pull well to the redline but there was a lot of indecisive stuttering leading up to it....figure tomorrow I'll take the top off completely and see what happens. Why's this happening? Running too rich and losing the 'box leans it out? Not very likely. Or maybe I'm crimping some of the carb plumbing with the airbox in place? All i know is that I got a taste today of how the bike should be and it was great- just need it to be like that most days.
Here it is in testing mode.....only thing (legally) missing is the rear light...but I have one of them mercury switch brake lights on the helmet...so there's that.
Weapons Of Choice.
