hey, this is NightBiker07. my regular account is having issues? talking to admins about it now.
anyway, i got my 250r back together, with a 300r kit, and a 38mm mikuni to feed it.
the bike idles great, and runs good.
when i ease through the throttle, around 1/2 throttle, it bogs/sputters(not sure which) but if i hammer the throttle, it wails straight to the top, with no problems at all. if i go richer on the main jet, it constantly sputters on anything above 1/3 throttle, and smokes like a mosquito fogger. anything leaner, and it runs HOT (around 280 degrees)
the curent MAIN jet lets it run decent everywhere, but as i said, if the throttle is not HAMMERED, it gets a funny bog/sputter at/around half throttle, and WILL NOT come out of it unless you lets it come back to an idle and hammer it. Does not seem to have a plug fouling problem either. in fact, the plug gets a black-ish tint to ONLY the core and electrodes, the rest of the plug stays fairly clean. runs at around 240 degrees, and about 350 on the headpipe right on the jug. (cousins big red headpipe runs in excess of 500 degrees, and cylinder temp hovers around that of mine as well)
also, the thing is a BEAR to start, not because i cant kick it, but i gotta kick it ALOT, and use starting fluid when i get shitfull of kicking it.
i adjusted the needle some, but have not played with it a whole lot. i figured i would get some pointers before messing around too much more.
