Everyone said the carb was probably just dirty, so I pulled it and cleaned it. Looked good except the pilot jet screw had some gunk around the base of it (looked like a destroyed o-ring) Cleaned that and the holes at the end of it and also pulled all the othere things and made sure they were clean and open (they all were). When I first saw the dirty pilot jet screw, I was thinking great... that has to be the problem.
Put the bike back together, fired it right up made a few adjustments to the fuel screw and it seemed to run better. I put on some new radiators and took it for ride and it seemed to be right back where I started. It would fire up nice, I could twist the throttle hard and it would sound good.
I took it for ride about a week later and it ran rough (still firing right up and the throttle twisting hard was good) Took it out and lots of hesitation. Pulled it back into the garage and completely removed the carb this time (throttle cables, etc...) took it all apart, top section etc. just to see if anything looked dirty. It looked fine, but this time I also purchased a fuel mixture screw so I put everything back together and fired it up. Started right up, sounds good, twist the throttle good, I drive down the road a little and it feels good (like how it was before all this) Granted I am only in first and second. (when I say good also, I mean the thing has always had little backfiring on decel, but zero hesitation when twisting the throttle) I wait a little later for it to get dark and take it out on the back roads so I could get up into the gears more.
Bike seemed to be good. Riding good through the neighborhood, first and second. Pull out onto the road and take off, first, second, third... and then the hesitation..... I let off the gas and it just stalled, I dropped the clutch if fired back up but then ride back off as I coasted to the side of the road. (now I am sitting there on the side of the road with all the cars passing me, hoping one of them isn't a cop wondering why I am riding it on the road). I tried to start it, but got nothing. After about 2 minutes of trying that, I just started pushing it back and trying to start it as I walked and after about a minute of walking, It fired up, I jumped on and road it back towards my house. It seemed okay again after it started, but then it started to hesitate again and then stalled again.
This is my first time ever doing stuff on a bike, so I am looking at it as a time to learn about the bike even though it is being sold. I really just want to get it back to how it was and just trying to figure out what my next step is. I am not really sure what it all means, but am hoping one of you has my next step to try based on the explanation I have provided.
Any help is greatly appreciated. I can pay someone to fix it, but am hoping to get it done on my own (with the help of this forum)
Thanks, the new bike has EFI, but still just trying to learn on this one.
