Hello all. I am a noob here and was wondering if I can get some advice/suggestions on a used TW I just purchased. I got it a few weeks ago from a private seller. It is a 2003 TW200 with about 2300 miles on it. When I test drove it, it was fine but it seemed a little sluggish so I talked to the owner and he agreed to have the carb cleaned before I bought it since he had left the gas on all winter and I figured it was gummed up. It was cleaned,the oil changed, a new plug, and cleaned air filter and I picked it up and brought it home. When I first got it home, it didn't want to go when I gave it throttle. It really only ran normally when the choke was on and as soon as I took it off and gave it gas, it stalled. If I babied the throttle and it warmed up, it would eventually go fine. I rode it around, maybe 30 miles worth, over the past two weekends and went out yesterday to give it a go and it was acting real different. I was still having the baby the throttle but when it finally got going, it had no power at all. It would only roll on flat ground and the slightest incline was too much for it. I didn't ride it and parked it. I took off the plug to have a look and it looks like it is running lean, but I am not sure. There were a few white/yellow spots on the plug. I also did the lazy man's carb clean but the thing was clean. The engine will rev up, just no power. I am hoping it is just a carb problem and maybe I have wasted a post, but I wanted to see if anyone else has any ideas as to what my problem could be or anything I should check. I was really looking forward to finally owning an dual sport but now find myself just looking at it. Thanks for any help.
