Hmm...I just placed the knob of the enrichment screw to the left of the floater cover knob so I might adjust the enrichment screw clockwise, against the initial 2 1/2 turns. The screw now sits at about 2 turns. The RPM's are not going down. The idle screw is all the way out. Now what? The panels just came in. I'm to put them on while I evaluate the situation....

Allllrighty then! I adjusted the valves this morning and she turned right over. It's a good morning. Now...she DOES idle a bit higher than I'm comfortable with, but I'm thinking it maybe the jets in the new carb. I started with the 2 1/2 turns on the enrichment screw and placed the float cover back on. So...the more I turn it clock-wise during the adjustment (allowing more air) the higher the idle. I have it turned as far as it'll go counter clock wise, as far as the stops on the bottom of the carb will let me go (with the initial 2 1/2 turns) and the idle is still high. My throttle screw is BARELY touching the arm. Anyway, I haven't test drove her yet. I'm going to in about an hour. I'm waiting to Fedex to bring me her lower panel replacements this morning. It's going to be a good day..

When you turn key on, do you have any power at all? or does it crank but no start? Give us more info Yes she cranks very well..just won't turn over. I did all that I listed in the above message. I'm thinking though, while the engine was running I adjusted the valve settings (on the outside of the cylinder head). I shut the bike down. about 20 minute later I tried to start her again. All I got was crank. Maybe I should put the settings back on the cylinder head. I'll check it tomorrow. And I'll check the Intake manifold for cracks too. Alleyoop...why does your carbuerator diagram show the coolant lines -Not Connected- ?

I appreciate your assistance Richardson. When I started the bike this morning, she purrrreeedd. It was after a ruff start, but she seemed to even right out. as far as the idle is concerned, the screw is back out...alot. Almost not even touching the throttle arm, and she still idled at about 2400. I adjusted the valves slightly and brought the idle down though. She sounded good...while she was running. Then...I shut her down for a while. When I went to start her back up I got nothing. I can see the gas misting out the bell housing, I checked the current at the cdi and the battery is giving me 13.4 v. Still...she won't start. I want to know how to test the coil or something. I feel like I'm not getting a spark at the plug or something.

I have a 2008 YY250 T. First it started the "backfiring"thing and bogging down. Eventually it got to the point where it would bog down right after warming..and completely un-ride-able. I broke down and bought another carbuerator. I sounded just fine...untill it warmed up. Then it bogged down too. Now the bike just doesn't want to seem to start at all unless I remove the air box and cover the front of the carb. with my hand. I really need this bike running. Help.....
