I am a long time Yamaha rider. I just sold my 94 and 95 Yamaha Vmax 600 machines. I cleaned the carbs every year without an issue. Most years a basic cleaning but other years I would tear it right down.
This year I picked up 2 600 tripple machines. 2002 vmax and a 2000 sxr. I cleaned the carbs. The sled ran well before and I only cleaned the carbs as a precaution. I tore them right down and used a combination of compressed air and carb cleaner to clean them. I have never had a triple but everything seemed fine. I put it back together last night and she will not run. It seems like the idle circuit might be plugged. I started the sled. It ran for about 10 seconds the rpm went up to about 3000 and then it died. I started it again and without the choke on it revs high: about 3000. I figure it must be running lean. When I turn on the choke it runs like a 3 cylinder for a few moment s but return to running like crap. When I hit the gas I cannot get it to spool up.
I hate the thoughts of taking it all apart again but sound like it is inevitable.
Will only one plugged idle circuit in one carb exhibit this type of symptom?
Any advice on what I should try first?
One other note of interest; when I removed the air screws they were all adjusted to 2 full turns apart from one. It was turned out just one turn. I set it the same as the other ones; 2 turns. What failures would I notice if the air screw was set wrong?
