Wow these carbs are a fun chalange. I have rebuilt and rejetted my carbs, and chased down many problems. The new one is the bike will take off on it own, I let it get up to about 6000 rpm before I hit the kill switch. Basicly, it feels like the choke is on. I have cleaned the entire carb, and checked for vacuum leaks at the manifold and the vacuum take off ports. Any other ideas. Thanks for the help.
I had similar symptoms when I tore down my carbs. It was driving me nuts. I pulled everything, double checked all the movable parts and o-rings and gaskets. I confirmed that the choke was working and not binding.
Put it back together and it has run fine ever since! I probably fixed something I screwed up before but I have no idea what :dunno:
I tell my wife, sometimes you have to take things apart because demons are trapped in there.
good luck
Sounds like it's set lean. Check the air/fuel mixture screws, should be backed out about 3 turns. Also check the float heights, if they are set too low, they will also restrict fuel flow and cause a lean condition.
Thanks for the tips, hopefully I have a lean demon to get rid of. It was doing something similar due to being rich before, maybe I went too far when I tried to lean it out.
Don't forget to check that your throttle cable is routed correctly.
