I know this has been discussed a million times before....I think I even have a thread on it, but I need help diagnosing my bikes condition. If you are feeling in a good mood and want to help me out then thank you VERY much. I have read every carb thread on here and I am still slightly confused. I have vm30's on my 82' xs400. Right now I am running 150 mains and 40 pilots. i'm on the middle needle clip.
Here are my symptoms.
It runs good all the way up to about 3/4 throttle then if you give it WOT it cuts out and slows down. If I don't let off the throttle it will keep losing speed/rpms until I let off. As soon as I start to let off I get a burst of power. From what I have read this means it is to rich on top.....right? Here are what my plugs look like. Thanks for any and all help. Let me know if you need more info. Thanks.
