Bogging real Bad

[bansheeman_05]

I just got done putting on my new Keihin 28MM PWK's. I also put a new twist throttle setup on the bike. To my suprise, the bike fired up on the first kick and idled nicely. I have the air screws out two turns. The bike is boggin really bad and will not open up at all. I was just wondering if the first thing I should do is let me air screws out another turn or so? It does not seem to have any air leaks or anything. Let me know what you think. Thanks!

What size mains & pilots? Whats done to the motor ? What elevation? What gas and what premix& ratio?

Are the carbs in sync???

[bansheeman_05]

The mains are 155s and the pilots are 52s. I got some input on what I should start with from some guys on here. The motor is pretty much stock, except for Bills Pipes and Silencers. I live in Central PA at about 1600 ft. I use Yamalube 24:1.

The carbs are synched, I took the air filter out and checked them.

 

I have an update. It is midnight here and I am still pissing with this stinking thing. Anyways, I monkeyed with the air screw and now have it at 1 turn out. The bike still idles nicely, and it seems to have a good takeoff. As soon as I hit midrange though it bogs again. Could this be needle position?/ Somebody please help me out. Thanks

Try the needle in the middle clip, because the needle adjusts like 1/4 throttle through 3/4, and main jet is like from 1/2 to full throttle.................

I would also try leaning out the fuel mixture. You're using alot of Premix Oil!

I will try that. I just was running that because that is what the owners manual says to run. I have noticed that everyone on here seems to run 32:1 or so?

i personally use 50:1 (amsoil dominator)
