I had been messing around with the jetting, trying to get it just right.
I have installed the pipes and K@N with a jet kit. The bike was running great while on the gas but at I ran around town and the rpm go around 3,000 the carb would backfire. I tried everything, tps adjust, carb sync and It seemed to be a lean condition in the rear cylinder.
You can test if you’re lean by getting to the rpm inquestion and pulling the choke out partway. When I did this the bike ran much better. Moving the clip down one position on the rear cylinder and opening the mixture screw about 1/8 the bike now doesn’t miss a beat. Idle is great and no "burp"
I also made some block offs for the SASystem to get rid of the exhaust popping on deceleration. No sure, but I kinda liked it.
But I can now take all that crap out.

How did you 'pin point' it to the rear cylinder?

That's a handy troubleshooting skill, how did you do it?

Tape off part of the rear stack?

Sounds like you were able to 'nail it'.

Thanks Jeffers

two things.

first the backfire seemed to me more from the rear cylinder than the front.

second I rode the bike on a long (450 mile )ride on saturday when I got back I checked the plugs. the front cylinder looked nice and chocolate color, the rear was burning leaner than the front.. more white.

after adjusting the carb the diff was amazing. I havent checked the plug burn yet but i will let you know
