popping at cruising speed

[allenmp]

Ok its driving me nuts if I hard accelerate it has shitloads of power and sounds good
I just got done rewiring the bike
put in an ultima programmable ignition
and a new s&s super g carb
I static timed and starts great lots of low end power and top end power but holding at about any speed its popping and hesitating
I ran it up in rpm for about 3 miles turned off key and pulled plug white indicates lean I am at sea level running 33 & 78 jets with v&h big radius and a dual runner intake a shop talked me into a 80 main
seems big but they are the pros rode it with the 80 seems to have helped but still there
checked
Timing, sprayed starter fluid around gaskets, tightened exhaust flange bolts (were loose)
How do yall get to the bottom rear bolt on a 03 chop couldnt get my socket to it
I am now at 33int and 80main on jets and still white on the plugs and popping any ideas something I may have missed any help would be great
thanks mike

I'm not a great motor guy but a 33 inter sounds way small.

Sounds like your not getting enough vacuum through your air bleed to transition from intermediate to main jet. It will stumble and pop. Change your air bleed jet start at .048" and work your way up. I'm running .050"

33 - 78 sounds right to me.... (I am running 32- 78) could it be you have some air restrictions? what air cleaner are you using? EDIT: I just saw you are using the Dual Runner.

This thread will give you an idea http://www.bigdogbiker.com/forums/fuel-air/14439-what-jets-do-you-run.html

yeah many shops get confused when you throw the "Air Bleed" name at them ... just ask for a .048" main jet it will screw right in..... your going to have to remove the bowl

 

[allenmp]

Ok called the parts dude we will see ill keep ya updated
ill look for a how to on this and get it changer
I second franco your a good fella
thanks
Mike

Thanks Mike & Bill

Mike, you don´t need a How To, just drop the bowl, and with a flat screwdriver, as the same you used for the Main Jet, unscrew the air bleed jet and screw the new one in. that´s all.

S&S has a tool also for Main Jets, it is very handy to have if you are going to experiment with Jets. :up:
