1994 Honda shadow 1100 carb issues


  • So my bike has cobra drag pipes on it. I bought the performance carb kit in it. I put 198/48 in front and 200/50 in rear. I adjusted the idle air screw out 2 turns and it randomly pops when I'm not on the throttle. Wide open it runs good. Idk if I should put the smaller jets from carb kit in. I really could use some advice it doesn't seem to be running rich or lean. Also do I need my air vet control valve hooked up. It's a plastic valve on right side. 



  • Could not having velocity stacks be the issue? I was on a budget but want the bike to run right. 


  • @Ryan Whitaker the performance jets are meant to be run with an open intake. you can just remove your air filter and that will reduce the resistance and allow more air in to match the bigger jets. im not sure what air valve youre talking about. if you can post pics that would be helpful. 



  • I believe it is for evap the hose goes to roun canister in front. 


  • Thank you I ordered velocity stacks 


  • Here the picture 


  • @Ryan Whitaker youre going to get rid of all the epa crap.  you dont need that stuff =) 


  • Will it affect it if it is hooked up? 


  • @Ryan Whitaker yes the PAIR system is meant for a fully stock setup
