Stiill looking for help with my bars...put on 14 inch apes and have trouble with it spitting and spuddering since i have done this...trying like hell not to have to take it to the shop....

 

Watcha got?

Carb?

Fly by wire?

 

there is way too much info here ......not sure which issue could be the culprit.
Maybe check the rdiator cap for starters

 

If you did wire splicing and ran internal wiring its possible one of the wires got damaged during the wire pull....the soldering needs to be clean and shrink tubing on top of it for protection....oh and use a good amount of grease during the pull. Hate to say it but your gonna need to pull it all apart to see which one got damaged.....sorry to hear about that.

 

If the bike is TBW, then I would start with looking at your splices.

 

Drive the bike around beating the **** out of it. Pull into your driveway and rev it some more. If it still happens put in some fresh gas and some new spark plugs in her. Good luck!

 

Took the words outa my mouth.
