Did a 103 kit cams heads pistons SE flat top. Before I did the build I would start the bike and off I would go. Now if I don't warm up the bike it runs like crap is sputters and coughs doesn't die. Is this the tune should I try retuneing. Thanks any help would be appreciated

 

sounds like a little tuning mite help

 

I would get your bike retuned, my guess is the Fuel air ratio is off, especially at idle. My bike when it is cool out ( now ) will pop just after its coming off a high idle. It's probably to do with the cooler air we have now vs summer time being pulled into the fuel air mixture and making it a touch lean.
