Sputter, Vrmmmmmm, POW

[Dragonslayer]

The scoot picked up some bad habits over the weekend and I don't know why.

 

All of a sudden, the idle is real low, on acceration, in all gears, it started sputterring then eventually smooths out. On deacceration it backfires, if suddenly it sounds like a M-80, if not so suddenly not quite as loud.

 

I pulled the plugs which are all realitively new, like a month old. They all have about the same light covering of black dry soot.

 

Over the weekend I was riding two up pulling a trailor.

 

Got any hints?

Hi Bob,I'd say the choke is not fully disengaged....

My first guess: connections to the TCI.

Good Guess because apparently you were right. I checked the connections and they appeared to be tight and fully seated. But, I pulled them loose anyway and sprayed them with CRC contact cleaner and plugged them back in and the problem totally went away. WOW

Thanks for the advice
