Help please! Sputtering and no acceleration at all.
Well, we had some rain here this past weekend. My bike now starts up fine, but won't accelerate! When I give it some gas, it starts sputtering. I had to ride it to work, then to my other work place, then home, at around 15mph 'cause it wouldn't go faster. I turned it on last night and I thought it was revving up fine. At first there was a lot of sputtering then it went away and only a little was still there... but this morning it was really bad.
So... I'm thinking either electrical or carbs... any ideas? I'm about to head out and tear stuff down, it would be nice if someone can point me in some direction. Thanks for any input!
Oh... when I give it gas there's sputtering and also a lot of backfires and some explosions at the carbs. I even had one of the vacuum plugs on the carbs shoot off from one of those explosions.
