Dropped my bike, now she wont start or idle properly.

I dropped my bike a little while ago and I made one or two posts about it to try and get some answers, but I never got enough info to actually fix my issue. So I made a video detailing and showing the issues with my bike because I am very bad a writing the details of what is going on.

The issue is that I dropped the bike on the right side, and now it doesn't run correctly. The carbs, choke, petcock, and throttle assembly are all clean and function perfectly. All of my carb boots, vacuum lines, and gaskets are in good shape. I think that the problem might be valve related or timing related. But I'm really bad at writing things down, so I'll post the link to the youtube video.

So, I cant post links apparently, so put a period between the "u" and "b" in youtube and that is the link to the video.

The Video is a giant waste of time ,mine & yours. sounds like a stuck throttle did you try to turn the throttle down?

The throttle isn't stuck because the bike will still rev higher if I give it gas. Any attempt to turn the idle down just makes the bike die, fuel screws are at 2 turns. I've tested for vacuum leaks and I haven't found any. I did notice that when I disconnected the bike from the car battery as the bike was running, it started to, and eventually did, die. So my right side cylinder is misfiring and the engine isn't keeping the battery charged sufficiently.

have you encountered anything like this before?

16adenni-

you need to get a voltmeter on the battery and charging system components. Load test and ascertain battery condition first and foremost. Your local auto parts store may be able to do that for you.

As for the high RPM (after drop)...have you removed the tank, visually checked ALL vacuum hoses and throttle cables?

Examine the petcock, too...possibly the diaphragm is leaking vacuum?

It is also conceivable, your drop dislodged something in the float system...a float pin or clip? ...a carb pull and exam may be necessary there.

Just submitting some ideas and possibilities to check. Process of elimination.

I'm going to have to file a formal protest on that statement. The float bowl has two thingy mcdingies, that the float pin/float pivot fits into when the bowl is installed. The pin measures about 25mm. The inside distance between the thingy mcdingies is about 25.6mm. This leaves a distance of less than 1mm, that the pin can move from side to side. Not near enough distance for the pin to dislodge from even one side.

I've had a float needle break during use from age and condition. I would image something internal could break from force from an impact.

^ I wasn't talking about the float needle. Just the possibility of the float pivot pin dislodging.

Seriously? You're trying to school ducatiman on carburetors? I'm sure he's well aware of the "thingy mcdingies".

^ I wasn't trying to school ducatimam on carbs (I know better than that), I don't think he was even ever referring to the float pivot pin. Was looking for conformation on that, or if it was possible that I was wrong. I think he did that. I stand by my earlier statement.

Point was...i was suggesting OP needs to pull his carbs and examine the float system in each to eliminate whether drop damage has occurred within....not presenting evidence to the Supreme Court.

I posted a variety of possibilities earlier in the thread...and OP hasn't chose to respond in 3 days. Why, pray tell?

you should PM the OP if you are concerned.
