I know this may be a silly question, but when inspecting a used bike, is there any way to tell if it's been jetted or not, without tearing it apart?

Thanks.

 

Not a silly question. If you don't know, then you don't know, there's nothing wrong with that. As for being able to tell, I don't see how visually you could tell. The jets are inside the carburetors. Without disassembling them, you wouldn't know for sure.

 

Thanks, that what I suspected. I just thought there might be some performace charastic that might give you a clue. The bike I'm looking at has aftermarket exhaust so I was concerned that it was carburated properly. I guess the only way to know without dissasembling the carbs is to put an EGA on it to make sure there are no A/F issues.

Thanks.

 

If the owner will let you lift up the tank, you can remove the diaphram off a carb and see if an aftermarket needle if installed

 

Hope you fine the answer you are looking for mate!! But the best thing to do is make sure if you can!!
