Hi guys,
Sorry for my bad english. Not every day I write in mechanical terms.
I bought a NX650 from 1993 that worked fine. Removed the engine to paint the fram and change a few parts like the handlebar, lights etc. Also shortned a lot of electical cables since they where way to long. Started the bike and everything was fine but when I was to drive it, it drove very jerky in low speeds and even gas. When I stopped the engine could rev by it self slowly up to around 6-7rpm. The only thing that I´ve messed with is the choke since the new handlebar is higher so I loosened that a bit. (Did not help to put i back where it was). When I turn it off it also makes a sound from the exhaust. Not a bang but more like a slow loud "Blaaap". Sound like a wet fart.
I checked for leaks around the carb and engine but it does not look like it draws air from anywhere. I tried messing with the screw under the carb but that did nothing at all. Got it to work fine for a while where it did not rev by it self at all but it was still pretty jerky. Drove for a few miles with that and tried to fix it byt tuning the carb but now it revs by it self again..
What could be the issue? Could it be some electrical problem or is it the carb?
Regards
Marcus
