Hello Everyone. Last summer I bought a GS 450L. This is my first motorcycle, and so far I have been able to get it running. I do have a few questions however. My first question on the bike is pretty simple. Does anyone know the model number on the carbs? I know they are Mikuni Carbs, but I don't know the model number. My second question is about the choke lever: is up choke or is down choke? My last question is a bit more complicated. I am able to start the bike and it will idle around 1.5k-2k rpm which is alright, but once i give it even a little throttle It revs up to 3.5k-4k rpm, which is too high. it does not idle down, and I have to shut off the bike in order to get it back down. This happens while the choke lever is down (the bike backfires and dies if the choke lever is up). I am really excited to get this bike ready, and it really helps when people share their knowledge. Thank you!
