Hello everyone!! This is my first post on this site having just picked up a 1980 550E and I am stoked to have a found such a resourceful and helpful group!!
So the issue I am having is I am getting conflicting messages from the internet!!! (I know right!!)
I am a marine mechanic and know my way around carbs well enough i would say and when I bought the bike the needle was stuck and the fuel was *@%^$*@%^$*@%^$*@%^$ing out when i could get it to run long enough.
Long story short.. those carbs are a royal pain in the arse to get out with the airbox in the way but i did it and throughly checked every component long enough for my wife to wonder what the f#ck I was doing in the shop for so long!
Now leads on to my question! I can get it run pretty nice and peppy at low rpm but when I try and punch it past 4/4500rpm it dies. I figure its leaning out and makes me wonder if the air mixture screws on top are set incorrectly. Some folks say its 2 turns out, on the sticky on this page it says 3 1/2 turns out. Which is it? I have the CV slide carbs..
Cod this be the issue? Also makes me think it could be the timing isnt advancing..
Anyone come across this? This bike is 4 days old for me so I'm keen to get all the bugs out before I insure it. It does already have upgraded ignition, new plugs, fresh gas and the carbs were cleaned properly with my ultrasonic cleaner, the petcock is pretty retarded but it is stock still. Probably going to be changing that!
