Hey folks, new guy here. I recently bought a 1979 R100T from a guy locally here in utah. Its in damn good shape, but hasn't seen any real riding in a couple years. The first think I did was check out the points set up and sure enough the ole bean can was full of crud. Put it through the ultrasonic at work semi disassembled and rebuild it with a touch of the required grease, new condenser and points. Replaced the leaking alternator seal on the crank as well as the bean can seal. Also put new plugs in, set of new 6v coils and some fresh wires. Voila, new ignition system. Freshened up the alternator with new brushes and a clean because it was covered in oil. Then I got to thinking about the carbs, and since I don't know the milage or how much its been ridden lately, I pulled off the float bowl and found a couple of the passages blocked up. I decided it was probably time to pull it all apart and here I am. They are a set of Bing CV 40s.
So I took everything back to the ultrasonic for a bath, and she's spick and span. But, Im wondering what kind of jets I should put back in it. I live in salt lake, so a majority of my time will be spent at elevation of 4-10K. The bike has the following in it currently
Needle Jet-2.64
Main Jet -160
Idle Jet - 45
What do people in the salt lake area or at elevation run with good luck?
Looking on the Bing/ BMW reference they are calling for a 162 Main jet for above 4K. The clymer is calling out a main jet of 170 stock, with 2.66 needle and 45 idle at what I'm assuming is sea level?
I figured that with the wear on the needle valve Im going to be in for a needle and needle jet, idle adjust screw is a wee bit rusty, and a gasket kit. Figured I may as well order jets while I'm at it. EME is going to love me.
Thanks for your help in advance, I have always been astonished at the wealth of knowledge this website has.
