Restoration of 1986 K100RT Img_0810As alluded to in my introduction I decided to take on a little project putting together a 1986 K100RT old police bike, came as frame and boxes of parts. After a year of cleaning, stripping, replacing and painting finally in a position to try the engine. And after 20yrs since last run started first time.
So far so good runs really smooth on idle slightly fast but as soon as you tweak the throttle splutters and dies. Smells really rich as well. It has new injectors and good spark have read lots of ideas with regard to similar problems from the TPS, temp sensor the AMM. was wondering if there is a logical way to eliminate issues and whether it just needs adjusting. Any advice gratefully received.

Check all the rubber bits for cracks that can allow air leakage, it's a common problem on these old machines, and is probably what is causing the lean condition and death when opening the throttle. Most notable is the zigzag hose from the air box to the crankcase which is located between the air box and the relay box.

Thats awesome it started first time!
There is a bypass screw on top of the MAF that you could try adjusting, i believe this will change the fuel/air mixture. On top of the MAF/filtef box there is a small plug that you can pull off to get to it.

Great news after rebuilding the brakes and adjusting the the throttle sensor bike now runs, goes and stops. Only small issues the gear selector indicator was generating random gears. Least of my problems, now that I know I have a strong engine the fun can begin. Fabrication time!!
