Hi
I knew I had a problem with my rear cylinder because the spark plug was wet and the temperature of the back head was a lot cooler than the front head.
So last spring I ordered a lambda sensor for both cylinders, I welded the sensors on an old header.( B sensor is back )
Now I have all kind of main jet, air jet and needles, I am ready to do some jetting.
But OMG
the rear cylinder is not running (no reading ), first I reverse the lambda sensors and spark plug to test sensors and plugs (OK)The spark is good, the compression is good 160 psig on both cylinders and I have gas going in but something is weard, when I crank the carburator arm of the rear cylinder I can feel a lot of air and gas coming back from the cylinder ??
On the road when there is load on the motor I can feel the torque and the lambda give me some reading, on first gear if I give a quick shot the front wheel goes up and both sensors are about the same but with no torque the rear sensor is always flat, no reading.
