I have a Banshee that I aquired, put new top end in and have been through the carbs 4 times. Bike will not start without a spray of either, then i can keep it running, but it wont idle no matter how hard i try to adjust it. partial throttle keeps it running. The left cylinder runs all the time, the right cylinder only seems to pick up and run at higher RPM. Spark is good on both cylinders as is compression.
A twisted crank could explain why the right cylinder isnt seeming to fire, and also very hard to start. My jetting is all stock. Actually the entire bike is stock besides decking the head .020". Compression is around 150psi in the right cylinder, and 145 in the left.
Im going to try to see if one cylinder is at TDC, if the other is at BDC, but I wanted to ask would a twisted crank cause these issues?
