87 fltc, crank case is not ventlating, this causes it to suck the primary oil into the crank case an fill up the oil resavoir tank. I have installed a new oil seal on the front sprocket shaft, I have also checked the timeing of the crank case breather, also I have checked the two oil breather hoses by blowing air through them. no change. after riding it 100 mi, the primary oil is down to almost no oil. its all in the oil tank . HELP !!!
