I have a 1994 R 1100 RS with about 52,000 miles on it. I have only owned for about a year. During that time I have replaced the right throttle body ( a mistake since I could have just rebuilt) and I just finished rebuilding the left throttle body along with other maintenance (oil change, air filter change, valve adjustment). I have attempted the Zero=Zero procedure along with synching the TBs but have had little success. I must be doing something wrong. My idle is too high and the throttle is still surging. I have noticed there is quite a bit of slack in the cross over cable on the left TB. I am wondering if the cable is too stretched for me to achieve a decent TB sync. I've tried watching youtube to figure things out but still find myself confused. I appreciate any insights you might have for me.
