A head shake is actually quite easy to diagnose and repair. First off, I feel bad for you about all the expense. I think you'll find out what REAL expense is if you do the 650 deal. Now, the head shake; do you have a windshield ? At 75, passing a large truck, that would be a major cause. Bad head bearings show up mostly at lower speeds (50~55) . Still, check for bad head bearings, tire pressures, AND, chain tension. A chain with a tight spot will cause a head shake. # a word about windshields; ever see a stop sign shaking in a high wind ? It loads and then pivots on it's axis and unloads one side, repeat , repeat, repeat. The windshield loads and then pivots the fork and unloads one side. The larger the shield, it gets worse. ## on a complaint about head shake, AHM directs that all accessories be removed before diagnosis. (see above) [ yes, we will strip a Wing to only original components] # improperly maintained chains that have a tight spot really shake a front end ? Oh yeah. A chain drive is constantly pulling the back wheel to the left side and that twists the wheel to point right. Every time a tight spot yanks on the rear wheel, the tail wags the dog. "Wait for an older year" ?? NO, just an '83~'85 650. Later 750's maybe. I have two 700's

To: "Nighthawk Motorcycle Lovers!" <[email protected]> Date: Friday, July 3, 2009, 10:33 AM Thankx Dennis for replying back:-) It would be a step up for me. I will be able to find more parts for it if need be. The only reason I am selling/trading it is because the other day when I got up to 75 to go around a semi, the front end started shaking REALLY bad and I can't find out why other than a fork problem and from what a Honda tech told me would be expensive. He has worked on my 450 since I bought it last year non-running and have spent $2100 on just work. I have done some of the work, but needed help so... I am meeting the guy with the 650 Sun cause he is taking it to a bike shop to have it looked over and get the tank creamed before he lets me see it. I will definitely hear for the valve noise. So maybe wait huh for a older year?? On Jul 2, 9:00 pm, Dennis Hammerl <[email protected]> wrote: > IMHO; I had a '82 CB650sc.
