Answer for Gunnabuild1

G'day, no its not an ex police bike, the fairing i purchased for it some 18 years ago when we were living in Sydney is called a Sebring. The bike originaly had a handle bar mounted bikini fairing but anything over 110kph got the death wobbles happening & my testicles are a lot smaller than my brain so had to back off throttle.
We tried every trick in the book to fix it, swingarm, headstem bearings, shocks, for oil weights you name it we tried it except to take it for a lap without the bikini fairing. Once we did that the wobbles were a thing in the past. The Sebring fairing was a little disorientating for the first few rides, but soon enough i was enjoying blasts up & down the Old Pacific Highway, (Cowan to Gosford) until the New South Wales Police Farce got too hot, & my points & wallet got too thin.

Same story with the useless fairing Yamaha outfitted the 1983 Seca 900 with.
Poorly designed.
Aerodynamically unstable.

Once the air coming across the front of that fairing reaches 117 mph, the fairing begins to oscillate to the left and right.
The oncoming air compressing the unsupported fairing creating the form of an aircraft wing ... with a high and low pressure variant changing sides causing the bike to start to follow the movement as the fairing begins looking for a balance through the wind stream.

Not a good situation.

 

Thanks for that answer Rick, have you had a look at some of my previous posts about my restoration project of the old girl, its an aweful thing to admit but i have no one to blame for its poor condition now when it used to take out many many awards at rallys across Australia, oh well the plan is a 12 month one to get her back on the road & its quite the feeling after spending hours upon hours in the shed pulling her apart, polishing alloy, stainless etc to see just how well she is comming back. God bless her sweet pistons & the thrill we used to get & will again one day. Can anyone tell me is it wrong to talk to the bike & show it pictures of what it used to look like etc.
Regards Bones.

 

Thanks for the reply.
Get a lot of satisfaction out of fixing up your old friend I bet.

 

Nope, can't tell you that. I mutter at my machine constantly.
