That amount of head shake doesn't sound right, even with the bar mounted shield. Perhaps the front tire is out of balance or the fork settings aren't matched up?
Yeah I have the front and rear drag specialties coming in this week, hopefully. I have been researching a solid propylene one like they used in the Vance and Hines series, but it looks like I have to deal with sourcing one and I don't know exactly how hard on the chassis/frame/linkages all the vibration. I personally don't care about vibration as long as the bike doesn't rattle to pieces.That looks like an XR750 kit. It would take a lot of modding to make it work on the XR1200.
If your front motor mounts are shot, then the rear certainly must be - and your engine stability and rear wheel control comes mostly from the rear mounts.
Fairing is definitely one of the last mods but it's nice to find a blueprint and source parts. The next "major" mod might be a Power Commander for an XR1200 that is for sale near me, $300.There is so much fun to be had with the XR before that point. I would definitely start inside and work my way out to the fairing. That Shaw’s bike is a builder’s showcase that shows what can be done, not what needs to be done. Haha
Slowmo, I had the same problem with wobble when I first got my XR. It was perfectly fine until about 50mph and then it would just wobble for no reason. Long story short it turned out to be the rear shocks. Not only were they not set for my weight they were also jacked up really high with the the sato rear ride height adjuster installed. It all came down to the load that was being placed on the front wheel. I had the suspension checked and removed the ride height adjusters and it went away. Now the XR is as solid as can be.
