15 Road Glide High Speed Wobble
Friend has a 15 RG with a slight wobble at 70+... he just did a lot of work to the bike so narrowing down to what the issue could be is not so easy. Added a 21" front and 17" rear wheels, Metzeler rubber on both wheels, he also added the lower fairings, extended bags and new rear fender...
Took it to HD in PCB and they adjusted the neck... still wobbles.
Local dealer has suggested lowering the front end and even raking the trees! I think both are unnecessary, especially raking the trees. PM told him the Metzelers like a lot of air and to run 50 in the rear and 45 in the front... he's trying that this afternoon. Someone even said the 21 and 17 wheel raised the bike and is screwing up the aerodynamics underneath the bike... seriously...
He's tried adjusting all the vents while riding and it doesn't help. Odd part, if he takes his feet off the floorboards and stretches his legs out the wobble gets a lot worse!
Does it sound like an aero issue? Could it be the bags and the fender/lower fairing? Anyone with a 15 RG running 21/17 combo have this issue?
