thru the winter I'm going to research which type of rear shock to get,I've got a 12 ultra with the ss 124 lc,I'm an aggressive rider who likes the floorboards scraped at least every hour :grin::grin:
whats the recommended rear shock and why?
i have a high speed wobble around 140 kmh and the local hd dealer is telling me its from the rear shocks and swing arm,i have played with the tightness of the neck bearings and it hasn't changed anything.
looking for some feedback ,thanks !

What are your wheel and tire sizes? Just curious as most of the high speed wobble issues I've seen have been traced to the wheels and tires. Namely 21" front with 18" rear, 200mm tires and such.

i am running a 21 front and whatever stock diameter is i don't recall,but its a 180mm width

i never had this wobble until 4000-5000 kms after new motor install,not sure if that coincidence or not

and its only during cornering for you guys in mph its about 90 mph

Sounds like the drive train is out of alignment. You are saying wobble, is it wobble or is the back end wollowing out?

This, or the swing arm bushings are shot. Your shocks won't make you wobble unless they're adjusted differently or one's leaked out its oil.

handlebars start to jerk no idea if its front or rear doing the wobble. stock shocks and i have played with the air in them and it doesn't make any difference either.

Not wollow then, wollow is where it feels like the rear is coming out from under you in a high speed sweeper. I would check the alignment then. Glide Pro has some good DIY videos if you want to try it yourself. I would loosen up the motor mounts first, and let the motor run for awhile and see if it will settle back in alignment.

An alignment issue would be evident by riding hands off and seeing where the bike tracks. My money's on the swingers bushings.

It would only be evident if the front and rear tires happen to be tracking in parallel planes causing the rear to kick out to the side. I don't think it is the swing arm bushings because the bike handled fine then the motor was swapped now the wobble, but I would probably end up checking it all before it was all over.

They're wear items, and it's a 4 year old bike with a motor that's going to stress them. They're also a well-known source of "Bagger Wobble". Just sayin' they're worth checking.

since you had a new motor installed I would definitely check the motor mounts top and bottom.

Go have a look at this site it has quite a few good videos on alignment set etc...
