Wobbling with trailer

I have a 2008 Ultra and I pull a I-podium utility trailer. All of a sudden I seem to have a wobble at any speed over 70 mph. New rear tire on bike and the trailer is also new. The first 600 miles everything seemed fine now all of a sudden it has started to wobble.I first thought it might be weight distrbution but it does it empty or loaded and any position on the road. All hitch components are tight,wheel bearings and air pressures are right on. Bike just went for a major check up and everything is great. Any suggestions. I have a rally to attend the first weekend of Sept. and would like to figure this out before then cause doing 60 mph for 300 miles will be unbearable.

A BUDDY OF MINE HAD A SMALL WOBBLE TO. I pulled his trailor with my bike and did the same thing but not so much. they replaced his axles to solve the problem. he has independent suspension. I notice that when I moved the handle bars is when it wobbled. at first I thought it was his hitch cause he has a reese hitch and it sticks out futher then mine. but it was something to do with one side or the other axle

Have you contacted the dealer with the problem? Will they let you try a different unit to check out whether it may be something with your new rear tire. Is your new rear tire the same size, type, and number of plies as the original? It sounds a little suspicious as a 2008 needing a new tire already. Maybe something is not proper with the rear suspension. Just shooting in the dark, but, I hope you find out the problem before you have to idle along on your trip.

Wobbling Trailer

Going to the dealer today. My bike has over 15000 miles on it already.I think I did pretty good getting that many miles out of one tire.

Check out this forum: http://forums.delphiforums.com/MCTrailertowing/start

Not giving you the blow-off Bubba, rather pointing you in the direction of a correct answer.

Not one person here can give you a correct solution, but only "guess" the answer without knowing your exact tongue length, measured ball preload/tongue weight, trailer axle width, trailer spring rate, trailer tire diameter and psi and rear tire psi for the bike.

"Guessing" isn't what you want/need when the result could be disaterous, if wrong.

Traveling at 70 miles per hour pulling a trailer with a motorcycle is crazy and dangerous if you as me. Just my 2 cents worth

If your trailer has small tires on it, there's a good chance that the trailer wheels are not maintaining contact with the road at high speed. You could also be getting some lift effect that causing the trailer to be lighter in weight or the combination of both.
