wow what a difference no more shaking of front end I put super brace,all balls and progressive mono tubes on my bike like a new one goes down the road like a dream all of the slow speed wobble gone it is a lot more fun to ride now. but beware I catch my self riding just a little harder haha.i am not sure if anyone part fixed problem but all I know it worked. also had new progressive 1100 spring install along with new hose seems to ride alittle better also new bridgestone rear tire I wasn't so impressed with work done on rear but I have been told it will get better still seems to ride rough in rear will find out headed to las vegas 18 days of freedom haha
Good morning Winghead, I rode my trike build (86 GL1200A/84 Jag IRS) yesterday for the first time looking for problems to fix before I start the sheet metal work. I have the low speed wobble. I took it out on the highway after the traffic died down and the wobble diminished as the speed went up.
I didn't notice any problem when I checked the bike out before tear down in March, 2013. I did some quick measurements this morning and found I'm a little out of spec on ground clearance causing some what of a rake effect on the front end. I'm going to check this out when I get a chance to work on the trike again.
In any case thanks for posting, as this offers another thing to try. I will do some research into what is available for the 86 GL. By "all balls" I assume your talking head bearings? That's another thing I'm going to check, won't be able to get to it for about a week. Thanks again, Be Safe, Perry
When you trike a bike, it changes the dynamics. I have had 2 trikes (both Lehman). The 2000 did not have the triple tree raked and it had low speed head shake (wobble). The '08 has the triple tree done and no shake what so ever. They use about a 4 degree rake.
Thanks Fordofcanada, Yes it does, that's why I did the ride. I expected some things but was a little surprised on the wobble. It's not all that bad but I would rather it not exist. The trike steers like it has a rake kit, that is with little effort. That is kind of nice, but that's also why I thought I might be a little low in the rear.
During the build I discovered I was out of spec (high) with the IRS so I adjusted it in the fixture. I could have lost some ground there. I can get back into it in a week or so.
I just ordered fork seals, Progressive springs (couldn't find Mono Tubes for the 86), and Head bearings. I had planned to do this anyway as it is a high mileage bike, just hadn't got to yet. I'm not going to get to excited about the wobble until I do the fork rebuild and install the Progressive air shocks on the IRS.
I have to admit I was more concerned before I read wingheads post. I wasn't sure what all I could do to find a solution. I was also thinking I would have to figure a way to check wheel alignment, although I fixture it true and square to centerline of the GL., may still have to. It's fun to ride even with the wobble, can't wait to ride it after I work that problem out.
I always appreciate input from the experienced, it's the best way to learn.
Thanks again and have a great day, Perry
