86 sei rear wheel

Postby B-2 » Tue Jun 28, 2016 5:41 pm



I have a 86 sei when I take off from a start it feels like I have a low tire, its not making any noise it just feels like like the tire is really low on pressure but when I get up to speed its fine. I put a new tire & new shocks on it awhile ago I checked it & I can't find any thing loose. When I have the wife on it feels fine its only when I'm by myself that it feels loose ( :lol: & no I didn't tell her that I still want her to ride with me) I guess it could just be the new tire but we have been riding it for a few months now since I put the new stuff on it. It doesn't feel like it's getting any worse & its only when I ride it by myself. Any Ideas

Personally If you havent had the differential off to check the splines and ujoint and anything else back there I would. It shouldn't feel any different. I would dig a little deeper, your life may depend on it.

I took it all apart not to long ago when I put the new stuff on & everything looked ok but your right. I guess I'll take it back down again maybe I missed something. I'll let you know what I see this time. Thanks Bill

I would think the problem would show it's head most when loaded the greatest?

At very least ..... place the bike on center stand and lay down and grab rear tire at front and rear and try twisting it right left right left ..... possible the rear wheel alloy is work expanded and loosing it's grip on the wheel bearing over on the drive side, that bearing is nearest center line and takes the majority of loading on rear and 1200 wheels have little casting around it.

Best bet is take apart and inspect.

Other .... remote .... possibility is loose swing arm bearings at front.

If you find a problem with the wheel, you can try taking it to a machine shop .... but I don't know that a fix is long term. 1200 wheels that aren't in bad condition and not in use are rare now. Far fewer 1200s were converted to trikes early in life. The good news .... thousands of 1500s were converted and the final drive, wheel, axle, rear brake rotor, caliper bracket, spacers, drive adapter, and a 150/80-16 rear tire will work. The 1500 has same ratio, the brake rotor is a little larger and gives a better brake, and the wheel uses a double row double width wheel bearing with more wheel casting supporting it as a drive side weight carrying bearing. 1500s do not have the problem and whole take off sets are not hard to find around trike shops and their owners.

Look over this ..... viewtopic.php?f=5&t=33887

But still .... I would think the problem would show it's head most when loaded the greatest?

I have the SEi also. 44,000 miles. Rear wheel hub is wobbled out causing play between the drive side bearing and it's steel seat/bore. See my thread below your thread. I feel the 1500 upgrade is the way to go if you have the same problem as me. To get a good look at this you must remove the rear wheel and pull the drive spline. (comes off easy) and check the bearing that is pressed into the wheel. There may be play in the bearing, ( best scenario), play between outer race and steel sleeve, play between steel sleeve and aluminum wheel casting. I am going to a machine shop today to get mine looked at. Good luck with your SEi. Aren't they beautiful! :roll:

Thanks for the info guys but I think I found out what the problem was. I changed tire & shocks at the same time I went to heavy duty coil over shocks & put them at the top setting. Well I moved it down to the middle setting & it rides like a dream now with the wife or by myself. I also think that the tires not being the same brand had a lot to do with it the front is a dunlop & the back is a Shinko. The dunlop is not as soft as the Shinko so it holds the road different but changing the shock setting made it feel so much better. Taking off now it does not feel like it has a flat tire any more ;) funny how just a little change can make such a big difference on a Bike. Thanks again for the info everyone
Good luck with yours Rusty Bike & yes I really like the looks of the 1200 This is my first sei but I have had other 1200's we just like the look of them

Thanks B-2. the machinist said no problem on the repair. Waiting for OEM parts now. Glad you have yours worked out. Would you say that the SEi is significantly more powerful than the carborated model? This is my first Goldwing. Ride safe...Rusty

I think the sei is a lot faster than the carb bikes I rode a 84 1200 carb from IN to Cal a few yrs ago since I love speed I opened it up a few times on the interstates. After getting my sei I love taking it up in the upper rev's were it really comes alive. I have not had any trouble keeping up with 1800's I'm sure if you put them side by side the 1800 would come out on top. But just by pulling out on the frwy's with some 1800's I have been ask a lot what have you done to that 1200. Not to many guys have even heard of the sei they just think it was another model of the 1200. When you tell them it is fuel injected they laugh but when I pull out on the road & keep up with them then they want to look at it. I would love to take it cross country but with parts so hard to find I am going to sell it & get a early 1800 to pull my tear drop trailer. The sei came with a small trailer here is a pic of it when I bought it
I need to paint the frame on the trailer & put new tires on it then it is going up for sale.I would love to keep it just to ride on the weekends but I have to many other toys to have more than two goldwings. This is the tear drop trailer I want to pull cross country. Hope you get yours back on the road & enjoy it.

NOPE .... they sure aren't .... sorry. All that you describe, keeping up with 1800s, etc ..... any good condition 1200 will do.

They are very pretty bikes .... I love the SEi ...... but parts are hard to find as they were a limited production model and there's a 49 state version .... and a Cal version .... and then there are the '85 LTDs that are yet different again.

That trailer is cool! Is that vintage or home built? How much does it weigh?
Yes, I am concerned about parts availability also. They are old bikes now but I like old stuff. I wonder what Honda rated the HP of the SEi, compaired to the Asp. Hmmm

I think they rated them the same ..... carbs will make as much HP, FI just helps with drivability and emissions. High costs is why Honda didn't totally leave carbs .... and even went back to them at the time.


Here are some 1/4 mile times lifted from various motorcycle publications back in the day:
Some Gold Wing 1/4 mile times

1975 GL 1000 12.95
1980 GL 1100 standard 13.18
1986 GL 1200 interstate 12.67
1985 GL 1200 LTD 12.88
1988 GL 1500 13.06
1996 Valk standard 12.37
2001 GL 1800 12.87
2004 GL 1800 12.71


Somewhere I have a more comprehensive list .... the '84 GL1200 Standard was the quickest through the 1/4 .... but then it was the lightest 1200. All the 1200s had a 7,500 rpm redline that if used, results in some pretty brisk motivation.

Thanks CP, When I took the SEi out on it's first run it felt like it was no faster then my Yamaha XS750. I was right, the Yamy will do 12.9 in the quarter. I still have my 750 but something happened to it over the years. It shrunk! ;)

I was told it was a 1939 when we got it but so far I have not found any real info on it. I have seen a few that look a lot like it & they were told they were built from mid 30's up to the late 50's. So I'm sure its vintage just not sure what yr. really, the stove that is in it dates from around the same time. We just fell in love with it & can't wait to get it back on the road again.
