time for a progress report and another question

Postby RexAubrey » Thu Jun 16, 2011 12:50 am



Ok, a little background on my Goldwing. First owner bought it new and kept it for 13 years putting an average of 2,100 miles a year on it. Second owner bought it in 96 and put a total of 26 miles on it in the last 15 years. I bought it 1 month and a little bit ago.

So far, I have replaced the timing belts, radiator hoses, fuel lines and filter, oil and filter, rebuilt the carbs, and am now rebuilding the brake calipers (waiting on rebuild kits to come in to finish the job). I have ordered a set of 4 vacuum gauges to do the sync with) replaced the dog-bone fuse with a water tight 30 Amp fuse holder and fuse.

Today I went out to the bike and started it up to see how it is still running. it imeadiately started and the rpms ran up to 6k. Started to adjust the idle speed and got it down to 1k (needed for the sync when gauges get here). It held at 1k rpm for about 1 minute then dropped down to about 600 rpm and threatened to stall out. readjusted to 1 k and it stayed for another minute then raced up to 3k. Tried adjusting again and got the same results down to 1k for a minute then dropped to about 600. readjusted to 1k and after a minute raced back up to 3k. this went on over and over again till i decided to send this post.

Question: Does anyone know why this engine will do this or how to fix it so it will hold at the 1k RPM? I am a little frustrated with it now so i walked away and decided this was a better use of my time right now. I did do a bench sync on the carbs and the adjustment screws are currently turned out 3 turns as recommended in the maintenance manual.

Thanks,

Rex

What fuel was in it? I trust you drained and replaced it with fresh fuel? It's possible you've got sediment going through your carbs, intermittently blocking ports, alternately starving supplying the engine with fuel. You might want to run a can of Seafoam through it to see if you can clean some of that out.

I would also suggest riding the bike (assuming it's now rideable) for a good hour or two before syncing the carbs, just to let everything "settle in" after its long rest - otherwise you'll likely find yourself having to sync the carbs again in the near future. The carb sync is very sensitive, and very small changes (i.e. blocked carb passages) will throw it off.

It did have old fuel in it when purchased. I completely drained the old fuel out and put new fuel with seafoam in it. I let that set for a week and drained about half the gas out via the petcock. tank was pretty clean due to it being kept full over the years. Drained gas appeared clean (no noticeable sediment). Refilled tank with new gas (using drained good gas in the lawn mower). New fuel lines, filter, and complete rebuild of the carbs should have taken care of any bad/dirty gas situation.

As far as riding the bike have to get the caliper rebuild kits in first (not good riding bike with no calipers).

Thanks to all the excellent DIY Articles here I have been able to do all the work myself and save a ton of labor costs. Friends and family that also have bikes think i am crazy for doing everything myself.

Another update and another question.........

brakes are done, went out for a test ride and hit a small rut in the road at about 25 mph and the front end started shaking like it was going to fall off. stopped and started up again and the shake went away.

Anyone have an idea what would cause that shake. I did find that all the nuts and bolts for the front rotors were loose so i tightened them but by the time i was done it was too late (read dark) to do much else. I will be checking it over again in the morning and then taking it for a test ride up to the local shop. I need to get the inspection done. If I make it to the shop with no problems i will have them inspect it and give it a once over.

I would appreciate any ideas of what to also check in the morning before i go on the trip to the shop.

Thanks

There are quite a few things that can cause a front end wobble like that:

- worn wheel bearings (front and/or rear)
- worn steering bearings
- worn/loose shocks
- loose/incorrectly installed/torqued axle bolts, axle holders, etc (front and/or rear)
- loose wheel assembly fasteners
- loose/worn swingarm pivot pins/bearings
- worn tires
- tire pressure

First thing I would do would be to put it on the center stand and give the front end a good push/pull in every direction to try to identify any free play.

Mine did that too.After checking everything WingAdmin suggested ,I found the nut that is on top of the upper triple tree bearing was only finger tight.Had to remove the handlebars,upper tree and jam nut to get to it.Torqued it to 10 lbs(after clean and lubing the bearings)and the death wobble quit.

Absolutely check everything and torque to the specs.The death wobble will scare the be-jeesers out of anybody.

Virgil and Wing,

Thanks, I found the problems. Loose bolts and tire was way under pressure. fixed those two things and took it for a test ride and it rode like a dream. last thing on the list is the front fork seals. when they come in along with progressive springs i will finally be able to get the inspection and get on the road. Gotta say DIYs helped a lot. It would have taken a lot longer if I had to save money to have all the work done at the shop. Oh yea, finally got the idle to level out a 1k. it ran on idle alone for an hour today. i will sync it after i put a couple hundred miles on it.

Wingman lists the pivot bolts on the swingarm, I had a slight shake at the front and when I replaced my rear shocks with progressives it stopped it..Wow..I was surprised..glad you found the problem .. :D it's usually up front..

When I put new tires on my bike last year, it developed a scary weave above 60 mph that got worse as the speed increased. I finally tracked it down to the fact that a previous owner had installed the swingarm pivot pins BACKWARDS - the left one was on the right side, and vice versa. The old tire, which was worn pretty flat across the middle, tracked well enough that the problem wasn't apparent. The new tire, with its nice new round profile didn't have that forceful caster of the old flat tire, so the swingarm problem came to life.
