Her 550T

[Guest]

Picked up this '81 550T for my wife to ride, about a month ago. The owner was asking $500, but since it wouldn't start, we picked it up for the paltry sum of $200.

PO said he rode it for a few months and the carbs got better the more he rode it.

Then the battery started going dead on him. He had a friends dad change the stater that's when he noticed the oil leaks.:-k

A little tear at the seam and missing exhaust transition tin on the right side.

Overall it looks good, so were just doing mechanicals, for now.

Tank is in great shape inside and out.

Nice score Rick...

It has a few issues I noticed right off the bat. First was the starter, it wouldn't start and the owner said the was an oil leak near the bottom of the engine. I tried jumping the solenoid since all I was getting was a click, which means it's engaging, but you know you have to try anyway.

That's is the first thing to do, I want to get it to turn over to check compression. I have a spare 750 starter, so I had Bonnie(my wife) take off the starter cover. No go, a PO had reinstlled the cam chain tensioner on backwards or upside down. The cover has no room to come off.

Look at this

This isn't good, there in no way that tensioner is coming out without removing the carbs. Here is Bonnie removing the carb linkage. This is her bike so she going to do most of the wrenching.

And finally with the carbs out, we removed the tensioner and bad starter.

With the replacement starterand tensioner back in we hooked the electronics back up to see if she turns over. It does. I'm going to check the compression tonight.

Took the carbs and seperated them last night. Only one slide was slow dropping back down. I tore down 3 and 4 and have them soaking. Everything came out nicely, a rareity with the bikes I usually buy.

My impact driver removed the racks without damaging the screws.

Progress being made. I had a spare oring kit for other project bikes that will help move these carbs along swiftly. Mr. Barr I will need two more CV oring sets please.

Thanks Garth, it has some minor issues but it's a good start. Better condition than anything I've pick up before. Bonnie is going to do most of the work.

I'll still need to lower the bike a little, so I want to slide the forks up in the trees about 1/2 to 3/4 of an inch. Rear shocks that will give about an inch of drop would be nice also. The front fork seals leak a little, but book says to try changing the oil first and see if that stops it. The front tire is over sized 110/90-19, if I change it to the 100 it might help and I can take off these fender spacers.

I think this is what caused the front fender damage.

Great Find!

It's a mini 750T and I like it! You'll have this "T" back on the road soon enough and I'd be interested in the progress with pics. Thanks for sharing.

Good one Rick!

Definitely looks in good cosmetic shape, should clean up real nice!

There is also a trick of using a slice of a plastic bottle to clean the seals. Apparently gunk can sometimes build up under the seals and prevent them from making good contact with the fork leg.

Changing back to 100/90-19 will put the handling and the fender both back where they belong, but I don't think there's going to be much help for fork seals there.

The bike looks like a great score for $200. I've ridden my brother's 550T. It's a nice bike, but 6 gears feels weird.

You can buy one of those fork seal cleaners that Dogma mentioned for $5.00 or make your own out an old bleach/plastic bottle. Might be an inexpensive, temporary fix.
Worked for me.

I ment it will help bring the bike down so Bonnie can flat foot the bike. Shes not tippy toeing, but every little bit will help. I was thinking of cutting the seat foam down a little also, since the seat needs recovering. Bonnie actually likes the steped L style seat better, so I might look into that as an option. I would prefer another seat, since the T seat is in good shape and would work for me on test runs. What is the tip with the plastic bottle and the seals? IDK on the 6 speed, on the highway I wish my 1000's had that 6th like an overdrive to lower the RPMs. Especially SuzyII my 1000G, it feels like I'm always looking to shift once more. Eric has been tinkering with a later model final drive gear ratio on Goldie his 1000G.

Thanks Steve, I'll look into that. There isn't alot of oil, just more than I feel on my other bikes.

I was joking about 6th. I'm so used to not having it now, any bike that has it feels odd. I think it's almost universally agreed that a 6th gear would be nice to have on most of the GS models. Especially the bigger ones with enough torque to use it.

Before you go gung-ho on shaving the seat, the first thing to try is to simply make the front a little narrower. That will not force her legs as far sideways before they can point downward. Shaving only the sides of the front will also not affect comfort while riding by reducing the thickness of the padding. You will have to take up some of the slack in the upholstery, but should not need a new cover just to do that.

Bonnie actually likes the steped L style seat better, so I might look into that as an option.

Try shaving the front first, as the L seat is a completely different pan, and might not even fit on your (her) T.

What is the tip with the plastic bottle and the seals?

Gsrick showed the 'official' tool that you can buy, but the basic idea is to take a thin piece of plastic, like a milk bottle, and slide it down between the seal and the fork tube. Run it all the way around the fork, it might catch any bugs or small debris that has gotten trapped in the rubber seal, preventing it from sealing properly. If your forks are pitted, it won't help with that, but if it's debris that is in the way, it does a decent job.

[Guest]

Thanks for the advice. As soon as the kids finish up the milk I'll try it.

We're not going to do anything to the seat just yet. Got to get it running and stopping first, but with the right tire and sliding the forks just a little, might accomplish what is needed. She will be riding solo so the rears shocks can be set on their lowest setting also.

 

[Guest]

Enjoying the thread Rick. Nice to see a couple being into bikes together. Should be a real nice bike for her.

Dinner break, time to show of the carbs

Dinner break, time to show of the carbs

Carbs are finshed and ready to be reinstalled. Not till after we take a compression test and see if we should proceed.

Before cleaning

After soaking, new orings and polished allens and some polishing of the tops and end bowls by Bonnie........looks so much better than my photos show.

Bonnie wanted to do the center two bowls, but no one can see those. I wont be surprised to see them polished some time while I'm asleep tonight or at work tomorrow.

Tell Bonnie NICE WORK.

Rick you are lucky to have the Mrs take such and interest in maintenance on her new ride. My wife will ride her bike and fill the gas tank but she come home and tells me it needs to be washed cause she road in the rain ect. Gotta love her though, she had ridden over 14000 mile the last 2 summers.

Compression test results.

Compression test results.

Here are the results of the comp test. I tested each cylinder twice each round and recorded the best results.
First round dry 1-4 : 30, 115, 100, 125

Second round with 1 cc of Marvel Mystery Oil: 50, 125, 140, 150

Third round with 1.5 cc more MMO: 140, 180, 160, 185
Just had to try #1 again and got 5 more for 145 psi

So what do you think?
It has been sitting for approximately a year.

PS the oil was drained last night and I ran the test with all the plugs pulled.

Sweet. Just came in from throwing everything back together on the 550. Fired right up like I knew what I was doing.
Didn't even need the choke, damn I'm good.
I do have a problem though. I kinda found the oil leak the PO mentioned.
Look like it's coming from behind the clutch cable cover.
I can see it coming down the back of it down the oil pan.
Not sure where it could be coming out from behind there.
Something any of you've run across?

Not too shabby looking, for just a cleaning. I did paint the starter cover with chrome paint. Not chrome, but it looks good from a distance. If I color sanded it and cleared it, who knows it might actually look like the cap did. I wanted to get it running and test the stator before pulling and polishing the covers. Seems like it's charging ok. I have to adjust and sync the carbs still, but so far I'm very happy. We'll paint it up after I check all the gaskets for any leaks, so far it's just behind the one cover.
