Title: 1968 Suzuki T500 Cobra
Post by: Sonreir on Feb 05, 2016, 15:00:48
Picked this baby up last year and it's been sitting in my shop since then. Been going back and forth on what to do with it. Given that's it's a first year T500, I've settled on a full resto, as close to original as I can do.

Most of the parts are there, but I'll need to track down a side cover and some badges. The crank cases have a crack, so I'll need to get that repaired and there's a bit of surface rust, but most everything looks OK. I'm hoping most of the work just needs to be aesthetic.

Currently working on getting a lost title and clearing out a few bikes in the shop, then I'll get to work. Updates will be slow as I have a lot going on, but I at least wanted to get the thread going.

Going to get the crankcase welded? There's 2 sets on ebay, one with a chunk missing in what looks to be the same spot as yours.

And this one. Pretty pricey but looks to be in good condition

I finished up tearing down the engine last night.

Transmission looks pretty good to me, so I maybe got lucky on avoiding the dreaded fifth gear oiling issue? Speaking of which, I'm supposed to make some modification to increase the oil capacity. Anyone have the details?

Looks like the pistons are already .5mm over, so I'm not the first one to open her up.

I started clean up on the oil lines and oil pump, too.

I also took the opportunity to order a stud extractor and a impact wrench so I can pull the last of the head studs that broke my wrench.

Post by: farmer92 on May 11, 2017, 15:41:28
In the lower crankcase, there is a small dam sectioning off a corner of the case. This is where the oil check screw is. The dam is raised so that the oil must be filled to a higher level before spilling over into that section and then out the check screw.

Title: Re: 1968 Suzuki T500 Cobra
Post by: Sonreir on Jun 06, 2017, 15:08:54
They're going to be painted to look as close to stock as possible. The vapor looks really good when it's fresh, but it takes a ton of work to maintain bare aluminum.

From what ive read it doesn't corrode nearly as fast though as the process helps seal up pores. If you keep it clean until it forms the clear aluminum oxide layer again it will also be much more sturdy. You just gotta let them "rust up" haha

More welding on the upper case.

I also refurbed the left control switch. This switch is one I got off eBay for a later model (the '68 switches are very hard to find), so I didn't want to put too much effort into it, since I'll be replacing it with the proper ones at some point.

I disassembled the whole switch and cleaned up the contacts and the housing. The wiring all looked good, so I didn't mess with that at all. A couple of hours in the tumbler, some soap and water, and then a light buffing is good enough for me.

The same principle applies to when you insure your bike, weather goes for a dump.  If you had not polished the one you have, this would never have come up for sale.  It's the "Completion Backwards Principle".

The engine is just about done. Powder in most places, but the side cases were doing a weird outgassing thing and screwing up the finish. They've been stripped down again and they're currently bare. I'm going to see what I can do about finishing them in some other way. I don't really feel like polishing aluminum every few weeks for the rest of my ownership period.

it should on the self cleaning cycle, Or maybe a gas grill. My Little Weber will hold 600. Just cool them slooowly... reduce the temp to 400 then 200 then turn it off....
Title: Re: 1968 Suzuki T500 Cobra
Post by: cxman on Jun 26, 2017, 21:14:18
eric they are not pure aluminum they are some alloy

i baked them at 550 for 1.5 hrs the last time i tried it and they still came out like you had sand under

the powdercoat

the big right side cover came out ok but the 2 small left side ones were almost as bad as the first time

so they have been baked 3 times 400 for 1hr no go 450 1.5 hrs no go then the last time 550 i hr

i think its the alloy

the powder is bonded ok just keeps pitting the finish on the full cure of 400 degrees for 20 mins part temp

i have never had this with aluminum
Title: Re: 1968 Suzuki T500 Cobra
Post by: irk miller on Jun 26, 2017, 22:59:44
Not sure were talking about the same thing.  My understanding is at this point he's trying to get all the oil out of the pores of the alloy.  550°F to 600°F is what temp you have to reach to burn off carbonaceous material.  As far as powder coat, I won't reply as i have too little experience.
Title: Re: 1968 Suzuki T500 Cobra
Post by: cxman on Jun 27, 2017, 07:59:54
the powder coat is going on perfectly and in the flow out (250-300) looks perfect

it is in the full cure that it get these sand grain looking patches coming from under neath

i was leary of heating them up more i will talk to matt about it today and see if he wants me to try it again before i ship him the motor back

as my over can go to the 600

I don't really feel like polishing aluminum every few weeks for the rest of my ownership period.

if you take it to a mirror finish i have found a good polish once a year is all it takes to maintain it looking good.

Indeed.  And it doesn't take removing the part and getting friendly with the buffing wheel(s) again, just some hand polish (blue magic, simichrome, wenol, etc) a cloth and a little time and elbow grease.  Unlike pretty much EVERY other treatment (anodizing, chrome, paint, powder, etc), this actually lasts indefinitely as long as you actually maintain the surface. Actually pretty easy, and for me in the same range as cleaning - polishing - waxing your tank and side covers.

Painting is probably going to be the only solution; I found that Tremclad Hammertone Silver gave a pretty good approximation of the silver paint used back then.  Used it on my Kaw G3TR and Hodaka restos (Super Rat, Ace 100) and looked pretty much like the factory colour on both makes.
Those side covers have a huge amount of "reclaim" (ie., scrap metal) in them - like most if not all '60's Jap side covers (they were probably still melting down WWII scrap metal LOL) and you will probably always have the problem.
I stripped the factory paint and polished up the side covers of my '67 Yamaha 350 and ya, they polish up pretty good but... they have light and dark shades going through them - pretty disconcerting to a 17-year-old, who was expecting beautiful gleaming alloy like I saw in the bike magazines.
Great resto - you have (a lot more) more patience than I.

Before and (almost) after of the front fender repair.

Dent removal, welding, and most of the sanding is complete. Still need to buff it and them off to plating. We were originally going to go with chrome plating, but it turned out to be cost prohibitive. We're now going to be doing bright nickel instead. I'm told it requires a little more maintenance in order to keep it looking good, but it's hard to distinguish from chrome as long as you don't let it get too dirty.

There is a place in Quebec here that used to build motorcycles they did a lot of nickel plated parts I always thought they looked like they had a slight yellowish tinge to them.

It still looks sharp it's just something to keep in mind

Typically, automotive chrome is a nickel-chrome.  It's nickel plated first, then flash chromed for the brightness and resistance to oxidation. Most nickel is nickel-phosphorous. That's where the yellowishness is coming from.  If the whole bike's chrome is nickel plated, then I think you won't notice as much.  If it's a mixture of parts, then I think the nickel parts will be pretty obvious.

Also, it should be noted that in order to nickel plate you have to remove the chrome plating.  There will be be poor adhesion otherwise.

We're replating everything, so hopefully it's not too noticeable. Maybe it'll be a feature or conversation piece...

Title: Re: 1968 Suzuki T500 Cobra
Post by: Sonreir on Jul 03, 2017, 16:03:09
Pretty darn cheap. I didn't have to clean the parts or anything. Handed them a box full of rusty, crudy, greasy hardware along with $75 and it came back like this a week later.

I prefer the appearance of nickel, but as irk says, it's the contrast with chrome that shows.

Nickel everything!

thats totally worth it, wonder if they will take some shipped in.  I cant find a place in Indy that does small job plating for anything less than a first born.

There is a place on the east coast that does mail in plating. A shoebox cost a little more than you paid but it was the same deal. Send it in dirty and get it back shiny. I think it's Parker metal finishing in North Carolina.

About $240 after shipping. If bearings would have been needed, the price would have doubled.

Finally some more movement on this one.

Pipes arrived from the UK yesterday. Unfortunately, one cannot find OEM pipes in good condition anymore, so I've had to make a few compromises on the project. This has turned a bit more into an OEM+ kind of build. I'm hoping the pipes will still look at home on the Cobra, though.
