750 TSCC Rebuild or Replace?

[Rob S.]

That poor glove! Can it be saved?

And that's your passenger foot peg support, right? Was it damaged?

[Rich82GS750TZ]

Thing is, I KNOW to not wear gloves when working close around spinny tools like a drill press, especially with a wire wheel. Yeah, time for a beverage.

[GSXR7ED]

Oh, Geeze!

Wash up and have a beverage.

I think I’ll quit for tonight.

Depending on how much time you have - I left the pistons with their stuck rings sitting in cans of paint thinners and ATF on the bench. By the time I got around to them they were all lovely and free and clean enough to lick your dinner off.

There is carbon in the ring land. Maybe some varnish too. You can try soaking the piston in carb dip to loosen. A better method is to first remove the rings though and then soak. Use an old ring, broken in half, to scrape out the old carbon. Just be careful to not scratch the aluminum.

Getting the donor engine prepped for install, I spent about 3 hours today cleaning up the base gasket surface on the block. As I’m moving the pistons out of my way I realize that #4 piston’s rings are not moving freely like the others. All rings on #4 are frozen into their recesses at their tightest diameter. I removed the ring from one side on the pivot pin (it subsequently vanished into the ether, lucky it didn’t go in my eye) and drove the pin through and removed the piston.

I assume I’ve got to replace the rings on at least on this piston. How do I get them out? Soak in PB? Do I definitely have to replace all the rings on all pistons? That’s $120 more dollars I didn’t want to spend on this engine.

Good times!

Thanks for sharing.

I told you that you were going to channel Chuck Hahn

Guilty
My hand is all cramped up today from spray painting.

Looking good

Look what soaking these in vinegar for a day and scrubbing with a brass brush can do. (The one on the left)

[Rich82GS750TZ]

Covered all the rusty bits the other day....


I’m fortunate to have a big paint booth at work to hang and paint all the pieces.

[GSXR7ED]

Wow, you're getting serious about this bike.

Very true...I have a thread called “breakdown” but it is nothing compared to what Rich is doing.

Every nut and bolt’s been wire wheeled, bagged and tagged...
I’m trying to keep everything as organized as I can.

That's the easy way. If you were up for a challenge, you'd skip the tagging, bag them all together, then give it a good shake.

You youngsters - always looking for the easy way out.
