750 TSCC Rebuild or Replace?

[Rich82GS750TZ]

Thanks Ed. That’s very helpful and encouraging. For now my pipes seem to be in relatively good shape and there’s no real reason to change. But all good info to know.

You're welcome, Rich.

As you can see, I had a reason to change mine out.

I think I've put at least $2K into my bike...give or take a couple of hundred dollars.

I paid $475 for the bike.

It's all good!

Is that an “L” seat on your “T”?

Yes...that "Laverne" seat.

I believe the headlight is from an "L" too.

My parts bike has the correct seat...so I swapped it.

Hey Rich, what tires are you using? That looks more aggressive than my Shinkos

Ed, I have that same coffee pot. It was an emergency purchase @ $15 and I didn't expect it to last, but it's going on 6 years now.

I still have that coffee pot but upgraded to Keurig.

Hey Rich,

Look at my old pipes...they weren't drilled out like yours!

Rich,

I found a better view of how the oil filter is positioned relative to the V&H/4-1 pipes for when you upgrade! I just wrapped them to keep the oil off.

That was the one thing that I forgot to ask you about. Filter access. Thanks for the pics.

[GSXR7ED]

There's plenty of room in there to do the oil filter change.

I never did an oil change with the dual exhaust but it looks more limited as far as space to remove the filter is concerned.

Plenty of room for oil filter cover removal with stock pipes installed.


Ed, going back a comment you made about the clutch cable routing guide wire: The one on the carb rack has always been there in perfect shape. It was the one that gets bolted to the valve cover that I was missing so I fabricated one. Where I failed was the cable guide I made pushed the clutch cable into the path of the throttle linkage between #1 and 2 carbs, even though the clutch cable was properly set in the carb rack cable guide. The new motor came with the valve cover guide. I triple checked the routing this time.

[GSXR7ED]

Oh, yeah! I forgot about that guide wire on the valve cover.

The dual pipes are positioned in a way to allow easy access to the oil filter chamber...which is good for you!

I am very Happy to report I now have a bike that I believe is better than it has been in at least 30 years. I’ve owned it for the last 15. It has never run nor looked so good.

Big thanks to all who helped me with this (for me) Huge project. I had never actually seen a real live piston before. Much of it was daunting. You all really helped me through it.



To recap: on March 23 I destroyed my engine, or at least half of the rockers in the head, due to me routing a new clutch cable incorrectly and interfering with the throttle linkage. Afraid of what I’d find tearing down that engine, I was able to source a nearly identical mileage engine from fantastic forum member Storm64 (Norm).

I cleaned that engine, honed the cylinders, installed pistons and rings from original motor because they were in better shape. New gaskets all around. Painted the frame, reinstalled the engine.

While I was at it, installed an AGM battery and cleaned every electrical connection.

A few loose ends: still waiting on triumph connectors for the SH775 that I had previously installed. Will redo all the connections around Stator/RR/battery/fuse box. Not because mine are bad, but because with the right connectors and tools, I can now make them better.

Have also been waiting for 3 weeks for a partsoutlaw order for new choke and throttle cables, and new Cush drive wedges.

I still may completely tear down the original engine and rebuild it and make it really pretty. So thinking vapor blast everything maybe. Paint. We’ll see.

Pained the frame? A double entendre if I ever saw one

See, nothing to a simple top end refresh

Did it give you a chance to buy new tools?

er...Freudian Slip? Anywho, “nothing” to you and a lot of others, I’m sure. Kind of a big deal for me. I consider myself moderately handy, but a mechanic, I am (was?) not.

Tools I bought due to my idiocy that caused this calamity (that I can recall without reference it my eBay and Amazon orders:

Impact screwdriver. The type you hit with a hammer. (don’t know why I never bought one before, WOW!)
67mm cylinder hone brush.
Piston ring spreader.
Terminal Crimper from Vintage Connections (used once still practicing).
Soldering Iron. (used once still practicing).
and a whole bunch of scotchbrite pads and WD-40 for cleaning gasket surfaces. Should have added up the hours I spent doing THAT!
