Here I go again '81 750Ltd H2 Roller...kinda Thinking I might go "Industrial"

Thanks Jr.

So what did you go with, and what were the results? Did you like it, change it later? Was it the same model I'm working on?

I've been wondering at some of the extreme variances from stock that I've been seeing. I can always just replace with stock sizes, but if there are noticable positive differences to the changes, I can be sold. ;D

I have an 82 kz750 ltd, so same thing. I went with the 16-40 combo and the new 530 rk chain. I didn't notice a difference but i didnt ride the bike before and after with the chain being the only thing that changed. The lighter chain and slightly different gearing was supposed to make a slight difference but probably one ill never notice.

Fun with Science, you say? I don't suppose you put it in a thread somewhere I could check out? Sounds really cool. Also sounds like something that could give birth to a baby Godzilla if I pooched it...

I havent made a thread. I have done everything from old chrome plated fasteners, fire damaged guns to bike parts.
 
That's awesome Fury, I might pick up a book on plating, and give it a go!

Thanks guys, yeah the pipe is coming along, although the chrome's not in the best shape up close. We'll see how it ends up, I might still wrap it. Or maybe get it re-plated if I can do it cheap enough.

Going to see an upholsterer today, we'll see where things fall out as far as skill, attitude and price. Wish me luck! Going to start the carb teardown as well, I say "start" because I have 10 carbs to do. :eek:
 
Okay, that's IT!!! The whole world can go and choke on a bag of dicks.
Bike's got a new name:

BAD NEWS

Turns out that my tank is pin-holed after all. Time for a new tank. Kinda knew it was coming, but still. And I just ordered a petcock rebuild kit, too.

My front seat pan is completely rotted out on the left hand side. Probably due to exhaust gases from the battery. Overflow hose mighta helped that. I found out just before I went to take it to the upholsterer this morning. Still went, and hashed out a cool design for the seat, just as soon as I source a new seatpan. Anyone got one they'd care to move? My pillion seat pan is still good, and the foam is manageable on both, so even just finding a naked OEM front pan would rock my little world.

And the carbs. Oh my, the CENSORED CENSORED CENSORED carbs. I'll post some pics tomorrow, when I won't be tempted to just torch the whole pile, and cleanse it with fire. I've got a few sneaking suspicions about these particular carbs, and if I'm right, CENSORED must pay. I'm seeing what I'm pretty sure is either Locktite, or some kind of silicone sealant in the threads of some of the bolt holes. Neither one will lead to my having a pleasant afternoon. Hit them with enough Deep Creep to skin the panties off a nun. Hopefully I don't have to get too aggressive with them. I've already killed one manual impact driver, and I'd rather not make it my thing.
I just can't believe how many issues this bike has, all of them relating to illiterate lazy donkeys. Read a goddamned book why couldn't they? Maybe a manual, that would've been nice. Seriously, I'm puzzled by a few of the choices that have been made with this machine by PO's, (and not just the evil black paint, which I'm pretty sure is some sort of alien creature, manifesting itself ever further into my reality) what the Hell were they thinking?

Oh yeah, did I mention the spider nest that hatched from somewhere in the bowels of the bike? Yup, hundreds of the bastards. Literally. Swarming all over their evil bastard webs, that they had strung up all over the front end of the bike and off into never before noticed corners of the shop. My, how I loathe spiders. I thought I did before, but that was nothing compared to the icy hate, for their eight legged little asses, that now courses through every fibre of my being.

Oh well, just one of those days, I guess.
Bag of dicks all around.
 
Seat Pans & Spiders & Carbs, Oh My!

Okay, got some sleep, there's actually some sunshine outside, and I'm incredibly on my second day off this week. Unless I decide to go into the office this evening, which I should, but Jesus am I done with taxes!
Besides, my Fabrication manual and my Caswell kit came in today. I'm ethically and morally obligated to read the manuals and perhaps even log a little shop time. Maybe even check out the new Captain America movie...

So here's the pics:
Seat pan's CENSORED, but I have a replacement on the way, and an upholstery guy lined up.




Here's some close-ups of my little stowaways. Picture this, only all over the front end and trailing off to far flung corners of the shop.
It was like a really bad version of The Mist. I would have taken more pics, but I was busy defending myself, in a ball, in the corner, with my eyes closed ;D



And here's the carbs. I'm wondering why someone would cap off three vents and plug three float bowl drains. Too lazy to set the float height properly? If there's some logic to this, please let me know, it's troublesome. I'm wondering if there's a safe way to open up the drains again, (probe, drill or punch?) or if I should just get new float bowls. I already have SS Allen bolts on the way and carb kits for a full rebuild. I guess I'll be needing some T barbs and more 3/16", (is that right? 3/16" for the carb lines?) fuel line, as well as clamps, too.
The red stuff you see under the too long, mismatched bolts is the mystery crud that has me wondering just how CENSORED an experience this is going to be. At least everything moves freely, although the throttle cable holder seems to be slightly bent out of true, and the throttle cable mount is damaged, (seems like it should hold, though).





So the shopping list seems to be pretty static, although some new items were purchased as I went along:
Re-upholster seat
Chain & sprockets
Tires
SS brake lines?..
 
Well, this is frustrating.

Got a seat pan on the way from the East coast, got an upholsterer lined up. But still no love for a tank, I could get the pinhole repaired, but I just don't trust it, the thing is a rustbucket/firebomb just waiting to happen. The only ones I see on Ebay are going to cost me around $150-$200 once shipping is factored in. Sucky :(
 
Rotating on the horns of a dilemna

I have a line on a KZ750 Ltd tank. It would cost me about CAD $175 with shipping :mad:
It's for an '81 and has the stock paint intact, black with gold pinstriping. However, as I've mentioned before, I can be a little ocd and it would drive me batshit to have the wrong year original paint tank on my ride.
I'm also kinda hung up on the whole bare metal tank thing now, too.
However, I would almost consider it sacrilege to strip intact original paint, especially in light of all the difficulties I've been having in locating a usable tank.

Damn it, damn it all to Hell!
 
Does anyone know if a '80-'82 KZ550 Ltd tank will fit properly onto a '80-'82 KZ750 Ltd frame?
There seems to be a few of these floating around for a reasonable price and in a condition that I won't feel bad about stripping down.
 
Well well well, good news, in a weird way.

Got the tank, the paint is far from perfect, (funny that I was actually relieved that the paint wasn't intact) but no dents or dings. So bare metal, here I come 8)

Seat pan is in, dropping both pans off at the upholsterer on Saturday, so that's another gremlin stomped. Tires came in as well, went with a set of Shinko 230's, $175 shipped, they'll do for now. Grabbed some stripper, primer and paint from good ol' Can Tire. So we'll see about prettying this girl up after we see about getting all the king's horses together again, and then apart again, and then together again at last.

Got engaged, got a tattoo, got half my face drilled, pulled and stuffed by a demented dentist with an antipathy towards painkillers, finished my contract, agreed to fill in for an additional month, (dumbASS!!) so I haven't had a chance to do a damn thing to the bike in weeks. Fiancee's b-day is this weekend, so it'll probably be at least next weekend before I get any wrenching done. Totally stoked and kinda nervous about how my little plan is going to come together. Worse comes to worst, I break it down again and start over.
 
Woah slow down...weld the hole in the gas tank....i have filled them before with a mig ....kinda sketchy but i filled the tank with water and did it anyways
 
Too late Desmo! I already have the tank, (although I'll be having the old one welded once I get the dents out).

I'll finally be finished the tax job tomorrow, (unless the bastards offer me another raise and some full-time work) and then it's gonna be all motorcycles all the time. Except when I'm at the gym or putting a smile on the fiancee's face, that is.

I decided to take the plunge this year try to make a go out of some light work on the bikes. What I can't manage in my tiny shop I can source out, been dabbling for a few years now, may as well use it to subsidize my habit. Be great to love my work for a while.

Going to be a marathon session trying to finish up a website, (turns out I hate web design, wish I had the cash to hire someone) and get a bike together for a charity run this weekend. Wish me luck!
 
All bow to the mighty Ultrasonic Power!! :)

Well I got my carbs separated and two of them busted down, (almost, looks like the PO busted off the top of the primary main jet in one of the carbs, unsure how I'm going to approach getting it out, or even if I should) and in the ultrasonic cleaner.

Thing's well into it's second 30 min. cycle and still only at 35 degrees. Seems to be doing a bang up job though! So that's a good day.
This may present an opportunity of sorts, though. Any carb gurus out there that think I should change the jetting for the 4 into 1 Vance & Hines?

Gonna spend tomorrow reassembling, polishing and painting these bad boys 8)
 
Looking like a plan. Z1's got jets for cheap, if I'm going to get one, I may as well get four, eh? ;D

Besides, it's about time I figured out more about carbs than how to tear them down, pretty 'em up and put 'em back together.

Trying to find new float bowls is turning into a pain, though. Just royally pissed off this poor guy in Florida. He had three good carbs, and the innards for the fourth, but with shipping it was going to be US$145. Just way too much when all I really need are bowls and jets. He was less than understanding.

Oh well, at least I've got the seat and tank sorted. Figure I'll try putting what I've got together this weekend and see if she'll go. Bugger all else to do, looks like I'm gonna be single again soon, and she's off diving for the weekend. Wish I'd put that cash I used on the ring into the bike, would've gotten a lot better bang for my buck.
