Project KZ1300

[FJRay]

I have few regrets in life, but 1 of them is definitely selling this bike.

I regret getting rid of my Nighthawk 700S too. I keep looking half-heartedly for a decent one and the wife even thinks there's room in the garage for one too...

Sorry for the thread hijack! I'm following along and wondering how the hell all the parts will go back together without any left over!!

You guys keep changing the rules. My contract doesn't say anything about leftover parts. It just has to be pretty.

Don't worry about left over parts Ray. You know the factory always throws extras in there, just to be sure there's enough. Its also a scam to drive up the price. Any extras you find should be crushed and immediately thrown away.

Zilla and crew? Don't be encouraging Ray to smelter parts down for recyclable metals.. I need them parts!​

​

Ok then, off to the show!​

​

All Righty Then​

​

Ray has moved the KZ1300 to the 'indoor' and heated section of his spacious shop.​

After talking with Ray today, I think, in some kind of masochistic way, he's enjoying this project!​

Ray mentioned this is rev 3 of the engine stand. ​

​

Ray asked me my thoughts regarding replacing various gaskets, seals, bearings and what not. Instantly I recalled a previous engine rebuild I did, where, due to lack of finances, I had to use used seals and what not - and I ended up rebuilding that engine twice.

​

​

Oil pump. From the pix, wear looks minimal. ​

​

Ray, correct me if I'm wrong, but the big hole at left - is for ignition coils, pick up plate and what not? ​

​

​

​

​

Oil pan.. not too bad considering the miles...
One issue with the 79 A1 and 80A2's was oil depravation due to the shallow pan. Many replaced the pan with a later model's pan that was deeper. If I can find one, I will too. ​

​

The only real Uckkk found in this engine.. bottom of the pan. ​

​

Gearbox, shift dogs, shift drum all look ok. ​

​

​

​

Another shot of the pan ****. Actually, thinking that this engine sat for over 8 years... and has over 100k on it.. Not too​

bad. ​

​

The oil pan screen has some fibrous **** on it. Not sure what it might be.. But with all the fibrous/plastic gears, perhaps something from there? ​

​

Parts baggies are us... ​

​

Ray, what's that metal spiral winding of steel pix bottom? ​

​

Shift forks look good.. the tranny was shifitng fine up to point of not being ridden. Never hot-rodded, or shifted w/o clutch. ​

​

​

Main bearings look good too. Ray reports back that lower end rod bolts are 9 bucks each.. Do I want to spend $$ and​

look to see how rod bearings look? **** Yes! We are waay too deep not to look at everything to be sure all is well... ​

​

​

Whoever desinged this engine must have been on crack. I mean really.. too many chains, too many plastic gears, too much of too much. No wonder I love it! ​

​

​

​

​

I like this pix.. A certain beauty in the elegance of a spiral cut gear spinning next to a crude-*** hyvo chain... ​

​

.008" of crankshaft lateral play. Interesting,as this engine had a horrible growl at 1,800 rpm when I got running a year ago, about 10 years after it last ran. The stator on the LHS has wear marks from the rotor hitting the 3-phase coils to output wire connection.. and I really thought the crank was the issue.
Now I'm not sure what we have here... ​

​

Last pix - man, there are alot of parts laying around... ​

[FJRay]

Yeah there are lots of parts laying around and what you don't see are the two milk crates full of bagged parts sitting on another bench. Will be stripping everything out of the cases next so they can be cleaned up and made ready for assy. The head and cylinders should have hit the machine shop in Wa. today so hopefully will have answers next week. Stay tuned.

 

[wfooshee]

Repeating my question from earlier in the thread, this time for FJRay, he whose hands are in it to the elbows.

So if 'twere necessary to replace the cam chain, does the case have to be split? Or is there a way to press a pin out and open the chain to remove/replace it? Surely that kind of replacement part wouldn't require that kind of teardown! Would it?

 

[FJRay]

Sad but true. To replace any of the chains requires a complete tear down. It's also interesting that the FSM doesn't give any wear specs for any of the chains. The two small ones have tensioners but the two big guys don't.

 

[dcarver]

Hey, at least I'm keeping Ray with something to do during those witch-*** cold La Pine winters! :rofl:

 

[FJRay]

It's ten degrees warmer this morning. All the way up to 17 degrees. No KZ news today it's my payday so it's off to costco, walmart, home depot and the gun store for reloading stuff.

 

[Bustanut joker]

The stuff in the oil pump screen is Frito residue... Damnit Ray. You eat with oily hands too?

I was thinking, with all those chains, if you were to separate 'em into links? I bet it would stretch from Rays to your place Don.. Man that's an assload of chain in there!!

 

[wfooshee]

Those drive chains just kill me. I keep asking, "Why not gears between the shafts?" Only thing I can come up with is that the gears would be larger diameter than the chainwheels, and they didn't wanna make room for them. Gears coulda been a lot narrower, though.

 

[dcarver]

Even back in the day, all the mag's were critical of the 'excesses' involved with this engine/motobike. Too big, too heavy, too phat, too complex, too much. No wonder I fell in love with the bike, I love excess!

 

[not2shabby]

Dayum! Glad I started out with a DR350 for my first rebuild. This beast is beyond complex! That and it would take up 3X the garage space!

It's just a 350 on steroids! Each cyl is just 216 cc's!

So is that why I'm working on it.??????

No updates this week cause I'm in Vegas visiting family.

The twins say hi Richard.

 

[Fairlaner]

hehe Nice Ray Nice.......say hi to the twins from me....

R

 

[dcarver]

Richard always gets the love... even though he can't recall what color eyes the twins have! :rofl:

 

[Fairlaner]

Eyes?

R

 

[FJRay]

Richard always gets the love... even though he can't recall what color eyes the twins have!

And you can??????????

 

[HotRodZilla]

Mmmmmmmmm...Twins!

 

[wheatonFJR]

No twins without pics. Didn't happen.
