Title: The KZ750 Saga continues.... and how to make Parker Cry
Post by: thejij on September 16, 2012, 10:51:36 PM
So Parker messaged today, and said come on out after work, we can remove your engine and stuff... okay sounds good I say.

First.. stop for beer, mandatory when fixing bikes... then parker needed to fix the stand, so he welded the piece back on. (yah i broke it, revenge i guess lol) So we start removing parts, let me tell you how fun disconnecting that shaft was .. wow good times. Okay engine out, lets take it apart and get to the rod bearings and crank.....

We didn't quite get the engine split apart... altho we did have a few beers, sang some classic tunes listening to hair nation... and laughing about other things... anyway... the pics will speak for themselves.... the last couple are what made Parker Cry. At least I cleaned the last pic, so you all will know what it SHOULD look like lol....

Bummahs... so what is that clogging the pick-up screen? It looks like cardboard or seaweed or ?  Is that what shut the oiling system down, thereby seizing the crank?  Or is this detritus metal,  the result of the crank hammering out the bearings?

I classed it as "gunk" however it was very plasticy (is that word?) So yeah.. thats what was shutting the system down, also would seem to be why my engine got really hot, really fast !!!

Tonight Ill split the case, and see how far i can get.. and also see if I can find any other buried treasures...

I have to give Parker credit here... he keeps me level and says.. we have a plan jer.. dont worry. I keep hearing Hans in my right here... "hows the fire insurance on it?"

HAH

That's fugly.  That looks like what happens when oil and water emulsify, turns into a nice sludge that has little lubricating properties and good pluging properties.

Post by: thejij on September 17, 2012, 10:45:43 AM
agreed ! fugly !!!

However, those arent the words that Parker used... i wish I had a camera rolling when we found that... his reaction was priceless.

Pass a magnet over the gunk and see if there is metal in it.  I once pulled a pile of metal shavings from my CB350 engine only to discover that it was aluminum.  That narrowed down my analysis to finding the only likely source for aluminum shavings; the cam chain running loose enlarged the passages in the barrel.

If its non metalic, I'd sure be interested in learning what caused that.  What a fugly mess.

Peace & Grease, Dennis.

  Appears you have a good candidate for a boat anchor. Starving the engine for oil like that there is sure to be more damage that has not yet made itself apparent. Could spend a lot of time and money rebuilding  only to have something else go. Just my two cents worth. Cheers.

Oh its down to pieces now..... ive gone this far... might as well try and see what I can do... cant accept failure at this point.  Plus Im learning tons.... like tonight for instance.. im learning I need to find a new crank !!! HAHAHAHAHAHAH its only laughable now... cause im over the intial shock of all of it... now its just humor and learning how to fix it put it back together...

Will post tonights case break and rod bearing pics later... need shower and then to eat... talk soon !!!

I'm still amazed at that wad of goo; particularly what it is, how it happened, and what we ALL can learn about avoiding something like that in the future.   Fast 1, have you ever seen anything like that before?  Other than a pack rat climbing into the engine to make a nest, dying and rotting (saw that in a gas tank once) I am still in awe at what would cause that complete goo'd up blockage.   Hans speculated an oil and water coagulation. 

Jeremy: your new found urge to chase this to the ground is what this hobby is all about. You will learn so much, and in sharing it (especially with pictures) with the rest of us, we will learn along with you.  While the end game is a functional motorcycle, enjoy the journey getting there.  Believe me, when you have this engine purring like a kitten on your lap, you will experience the sweetest pride and sense of accomplishment that only comes from perseverance.

Peace & Grease, Dennis

Good news.   I am hoping that you or Parker take the mystery sludge to the college for an analysis.

In the mid-eighties I was the maintenance man at Camp Trapping.  One of my jobs was to maintain an ancient crawler tractor for plowing the parking lot and road into camp.  We knew the machine was on its last legs.  Someone suggested that we take an engine oil sample to to college.   The report received was to not run it again.   They said we would need its last minutes of life to load it on a flat deck to take it to the steel recyclers.  Thats what we did.   

Peace & Grease, Dennis

so... tonight was a good night for the "frankenwhateverparkeriscallingit" spoke with Paul this afternoon, ended up going over to his house with parker.... and we found a crank. We found it in an engine that Paul had tucked in the corner... so.. we spent a couple hours tearing it down and pulling the crank...so now i have a crank, and rods, bearings to put in the bike, along with an oil pump...

Tomorrow I will spend the day at parkers and we will get it cleaned up and all ready to start building again....

big thanks to Paul for the parts !!! and to Parker for hangin in there with me... and twylla for letting him too !!!!

World English Dictionary
spectre  or  ( US ) specter  (ˈspɛktə) 
 
? n   
1.  a ghost; phantom; apparition 
2.  a mental image of something unpleasant or menacing: the spectre of redundancy 

A bike this bagged had to have had an owner who knew about it or was a  moron.  (Yes it still 'ran' when you got it, but it was terminal)  Some people will sell their souls to the devil for a few hundred bucks.

yes, im sure this guy knew something.... I chalk it up to a learning experience now. If it weren't for this club, I would be lost in some land of unknown motorcycle tinkering... and besides the whole mechanic thing... i have made a couple good friends as well... what else can you ask for!

So to me.. its a positive thing that was suppose to happen and at this time in life.

I'd say well done all around, great attitude turning a bad situation into something possitive.  I do commend those who helped/are helping you out of your nightmare, without them it would not be the same obviously.  So nice to hear of this.

PS the clock on this site is off by 1/2 hour if that matters at all...:)

  I blame the cases being so clean and shiny, but your right- there they are. I hate that when things are going well and you realize something was missed 3 steps back. Do over rewind ughh! CHEERS.
Title: Re: The KZ750 Saga continues.... and how to make Parker Cry
Post by: Rusty Bucket on November 03, 2012, 08:37:39 PM
Interesting that the bevel-box for the shaft drive appears to be a bolt-on addition to the cases - not that it could be transferred around to chain cases, but for someone considering an out-there re-engineering type of build, the possibilities are interesting.  Were there o-rings for the oil galleries between the case-halves like a Suzuki?  If so, were they hard to source?

  Absolutely;  you two are to commended on your perseverance...

Post by: fast1 on November 03, 2012, 09:00:32 PM
   Not to be picky or anything but now that the kids are in bed and due to my missing the missing rods I took a closer look at the pictures. Don't see any pre assembly grease for the bearings--hopefully just out of frame? Initial start up lubrication is very important.  There is a ratchet on a case screw. Just to run it in I hope. I cheat by using mechanic's feel on a lot of things but not cases, cylinders or heads. Torque wrench. Here's an old indian trick for you. Get some wide long elastic bands. Assorted bags can be had at the dollar store. Slide them through the piton pin rod journals and loop them around the cylinder studs. Now you can roll it over like crazy without damaging the rods on the cases. They are actually very sensitive to this. The long thin rods on a harley are so sensitive that one good knock on the case and they are out of true. In layman's terms, bent. When you get there I have the most wicked ass cool set of 4 ring compressors you can find. You may borrow them if you like. CHEERS.
Title: Re: The KZ750 Saga continues.... and how to make Parker Cry
Post by: thejij on November 04, 2012, 04:24:43 PM
I left the ratchet on there for Hans to hand torque.. we dont trust parkers torque wrench at all, after breaking 2 of my bolts already.

Rusty, we ended up using the ones that were already in the case, they were in good condition, so we made sure they were clean and put em back....

Wayne... the pregrease.. im sure will be done.. Parker is pretty good about making sure things are pre oiled and greased before we assemble.

The piston ring compressors.. yes we will probably need to borrow those ! thanks for the offer !!!

Post by: madmac74 on November 14, 2012, 07:18:13 PM
 So once Jeremy gets a top end gasket kit, we'll need the Ring compressors Wayne.  As for pre-lubing the bottom end, Everything was covered in fresh oil before assembly, like slobbered. I remember reading someplace that the assembly lube can actually harm things during initial start up because its a bit too thick and doesn't flow through the oil  galleries nicely. That being said, i think I'm out of assembly lube ! ;) I guess my red oil can didn't make it into any pics. THAT is for sure just out of frame  ;D

Post by: thejij on November 15, 2012, 06:55:50 PM
I ordered it tuesday night... so im hoping it will be here tomorrow.. i just ended up getting a whole gasket kit, that way if you need anything for your bike (to stop your leak) then you can just take from that. I only need the head gasket, and it was still cheaper with shipping to get the whole kit, than to order from Cycle North.

Sad, that we cant support our local companies because they overcharge !

I need to call wayne to see if he is still in town... i forgot the other day, got busy at work.

Post by: thejij on November 18, 2012, 01:03:05 PM
Gasket kit is in ... heading out tonight to do some work on it. Hopefully have it almost together tonight....

carbs will be next.... then remove that fairing and install superbike bars... hrmmm.. i gotta order some I think.. unless someone has some handle bars here in town.

  I will be home Tuesday night if you want to wait for the ring compressors. I also have a couple of straight low rise bars, either of which could be had for a pint of beer. Health and hapiness.
Title: Re: The KZ750 Saga continues.... and how to make Parker Cry
Post by: thejij on November 18, 2012, 11:35:51 PM
sounds good wayne... we will wait for the compressor rings.

And Ill take you up on the handlebars as well... pints of beer can be purchased no problem !

Today was a good day.... We got the engine completed, just gotta hang the carbs, exhaust, and and some electrical work... Why you ask? I cause we removed that awful fairing and the handlebars and put on some super bike bars. It's looking good.

went to my parts store today.... er I mean Pauls house to get some lights and stems... did a few little minor things at parkers and just before iI left... We decided to start it again. started right away and made me smile... as well as Parker. I'm pretty stoked and proud we got it resurrected. so just do the lights... New throttle  already in mail and then figure out the exhaust leaks... here is the video from today.

  That is a much nicer motorcycle than the one I met last fall! You should be proud of yourself. All the stumbling blocks and walls you ran into with this bike would have made most guys give up, maybe you should change your username from jij to stubborn and diligent. Good thing is now ya' know exactly what you have. Looks and sounds good.  Congrats and CHEERS!!!!

Jij stopped by my place on Saturday.  The bike sounds even better for real.  I agree with Fast 1; his bike shows what you can do if you simply keep at it.  A nod should go to Parker also.  I don't know if they knew each other before, but it was pretty big of Parker to jump in and offer so much assistance. 

Peace & Grease, Dennis.

you are correct dennis, however parker deserves more than a big nod... I did not know him before, he did step in and offer help, and my bike took his garage over all winter... the best part for me is, we have become very good friends.

I am happy to have my bike working, but all that aside, im much happier knowing i have made a good friend. :) team sanji !!!
