Rear done-

You could replace those cush rubbers with the "improved" versions and no one would be the wiser.
Although there's still a few new ones of the original design like yours floating around. I got two the last time I ordered a new set from Honda and had to exchange them for the newer style.

I'll probably do that when I get one of those rear sprocket retainer or guard, or what ever it's called, my bike doesn't have one, and I think I need one to put this bike back all stock...but when I locate one, I'll pull the rear wheel again and change out the drive rubbers if they look fatigued. This bike won't see any strip action while I'm riding it, mostly just cruising with the occasional half-hearted roll on.

The "improved" ones, what do they look like or do you have a part number handy so I can be on the lookout for some to eventually swap mine out with?

Got some good news from the plater (I'm driving him nuts, he can't text very well lol), everything is done and will be sent out tomorrow. It only took 2 days to get from here (Alabama) to Cali, (amazing right?) so...and here's hoping...it'll get back here in two days, so I can start putting things back together and start going through the motor, and get to putting this thing back together.

And on a side note, my uncle made mention that he has a freshly machined cylinder with a new 836cc kit sitting on the shelf that he made apparently clear he wasn't doing anything with. I might get it from him and use that on the next one I build...it'd be a shame to try and build it so close to stock then deviate at the last minute.

I'm thinking that K0 in the junkyard (which has anthills on the motor)...836cc kit from my uncle...NOS tank...get some more parts together...and do another more performance build? Don't know if i'll get the wife on board for this one, but here's trying...I'd love to do it in blue though...the red would just get repetitive.

Super happy, just got a set of All Balls Tapered Steering Stem Bearings for $29 shipped off amazon...and in searching for the part number, I found out about Brimmer...very funny read BTW.

Here's a picture of the newer design rubber. The part number was the same for both the old style and new style ones that I received, thus causing the confusion.

That's what they're claiming, it was $29.64 shipped...that Brimmer dude got nuked out of the water...and got every bit of what he had coming, don't rip anyone off ever for any reason...the repricussions from the board are just the start of what can happen by being shady. I treasure and respect this board...wouldn't dream of doing anything like that tool Brimmer.

Kind of an up and down day for the project, I got my wheels back from the local shop, they only hit me for $31.50 for trueing the front and rear wheels, got the tires on hassle free first try. Got the headlight retaining screws in, look nice. Got word my hardware shipped yesterday and should be here by Saturday, but no word on the pipes yet, messaged the seller on eBay, and so far nothing...they were probably sent post is why it's taking so long.

Also Marbles Motors contacted me and said my airbox has like 6-7 cracks and it's going to tack on $50 for labor to fix them...that's great...But I guess it all evened out, got the wheels trued for $50 less than expected, and the bodywork is $50 more...at least it's not costing me more out of pocket right?

guitarkev66 · « **Reply #107 on:** September 06, 2012, 04:17:26 PM »

I just trued my wheels myself not too difficult and what a difference . I also just put a new set of k70's on them. Rides so smooth and I can take both hands off the bars @ 60 and decelerate without any wobble or head shake (that really impresses me).

dangerdan408 · « **Reply #108 on:** September 06, 2012, 07:13:50 PM »

Well, my eBay exhaust came in and I'm not exactly jumping for joy. One has acid stains a blind man could see, several dents in the header, etc. He said it had two dings and were only dirty...He didn't even include the header flanges that were pictured. I'm using one of my no numbers (the one thats not rusted) in place of the lower left hm300 I got today.

Awesome packaging

Put my guard on the outer right hm300

Hm300 (eBay) on right, no number on left

dangerdan408 · « **Reply #109 on:** September 06, 2012, 07:26:47 PM »

Message sent to dude, don't think I was too far out of line.

"Well I received the pipes today and I'm not exactly ecstatic about the condition, and the header clamps that are pictured multiple times in the listing were not included. The lower left muffler has extensive acid stains, numerous dents and dings throughout the set, notably some in the header pipes and lower muffler areas, the set is rust free, but not up to par with what the description provided. I would like to receive the header clamps at the very least for disparity between actual condition of the pipes and perceived condition as displayed and portrayed on the eBay listing.

Thanks,
Dan Boggs"

Thanks! I'm chipping away to get it done, now I just have to figure out what gasket set I need...and tensioners, etc...It never ends!

Interesting packing with the pipes for sure. Let us know what he says about the condition of the pipes. If this is the guy in Utah, looking at the pipes, he has another set already posted that look as yours do. Maybe he sent you the wrong pipes.

No reply as of yet, I know he's holding off saying anything until his other auctions go off...just goes to show 100% don't mean everything, of course the feedback system doesn't work if people don't speak up. I'll just keep them, I've got a line on another K0 so after I buy a set of no number yamiyas (when it rains $), these will go on the other if it pans out.

I got the plating back today, and overall, it looks good...a little too good really lol, it's BRIGHT. Only a few things damaged, my brake rod adjusting nut lost its threads, must have been mostly rust. For $100, I feel this went further than just about anything else I've done to the bike. Pics!

All in all your getting good results from the supplier side of things. Yes, its an interesting bike.......lots of early original parts but a few suspect items you have identified. Note the brace on your center-stand. I have a later # K0 without the brace so possibly yours was switched at some point. Your working much faster than most of us. Its great to see the next generation loving and working on OUR favorite bikes. We are watching with interest........

Thank you for your kind words...if younger guys like me don't step up and do our part to get involved wrenching, restoring and riding these old bikes, they're just going to end up as rusted heaps of the past in someone's garage. I really love the older bikes, I'm 27, and have been riding motorcycles 22 years now (dad put me on a bicycle when I was 4 1/2, got that then for my 5th b-day, a Yamaha PW50 lol)...they are my passion and hobby. I am beginning to be on the fence about this bike, the only things that have been changed are the handlebars for more touring capability over the K0 bars from the way it was sold new, I got the bike from the original owner and my uncle has known the guy longer than 30 years, and somehow I ended up with it. Other than a minor spill to the right, scratching up the chrome cover on that side, it was fairly undamaged. The stand is original, this is a weird bike and by my searching is an early 3/70 bike in the 26xxx frame and engine range with lots of weird early K0 parts...kind of a parts bin special to get rid of the left over early stuff.

And thank you for the working quickly compliment, I'm just trying to get this thing done right for barbers so I can cruise around in style.

Got a little more done, got the carbs back together and they look pretty nice IMHO, started getting the bike back together a little, not much, just more grappling area to lay the frame over the engine when I get through with it.

Thanks! It feels like an uphill battle most times that I work on it, but I think I'm making some progress now.

dangerdan408 · « **Reply #122 on:** September 10, 2012, 04:32:21 PM »

Got the all balls kit in, brand new in the box, $29 off amazon shipped. I did kind of mess up the races in the steering stock, so I beveled them back out with a rotary bit, and drove the all balls races in place. Feels pretty positive, I can already tell there won't be any clicking in the headstock or squirming of the front end under braking. I did manage to forget the trim ring/ nut that goes over the top race...it was rezinc'd and will go on later when I have some time.

Damage...

Beveled back...

Getting closer...

I think it's fully seated, it just doesn't look like it with than cover nut off...

Yeah, that looks like the bearings might not be fully seated. The triple tree will sit a bit higher with the tapered bearings but that doesn't look quite right to me. You left the cover nut off?

Tews19 · « **Reply #124 on:** September 10, 2012, 05:56:31 PM »

I think you did it backwards. On lower stem goes the thin washer. Then the rubber gasket. From the look of your pic the gasket on top on stem.

After gasket is then the lower bearing.
