So you mean the original ones the painter lost were the ones he gave you in the first place?

Very Funny!!!.............Gary

Ding, Ding, Ding.........We have a winner !!! 1st place prize are some of Johnie`s prize Peyote Buttons. lol Seriously There is a welded nut on the backside of the ears that is definitely factory also on the LT ear there is a bracket on the inside of the ear. I`ve included some photos that may help clear this up. So I`m guessing the K0 ear and the K1 ear are identical ? Thanks for your help guys and Johnie I appreciate your humor.....Gary

Good eye Chef... Not sure for sure but on my 550's I have had, that is where the turn signal buzzer attaches to...

Possibly for a 550 those ears? On either of my K1 bikes, I do not have those.

Stev-o · « **Reply #131 on:** January 06, 2013, 02:17:15 PM »

Yes, tab is for the turn signal buzzer, have one on my K4's ears.

Tews19 · « **Reply #132 on:** January 06, 2013, 02:27:26 PM »

Now you know for sure they werent from a K0-K1....

cheftuskey121 · « **Reply #133 on:** January 06, 2013, 03:31:25 PM »

well crap....now I have the wrong ears. they seemed to fit on the bike fine, and I took them off. should I just leave things be if they fit fine? Im not going for 100% restoration. I guess if it ain't broke...

Geez, I nearly pulled the trigger on that first one until I remembered that I already have a good pair, ha ha! Cheers, Terry.

Pretty sure they are the same as my K4 ears.

I think that means they probably fit K2-K6.

There seems to be an abundance of right k0-k1 fork ears on ebay but not left. Reason unknown.

Garystratos201 · « **Reply #138 on:** January 07, 2013, 07:09:53 AM »

Mystery solved. After looking through ebay I finally found a set that matched what I have. The one I found on ebay is off a 1974 K4 which was a chrome set. I called my painter this morning and told him I had done my home work and these ears were not for my bike. He honestly thought his fathers was a 1969 or 1970 cb 750. I had to break his heart and tell him that the fork ears off those models were painted and not chrome. I`ve known this guy for a longtime and know he`s honest . He tells me he will get me the correct ones. Here`s crossing my fingers. Thanks to all ya`ll for your help.

Now the only mystery left is what year carries the 8.5 inch steering stem. Anyone have a clue ?...................Gary

Gary I had an issue with a lower triple tree for my silver K1... it wouldn't seat properly... Took me a week and borrowing a micrometer to find out the reason it seemed shorter was the fact it was wider then the proper K1 stem.... Let me look up the thread I made about it...

FOUND IT>>>>> EDIT

Thats not the problem Tews I measured the stem from the bearing seat to the top and one is 9.5 the other is 8.5. I ordered another lower tapered bearing and seal today so I`ll just use the one I took off of it. I would like to know what it fits so I could sell the old top tree and the stem. Money to be toward my project...........Gary

Yes you did Terry but me being as hard headed as I am I had to find one that matched the square hole bracket on the left ear before I was convinced. So technically you did solve it and I stand corrected my friend. Now how about that steering stem?...........Gary

Tews19 · « **Reply #143 on:** January 07, 2013, 01:16:13 PM »

Not sure if this helps but this is from my gold K1. I had to find a new one since the bottom tab was bent. I could have had it welded but I didn't. For sure it is original to the bike. It measures approx. 9.25 inches long. Also where the threads are is different from the other lower stem I have laying around.

Tews19 · « **Reply #144 on:** January 07, 2013, 01:17:15 PM »

Gary if you want. I can send it to you free of charge. You will need to weld the lower tab or leave as. Just pay S&H

Garystratos201 · « **Reply #145 on:** January 07, 2013, 01:43:44 PM »

Thanks Nick I appreciate the offer but I have the one that was in the bike when I got it but it wasnt a unicorn and I bought the unicorn set set from a forum member. The set I bought has the 8.5 inch stem.

Stev-o · « **Reply #146 on:** January 07, 2013, 06:02:49 PM »

Your painter may not be lying. Unless you bought the bike new, do you ever really know if every part is truly original?

Very true Stevo I asked him to get me the frame number and I would cross check it from a conversion chart I downloaded. So far nobody has had an answer about the steering stem. I would like to list it for sale but I`m not sure what to list it as...Gary

Garystratos201 · « **Reply #148 on:** January 16, 2013, 06:27:09 AM »

Off the work bench and on the ground. With the help of my son finally put it back on the floor for assembly. After the struggle with the fork ears I decided to use what i had until i could find another affordable set of proper K1 ears. Prepped, primed with a self etching primer and painted the lower stem a semi gloss black. The All Balls tapered bearing kit already had been installed. All in all a fairly simple process. Also trial mounted the coils after clean up of terminals. Anyone know if the routing of the spark plug wires are correct.. Tomorrow I will start the refurbishing of the wiring harness and get it installed. Wish me luck !!!...........Gary

Garystratos201 · « **Reply #149 on:** January 17, 2013, 03:05:57 PM »

Well I installed my wiring harness after refreshing some of the wiring sleeves that had hardened over the years. Put in a new battery turn her on and nothing .........I mean absolutely nothing happening. After pulling down several exploded views of individual wiring circuits from Hondaman ( what would we do without him) I finally tracked down the problem. The ignition switch is corroded. I could wiggle the key and make it work .I had power to everything but after working with it all afternoon it eventually stopped working. So now I`m in the market for a ignition switch. Oh well the never ending build continues. lol................Gary

ps; I`ll post images tomorrow I`m too aggravated right now.
