Not yet, will try tomorrow evening I think. A friend wants to come for the official start up. I'll report in as soon as I know how it's running.
Cheers,
Cliff.

Not quite ready it seems. Put the portable gas tank to it and 3 of the 4 carbs leaked from the overflows. Had the replace a couple of needles, re-cleaned the seats, reset two of the floats and she seems to be holding tight. It turns over nicely. Tomorrow evening for some noise.

Good luck! Anxiously waiting a report.

It's ALIVE!!!

Fired right up and once I got the idle screws adjusted settled into a nice idle. And shifted through the gears. Peaked into the valves and oil flowing too. Yahoo!
It's ALIVE!

Alright Cliffy...sounds great even with the air box off there. Very nice...sort of takes the apprehension away now that you know she runs. Nice..........

One more, yes I'm excited! "Smoke" from exhaust because it's cold here in Paradise. Cliff.

Just to keep track of my posts elsewhere about this project, this one about the oil gallery under the shifter cover. http://forums.sohc4.net/index.php?topic=99721.msg1112960#msg1112960 Cliff.

Magpie · « **Reply #307 on:** December 19, 2011, 11:27:10 am »

So, it appears there is not a plug at the end of the oil gallery under the shifter cover but there is one on later models. All the engines I have worked on have been apart before I got to them so I didn't know if a plug was lost before or if I lost it. Now we all know about the plugs.
I got a new gasket, used Hondaman's suggestion to use some sealant on it so I used Permatex Grey, the same stuff I used to seal the cases, and it's dry now. The purists will go after me for this but a Honda leaking oil is forbidden.
Now the leaks at the edge of the head. A Honda mechanic friend of mine said it's because the head gasket is not crushed enough there. The head stud nuts were all torqued to about 14.5 foot pounds. On a previous build I had to use double washers under the stud nuts to get then to torque down. It seems the nuts were running out of threads on the studs. So, out comes the motor. Should be a long afternoon job.
Cheers,
Cliff.

progress is painfully slow here. I got a good buy on 4 pistons, starter and clutch cover in nice chrome this week. So, as soon as the pistons arrive I can send the cylinders out for reboring to .25 over. This motor was badly seized and there are marks in the bores. The mechanics where I shop say it would be better to start with fresh bores.
Meanwhile I've rebuilt the master cylinder. I'm not sure if I should paint it because it's a bit scruffy but it still has the red inspection dot on it from the factory. Most of the pictures I've seen of early K0's have a silver or slightly polished cap on the cylinder so I'll go that way.
A few pics.

Wouldn't that be .025 thousandths over, not .250=1/4 inch!

lucky · « **Reply #309 on:** December 19, 2011, 02:40:30 pm »

It is looking very nice!!
Good work!

About those carbs....You need to go buy four new float needles and then re adjust the floats for the new needles and then never readjust those floats again. Just replace the needles if the floats overflow. You do NOT need the seats with rubber tipped needles, the needles only.

Did you take out the slow jets(idle) jets and make sure you could see daylight through them? If not you WILL have to do that.

Cliff, correct me if I'm wrong but that is .25mm, the first oversize.

My guess would be .25mm (about .040in).

You're right of course Mark, Lucky and Bob! And if it keeps peeing gas new needles will be ordered quickly! I went through the carbs carefully and the idle jets were soaked, cleaned and cleaned again. It idles quite nicely. Thanks for the tip Lucky. You went back a long way in this thread Lucky. Cliff.

Merry Christmas........Nice Avitar for New Years!

Thanks Old Scrambler! I see you're a Bonnevile salt flats record holder. I had the pleasure to meet Tom Miller at a friend's house not too long ago. Nice quiet man that goes very fast on a streamlined Trident. It's a small world out there, you probably know him.
Cheers,
Cliff.

Old Scrambler · « **Reply #315 on:** December 19, 2011, 06:34:19 pm »

Tom is indeed a quiet man...........that goes REAL fast on old metal. Yes, I actually helped him change the jets in his carbs in 2009 when I had nothing better to do than offer to help. It was meeting him and others on the Salt that got me thinking about building something to compete............Just happened to have a pile of Triumph Cub parts laying around. If you interested, take a look at

I'll have to check my bottle inventory..............I think I can match you on the Eve!

Magpie · « **Reply #316 on:** December 19, 2011, 09:22:30 pm »

I'll have a good look at your Facebook page, it looks real interesting. My bottle inventory will have to increase for the Eve I think.

Cheers,
Cliff.

Almost forgot, I realized that i didn't oil the fibre plates in the clutch so that was the job for tonight. Younger son coming in from Japan for Christmas http://jason-halayko.smugmug.com/ and he wants to hear the K0 run. I'll get that done and then take the motor out to re-torque the head nuts. Sounds like a rock and roll band The Head Nuts or the title of a very bad movie.
Pleasant surprise in finding some heavier springs in the clutch. The clutch lever is harder to pull in than my others and I thought there was a problem until I saw the size of the springs. Bonus.

ekpent · « **Reply #317 on:** December 21, 2011, 10:03:09 am »

Just for fun,you should compare those clutch springs if you think they are not stock, to the inner valve springs off a head. Seems like 'back in the day' that was a mod used on clutches

Think I have a few floating around if you needed some measurements etc.Know I don't have to tell you but if those springs are stronger be careful with that cover plate when tightening. Eric

Johnie · « **Reply #318 on:** December 21, 2011, 11:09:50 am »

Yah, take heed to what Eric says there Cliff. You do not want to break off an ear on the clutch plate. You need to really take your time tightening those 4 bolts ever so slow with a little bit to each bolt and work your way around trying to keep the pressure steady on all 4 bolts. Good luck with it and let us know how you come out.

Agree. I broke mine last time I did it.

Magpie · « **Reply #320 on:** December 21, 2011, 03:55:40 pm »

Yes, I have broken a clutch plate and the top plate in the past.

The springs are the same height just thicker. I tighten just a couple turns at a time, stating at 12:00 then 6 then 3 then 9 and repeat until they're tight. The other trick is making sure the clutch inner basket mates to the plate properly. That's how I broke the clutch plate peg.

Magpie · « **Reply #321 on:** January 02, 2012, 08:45:57 am »

Well, a step forward and one back. I pulled the motor to retorque the head because of the oil "weep" and decided to pull the head as well while I had the motor out. What a surprise! There was oil all over the head surface, the tops of the barrels, on the pistons and the gasket was soaked. Interesting. It was torqued to 14.5 ft. lbs. So the oil is forcing it way between the head and the barrels. The packings are new. I unfortunately went a bit cheap on the gasket kit (you can kick my ass if you ever see me) and that may be the problem. I spoke to the local motorcycle whisperer and that's his opinion. The head gasket I used is about 1.17 mm thick and the one I found in my inventory is about 1.47 mm thick and more robust. The new one is installed and torqued down. The wisperer and someone on this forum suggested letting it settle in overnight then retorque it. So that's what I'll do and then reassemble and install the motor. Hopefully that's the solution.
Dammit!

and

Cliff.

Prospect · « **Reply #322 on:** January 02, 2012, 09:18:01 am »

I'm not sure which gasket you chose but Vesrah (Japanese) seems to be the top choice. According to my local bike shop there is a 6-8 month back-order on them (I'm assuming because of the tsunami) and I bought an Athena set. I bought one of those 836 kits on ebay that's so popular on this site and they come with their own head gasket gasket so we'll see. The rest will be Athena.

Magpie · « **Reply #323 on:** January 02, 2012, 09:20:03 am »

I think I used Athena on my other bikes with no problems yet. Should have learned from them. Cliff.

Cliff, sorry for the set back but I just have to say how beautiful it looks in the videos.
Just dazzling!
BTW, your son has some amazing photos on his site.
Really like the fish eye lens effect.
