Hell if I know, but they aren't anywhere to be found in the garage. Not like I wanted to have to re-buy them.

Haha, I hear ya! Lots of parts are floating around my garage, waiting to be found. I have a favorite bit set that dis- and re-appears regularly.

Congratulations on your promotion! You're at Norfolk Navy Yard? That was my Dad's first posting, in 1943. Your bike build is terrific -- looking forward to seeing pix of it on the road.

I am at VAW-120 which is on Norfolk Naval Station.

My bolts came in yesterday so today I put the case halves together (again). Everything went smoothly this time. Tomorrow I will lap the valves and assemble the head. I need to wait until payday to order some new piston rings and a flex hone. It is slowly but surely coming together.

Congratulations on the promotion Senior Chief Petty Officer! That's cool. Thanks for your 22 yrs of service!

The microfishe tells you bolt dimensions on most if you have a good fastener supply house. Just use some silver colored antisieze if you go with any stainless hardware in the aluminum alloy cases. Naturally, there is also the factor of adjusting torque values depending on if the threads are lubricated or not. Plus you have to be carefully on blind holes in the cases are clean and debris free. Some have learned the hard way with pooled lubricants being noncompressible in a blind hole or debris from glass or plastic beading. Some of the gotchas that can make things break.
Glad the case screw was an easy removal...just a pain to deal with.
Enjoy watching your build.
Btw, good looking family!

Today's challenge is to take all of these parts:

and get them assembled correctly here:

The problem is that the manual doesn't really show or state how and doesn't provide torque specs. So I am down to looking at pics on the here and a youtube video.

Turns out that it was a little easier than I thought it was going to be. The youtube video pretty much walked me through it.

Nice. Sometimes, the task looks more difficult than it really is. Sometimes...

Ughh...the not so complete gasket kit has struck again. For anyone who is watching I have the Cycle X complete gasket set and oil seal combo. Previously I discovered it did not contain the o-rings for the neutral stop and the main oil gallery. They both are the same part number 91307-KF0-003. So I ordered them from my local dealer.

Now I am going through the rest of the gaskets as I am preparing to put the jugs and head onto the case. So I start laying out all of the gaskets and notice that the gasket that goes between the jugs and head has the large holes in it. According to HSB #42 I should have 8 o-rings to make up for the larger holes. The serial number of my engine did not have the cut outs for the knock pins and knock pin seals. However the o-rings/seals included in the kit are for engines with the higher serial numbers that had the knock pins. Looking at the service bulletin I require the o-ring kit which is p/n 12115-300-305. After some research others have had success in acquiring them from Western Hills Honda. However, the last instance I can find of someone ordering them was in 2010. Hopefully they will have another set when I call tomorrow.

So I continue on with checking the Cycle X kit. Sure enough two more o-rings are not included. Take your pick as to which ones are missing since they are the same p/n. Either the two that go on the case on the back edge between cylinders 2 & 3 or basically in the same position on the top of the jugs. My kit only had 2 of the o-rings when there should have been 4. They are p/n 91310-426-000.

So in summation the Cycle X kit is missing at minimum 4 o-rings and depending on which engine you have up to 12 o-rings. Needless to say I am very frustrated right now.

That's frustrating as hell. I just ordered all those o'rings from Bike Bandit and from Western Hills a few weeks ago. Also for the dowel pins and thick o-rings if you use a Cometic gasket you can leave them out. That's what I did.

Well I just got off the phone with Western Hills. They still had some of the gaskets in stock. However, it appears that the cost has gone up from what others had posted. They are no longer $6.14 per set, but rather $20 plus $8 to ship. I guess I will go to my local dealership and order all of the other o-rings that I need.

I inquired as to why others have stated that they paid $6 and mine were $20. Partially to make sure they had the correct part, but also to see why they were charging me about 3.5 times as much as others. He said they only had a few kits left in stock and that the owner of the o-rings upped his price because of it.

My cylinder hone arrived today and I couldn't wait to get to it. For reference I bought the 2.5" 320 grit FlexHone. My piston rings also arrived today so I will be able to at least marry the jugs to the case while I wait on the rest of my o-rings to arrive.

Harsh · « **Reply #109 on:** July 19, 2012, 09:15:06 AM »

The pistons and jugs are on. At this point I am literally at a stopping point on the engine until the rest of my o-rings arrive.

Harsh · « **Reply #110 on:** July 19, 2012, 01:43:02 PM »

I was a bit surprised today. All of my o-rings came in. However, since it is the boys birthday today I won't be doing any work on the engine until tomorrow.

RAFster122s · « **Reply #111 on:** July 22, 2012, 08:08:55 PM »

Glad you made your sons birthday special.
Best on the coming reassembly....be sure to be careful on head reassembly and use rubberbands to prevent valve damage....lots of 550 owners learn the hard way...

Harsh · « **Reply #112 on:** July 22, 2012, 09:22:27 PM »

Can't believe I forgot to post this, but I got the engine basically back together. It wasn't easy. The gasket between the head and jugs did not fit correctly. When it was placed over the dowels it caused it to bubble up in the middle about a 1/2". So I had to take out the dremel and round out the hole a little so that it would fit correctly. I didn't put the tappet caps on because I still need to polish them. I will say that adjusting the valves was a pain in the rear. I followed the manual to the letter, but I couldn't get a feeler gauge in the #3 intake even with it fully loosened. The manual states that you can adjust #1 and #3 intakes and the #1 and #2 exhaust at the same time. So I had to deviate from the plan just a little and adjust each cylinder one at a time.

Head on and torqued

Camshaft and rockers installed

Valve and breather covers installed.

Well work has been kicking my butt lately which has prevented me from doing a whole lot of work on the bike. However, I was able to powder coat a few more pieces over the weekend. I did a few more, but they are small insignificant pieces. I also performed the clutch basket drilling mod, but since it is documented on the site pretty well I didn't see the need to take a lot of pics of it. I just took some pics for reference in case something went wrong during assembly.

Just a couple of pics of the powder coating I did. It is surprisingly easy to do, but I can see how you could very easily #$%* it up.

I did the blue grooves. The grey was done by the pro.

Looks nice! She's coming along nicely.
Did you coat the fin edges with anything after sanding them? Is it needed?
Motor looks very nice and shiny! It will tone down some when you get it in the frame and the rest of the bike around it.
Thought about the exhaust you are going to run yet?

PC results look nice...good job!
Biggest problem doing PC at home is an oven dedicated to it that is large enough for some of the parts. Whose PC gun setup did you go with? HF, Eastwood, etc.?

Harsh · « **Reply #116 on:** August 08, 2012, 12:00:53 PM »

I haven't coated the fin edges with anything. It has been a while since they were done and they still look the same. Now once it gets on the road it might be a different story, but maybe the wax in the polishing compound will protect it.

I want to run a 4-1 exhaust. Cost is the limiting factor. I am working on a deal so hopefully I can pick one of some what cheap.

I did the PC work at a buddies house. He has an oven in his garage dedicated to it. He has a cheapie HF gun, but it works.

Stev-o · « **Reply #117 on:** August 12, 2012, 05:15:26 PM »

Motor looks great. What's next?

Harsh · « **Reply #118 on:** August 13, 2012, 05:12:06 AM »

Lots of little things to do. I still have to source some SS spokes. I would rather not have to pay $200 for them from Buchanan's, but they are probably the best bet. Still need to buy wheel and neck bearings, fork seals, rebuild the carbs. The list could go on for days.

Look to these guys for spokes. This is who I got them from for my 550. Much cheaper than Buchannans and fit was perfect. Lacing sucks. Follow the thread thats on here, it took me two times to get it right, but worked out good in the end.

Harsh · « **Reply #120 on:** August 14, 2012, 06:38:56 AM »

Thanks for the link. I will look through and see if they have what I am looking for.

Harsh · « **Reply #121 on:** August 17, 2012, 02:02:05 PM »

Got my fork seals in today along with a few other parts. I need to replace the springs, but right now the old ones will work for what I need. Plus that is a 10 minute project which can be done later. For right now I can at least do some mock ups.
