Thanks Cal

By the way, that M8 flange head nut is a head stud nut (in case you didn't realize it). Best to check under each of your pucks to be certain all yours are installed and in place.

I dont recall if you removed/replaced your studs. If not, they are already stretched, but the gasket compression is still needed with the re-torque. (As a point of clarification).

Cal I checked them already and oiled as suggested in the manual.

Cal well after I'd replaced the rubber puck gaskets with high temp gasket goo and decided to ask the question, I then thought I'm going to have to remove them and clean them! As I bet there'll be a way to do this and it's not the way I've done it!

Cal I've done what you recommended (sorry Bryan).

I've loosened them off in the correct sequence and retensioned them to 7 ft lbs or in my case with the mini tension wrench 84 in lbs after I did the conversion.

Question: Do I loosen them off again and then tension to 12# or do I just tension them from the 7# to 12#?

When I pulled off the old inspection caps they were all rough and scratched from the removal

I decided to get new caps, chrome. Not my preferred (was black), but the only black anodised were Joker which I didn't like and were far too expensive.

I've resprayed the rocker cover as it was getting greasy marks on it due to my on and off again process, I now look at the engine and it's had my greasy hands over it during assembly and looks a bit dull.

I'm thinking I might pull the engine out and give it a wash with wax and grease remover and respray it.

Any comments?

Repainting the gauges as I wasn't really happy with them, I blame SohRon for this reviewing and redoing.

I'm worried about the lean on the side stand, this one is 20 cms long. I sold one that was longer, is this too short?

calj737 · « **Reply #881 on:** October 24, 2015, 03:25:33 AM »

when you torque, you go in stages without undoing the prior torque. Tighten to step 1, then continue to tighten to step 2, then achieve full torque at step 3. Only ever release tension when you intend to undo, and also undo by cracking the torque in sequence before removing the nut fully.

Many unwind the nuts fully in reverse and discover later a warped head (not as common on these little bikes, but certainly quite common on V8s).

Not sure what the length is on my kick-stand but it's got way more lean than my 750 does.

Bike is looking good!

To head torque Honda don't even recommend a retorque at all and deffinately not a loosen and torque, In all the years i have ben doing them I have never had a gasket go

70s knowledge versus today's knowledge. I personally would go with Cal's and the list's wisdom.

MickB · « **Reply #885 on:** October 24, 2015, 03:14:57 PM »

Thanks boys for all the collective wisdom with these old bikes, I'd be lost without it.

The gauges had orange peel look and so more sanding and respray, SohRon and many others have set a high standard.

While waiting for the tank and side covers to return, I've got to put crush washers on the bottom of forks, refill with ATF, bleed front brake, finish the head torque, redo tappets and timing.

All little jobs but doable in time for the tank.

RAFster122s · « **Reply #886 on:** October 24, 2015, 03:49:55 PM »

Your orange peel could be because of high humidity or insufficient paint - if the distance from the spray can was correct.
Some can nozzles have a little better tolerance on the range from the object than others. As long as you are flattening the paint with some color sanding to prep for respray, then your orange peel should be reduced greatly if there isn't an issue...

That first coat of paint sure shows you anything you missed in body work...
gloss acts like a big magnifying glass saying look at me, look at me...

Good luck Mick!

You aren't the only one lost without the wisdom from this place... x2

Thanks Raf, it took a week but with lots of sanding and respraying I got there, major hassles getting the lacquer right. I think the nozzle (Rustoleum) was dodgy, it didn't take much to put it on too heavy and get runs.

Fixed the leak in the forks with new copper crush washers, refill with ATF.

I repainted the rocker cover and now have to redo the tappets.

Had lots of tropical rain which has slowed the paint job.

I'm not suggesting bryanj's method won't work, but offering different advice I've received from engine builders on all my motors. And using it, I've never had a leak or snapped stud. (Knock wood).

+1
We did this on Stella and (*knocks on wood, too*), we haven't had a leak on her.

Looking good Mick! Glad she's turning out to make you happy!
SohRon and now Folsoe have turned out beautiful examples of stock CB550 and CB500 respectively. SohRon of course has a fantastic documentation of his rebuild. I think he is considering selling a more in-depth version with different format ad more in-depth version for some areas thr thread did not dig as deep.
It will be a great resource for us 550 owners.

New chrome tappet covers arrived today

Finish tappet gaps.

Painter called me today and wanted me to come and look and to talk about the metal flake application, was I happy with the look? Base was a red pearl mica paint with flake over the base, still to apply candy. Covers looking great.

MickB · « **Reply #891 on:** November 06, 2015, 09:24:50 PM »

Tappets done, torrential rain for days now, so still waiting on tank & side covers paint job.

MickB · « **Reply #892 on:** November 12, 2015, 08:46:31 PM »

Still sub tropical rain daily which is holding the paint up, now 3 weeks at the painter.
Here's a progress photo

Black on the sides goes on tomorrow if the rain holds off, then 3 or 4 coats of 2 pack clear. Base of tank was done with POR15 and it'll also get a few coats

calj737 · « **Reply #893 on:** November 13, 2015, 03:55:09 AM »

Looks great. A couple of things though, Mick. The top edge of the filler neck needs to be bare metal. If not, vapors will infiltrate beneath the paint and bubble it off pronto. Also, the latch tabs can't take too much paint/clear else your cap won't fit and you'll be sanding it off.

Before the painter shoots the clear, have him clean the edge, then tape off the full radius and hold his clear below the tape. Then your paint will last a very long time

Thanks Cal I've passed it onto the painter

Stev-o · « **Reply #895 on:** November 13, 2015, 06:57:28 AM »

Nice paint Mick. What color is that?

MickB · « **Reply #896 on:** November 13, 2015, 06:42:28 PM »

The paint was removed from the neck of the opening, painter was slightly miffed at your comments Cal, but he obviously took the paint off. To give him credit the mouth was taped up originally

Just back from the painter. Here it is with the stripes on it, still pouring with rain, so no painting today again!

MickB · « **Reply #897 on:** November 13, 2015, 06:43:40 PM »

Stevo it's Candy Apple Red.

calj737 · « **Reply #898 on:** November 14, 2015, 04:04:21 AM »

Sorry he was miffed, it was to protect his beautiful work. Please pass that along- And he's not the first pro to make that error.

MickB · « **Reply #899 on:** November 16, 2015, 12:46:28 AM »

I'm glad he was given a bit of a tickle up.

Sun came out today. Black is on!

A light sparkle has gone on also, will show when in the sun.
