Today I figured out why the LED lamps in my rear turn signals cross talk!

Honda saved a few yen by using on unusual circuit on the dash board turn signal indicator lamp.  Just attached the RH & LH hot connections to each side of the indicator bulb, knowing the lamp would ground thru the filament of the non flashing turn signal lamp.   :) :o

Remove the bulb and the turn signals with LED's and a  electronic relay work just fine.

Ha, now I just need to set up a separate circuit to flash the bulb; Air Force B.E.T.  paying dividends.   

Ordered a new dashboard harness fro Z1 enterprises, and some LED indicator lamps from evilbay.

Might as well go in whole hog!

Oh and I filed my taxes... ::) :(

Did "The Works" tank treatment in the morning.  Filled her to the neck and road about 70 miles in the afternoon.  This 'new to me' 550 runs really nice.  But, man if I run her at 4K revs and over, I feel like the swiss cheese HM323's are going to rattle apart.  Absolutely love the look of the original 4-4's, but I might have to install my 4-1 sooner than planned.  I hear these 550's love to be revved, but I haven't even hit 5K on the tach yet.  Am I missing out?  Also, I checked mileage and I ran 36 with most of the miles at 65 (3,500 rpm in 5th) on the highway.  How normal is this?  (550K2)

Anyways, here are a couple before and after picks of "The Works."

Good job cleaning the tank.   You should get 45 to 50 mpg and the bike should rev way higher than 5k.  Check the air filter box for obstructions or a dirty filter...Larry

Larry, it will rev over 5k, but I haven't had it that high on the road due to the rusted out exhaust. Next, I plan on checking timing, tappets, points, air etc to see if I can squeeze another 10 mpg out of her. I appreciate the input! Nice to know I should be getting better mileage. It was seriously windy too, so that probably played a role. - Kyle

No, I wanted to use something that would work a little quicker, so I used "the works" toilet bowl cleaner method. This method is posted everywhere, but these were my steps:

1) removed petcock, poured old gas out, & dried up tank with compressed air.
2) plugged holes with rubber stoppers from HD
3) poured in 3 bottles of "the works"
4)  shook tank every 5 minutes resting it on different sides for about a half hour.
5) got cleaner out and quickly neutralized with baking soda/water mix
6) ran warm water through the tank pouring out both petcock & filler holes for about 5 minutes
7) poured water out as quickly as possible then poured a can of denatured alcohol in, swished around for a few minutes to soak up moisture.
8 ) dumped out alcohol and blasted tank with compressed air.
9) once completely dry, I fogged with wd40, then sloshed some gas around. Dumped out gas and poured in another bit of gas and sloshed around... Dumped. (This step was probably unnecessary)
10) installed petcock, filled to the neck with 91 octane & a shot of seafoam and went riding.

Whole process only took about an hour. No pinholes... everybody is happy!

I'm amazed by your collection! How long did it take you to build up something like that?

Finally started my K3 today, first time on new rebuild. It's a ported 836 motor, with a Carpy"Yoshi" exhaust, and a mild megacycle cam. Sounds really good, and seems to run fine. Was nervous starting it for first time, as this is my 1st motorcycle engine rebuild, but all appears to be working properly. Couldn't have done it without this forum.

Finally got everything all buttoned up!
 
The blank canvas...


Permatex FormAGasket 2 goes in the recesses, then the 0.030" shims.


Then the pucks had a bit more Permatex put on their edges, and sat down into the recesses. Pressed them down as much as I could to force out any excess, then cleaned up.


Cam towers in place, before timing the cam... Thanks again, Rafi! Definitely the best way to get the cam chain, sprocket, and shaft in place can be seen in Dean's video...


Put the bearing caps on after timing the cam. Oil goes into those little recessed holes as you put it together! At this point, after releasing the cam chain tensioner, I decided to use the kickstarter to make sure I had oil coming up to the top end. YEP! Sure do! Took about 30-40 kicks to see it spurt out of those little holes. Having the spark plugs out really helped!



Everything all in place now, before setting valve clearances. I left out the 5mm rocker shaft retaining bolts, as recommended by HondaMan. I did go through and check to make sure each shaft's oil groove was visible with side to side motion of the shaft when the bolts are in place. Only one had to be widened, thankfully... #2 EX.


Valve clearances were set according to the book. 0.002-0.003 for intake, and 0.003-0.004 for exhaust. Setting valves, for those who have never done it before (LIKE ME!) is pretty straight forward. What I did was go for the smaller of the two numbers. Tighten the adjuster down LIGHTLY onto the smaller feeler gauge. It should slide in that space with some friction, but not stick. Tighten the locking nut. Check once again... the smaller one used to set the spacing should slide back in with some friction, but the larger should not go at all (or maybe with a good pull through).


After a restless night...


Upon putting the valve cover on, I forgot that I had not replaced these two screws, and they were all stripped. I managed to get them to approximately (by feel) 90 in-lbs using vise grips. Going to get some socket head M6x80mm bolts on Monday and take that breather cover off again.


And here it is, all buttoned up. Frame section put back in, too. I'm going to swap the front two frame clamps so the bolts are facing out on the bottom, rather than angled like this because of the coils.



Everything went back together after this... carbs, airbox, etc... She fired right up! No problemo! I'll post more pics, obviously, once I get those other screws replaced in the breather box. Thankfully not much has to come back apart to do those screws. It was nice to hear Rhonda sing again!


Got those two screws replaced...

Before:


After (M6x80mm 12.9 grade steel socket head):



Then I put it all back together! She starts, but it is on high grade gas and too much MMO in the tank. Going to go get some more fuel tonight, and then properly dial in the air screws. Things seem a bit rich!




 Things I noticed, putting the carbs on and off for what seems like the 100th time...

1. Lubricate the rubber with something. I used saliva. Cheap, and always available.
2. The airbox rubbers seem to have a long side and a short side of what sticks out of the box. Have the LONG side on top. Now, when you rock the airbox upper half upwards to install the boots, the rubber will go right to the carb body on the top AND the bottom.
3. Make sure the carb bowls are level with the engine case (use the starter motor cover as a guide). This can be accomplished by rotating the rubber boots AWAY from the center to bring the bowls DOWN. Turn TO the middle to bring them UP. Having them level makes installing the airbox boots and holding bolts much easier, too, as you don't have to fight to push the airbox top downwards.

Fixed that which was not broken. 

Starter motor in my GL1100 that is.  It cranked OK, but I knew she could do better.  Bought new brushes, but the ones inside have plenty of life so didn't change them.  Cleaned out the carbon and the old grease and shined up the armature.  Lubed 'er up and reinstalled.  Cranks a lot faster now!

Rode the Plastic Fantastic Scooter on Steroids, aka Red Maggot, aka THE GOLF CART, aka a Honda Pacific Coast.   First Honda that has ever left me stranded, well almost.............the battery that I had just replaced two weeks ago went dead.  I was 20 miles or so from home but was fortunate to have a kind stranger help me bump start the red load.  Got home, checked charging(which I neglected to do after replacing the old, worn out battery :-[ :-[)  and found the rectumfinder to be defective. So I went inside and ordered one then walked back to the shed and lo and behold there is the rectifier I need sitting on the top frame of a basket case 2000 CB250 Nighthawk I bought because it had a 400 four tank on it.  Installed the rectumfinder and back on the road.  Probably keep the one I ordered for a spare...Larry
