The smaller signals I find much more aesthetic like yourself...  Do t always get to choose the year of the deal that drops into your lap. Glad you had the skills to backdate to the smaller signals...

Nice work!

Next 1976 year problem to be addressed is when I get to the bucket.  I need to wire in the earlier model headlight switch with the new smaller turn signals that only come on when activated.  I know these updated 1976 on modifications with the large signals and continuous headlight were for safety, but they are not winning any awards for looks.....

I have not got to the front of the bike yet, but as I stated, I will be using controls from a 74 model with a headlight switch and the continuous headlight and running lights via the turn signals will disappear. Anybody have an opinion as to the most feasible path to make this conversion,

A. Rewire the current 76 system which includes the first year of the diode.....I have done it before but the old memory is not what it used to be......

B. Use the entire harness from the 74 parts bike which is in great shape and has already had the safety switch bypass installed......

I am at point where either is accessible because the bucket will be coming off for paint shortly.  Never hurts to ask what would you do???????????

Are you intending to have front marker lights on the bike lit when running or revert to the early front turn signal assemblies be dark except when operating as turn signals. I'm confused about the safety switch comment.  Not being familiar with the 76 750 adds to that...
The front signal assemblies with early signal size are not wired for marker lights and only feature a single wire to the bulb socket. So, the only easy way to add marker lights in front with early signal bodies is to use rear signal bodies in front to give you that capability.

If you don't want the front marker lights then your 74 wiring harness is the fastest method getting there and sounds like ideal choice of the 76 switched to having always on markers front and rear and always on headlight. If you want front markers with small 74 (and earlier) turn lamps then installing the rear turn signal housings then you can put a small auto relay connected to your turn signal switch to be switched to kill power when the turn signal switch leaves the center off position to either right or left turn the switch so powering a NC relay contact for markers and when moved to right or left that now deactivates the relay. So when the turn signal flasher has power the marker lights do not. The wiring for your turn signals taking over for that turn signal filament.

But, it sounds like you want the early switch and early turn signals and early non-fr9nt marker setup.
I would take the easy path and use the 74 harness.
Why make life hard when you have an easy solution available?

PAINT......Finished up three coats of clear this morning on the tank.  Overall I am not happy with this one.  My decals were off slightly on placement, the paint from across the pond I felt was a little light in consistency and the nozzle resulted in several drop spots.  I received a ton of base coat in the aerosol can but the candy I felt was not as full.  With all of that I ended up with a few arears I am just not happy with.  I lightly sanded the paint with 2000 grit prior to applying the decals because they were so large and to bring down the paint lines between the two colors, that was probably a mistake on my part.  Regardless, it is too damn expensive to think about a re-do so I am living with it.   The side covers were a piece of cake, I just roughed them up with 1500 grit and reshot the clear, they really did come out better than expected.   Considering what it looked like when first arriving, I guess I should be happy for the improvement. Each one is a learning experience......

Looks good in photos and it is you who will see more wrong than others as you know where any mistake might lie. Others are likely to never know unless they spend hours washing and waxing the bike...

Moved to the front this morning, forks are pulled and the rusty tops treated with good old Naval Jelly.  I was surprised when I drained the fork oil, looked almost brand new.  I am going to have to go through my collection of extra fork ears, these are pretty rough.  I thought I was finished ordering parts, brake pads are down to nothing.  I am also enclosing a shot of my new fork tube driver, it is a 3/8th extension with a garden hose cap on the end, even with my invention the removal process reduced my dead blow hammer down to its final days.  I called it quits at noon, temperature is hanging right at 100 degrees with an index of 104. hard to work when you can't see out of your glasses for the sweat.  Of course you spend half of you time moving bikes around to give you room to work, what I would give for a bigger air conditioned garage.......

Britman…… A month ago I spent an afternoon doing this (see photo). Troll KIJIJI and just do it. Smartest couple of hours I ever spent. Small shop = even better!

Looks pretty good for a home job in the photos. I'm glad to see you painted the side cover tab black. It's an important detail often missed.

I cannot take credit for that, it was painted before I cleared the covers.  That is a fact I never knew, add that to the "learn something new everyday" file......

Yep, I can still do it.  Pinched a tube today mounting the new front tire.  It had been a long while since I murdered a perfectly good inner tube, guess I had to prove I still had the ability.  The front wheel is from the old chopper parts bike and I was truly impressed at the condition once I removed the grime.  New seals in the forks and the bases somewhat polished.  I also cleaned up the exhaust hardware since I am going to install the spigots and new gaskets while there is good accessibility with no fork tubes.  Front end starts to go back together in the next couple of days, final wiring, and hopefully I will hear it run again within the next week or two.  I have a lot of parts scattered around on this one, hope I can find them all when their time comes.  I would like to wrap this one up as soon as possible, unfortunately the organ in the body of old men like me, "Mr. Prostrate" is starting to cause some issues.   If you really want a good time, go in for a biopsy down there, that damn sure will get your attention. A final word of wisdom for the younger members here, "Gentlemen, never ever underestimate the feeling of a good pee".........

For all intensive purposes, the cosmetics are finished.  Took it out for about a 10mile run this afternoon and the bike runs perfect.  I had forgotten how throaty the OEM pipes are without the crappy baffles.  I am still going to throw some clutch discs in it before listing it for sale.  It is not slipping but you can tell it doesn't have a lot left.  Overall, very pleased with the final product......

Nice.
So are they 341 pipes or 300 type baffles?

So you just removed the end caps? Baffles are welded inside the mufflers on the 341s.

That bike looks fantastic. I take 4 years and you do them in less than 4 months. I am impressed to death. Don’t give this one away. This summer taught me you just have to wait for the right person, that’s tired of looking at junk….. Well done!

 Thanks John. much appreciated.   Looking at K's on the market currently, the price appears to be down somewhat, but I agree about not giving it away.  It is a lot of work and the project bikes are really getting harder to find at the right price. 

Newday, thanks for the clarification on the pipes, there were no end caps when I bought them.  Even with the baffles, they still sound good.....

They're the early 'no number' pipes ?

I went back and read through this project just now, and they are 341s, that he bought with no end caps on page 1. He had miss worded saying there were no baffles, he was thinking the end caps were baffles, which is why I asked. Yes I make mistakes in words too.

Brittman it looks good, it's come a long way from the zebra frame and corrosion caked bike it was.

As a help, not a critique, you might want to swap sides of the passenger pegs so they look right. They should point up toward the rear in  the correct position. That is so your legs(the rider) don't get jammed if the pegs are down and your leg hits the pegs, the pegs will swing up when hit, not tearing pants or flesh.....
This bike belongs Andy750 to show you how the pegs should look. The back of the bracket has a notch that corresponds to the muffler notch so the bracket kinda locks in position before tightening the nut. IIRC, the brackets are marked L and R.
