I built an aluminum plate, had it welded on, smoothed it out, and painted it. However I removed the entire neck for the pump, only retaining the tach drive part. Looks like it was that way from the factory

Oh nice! That sounds like a good solution, do you have any pictures by chance?

I don't do pictures, but there are several pictures around the site, that might have a good angle. It was bike of the year in 2009. Maybe someone can find you one

I just cut off the pump bracket parts and made the bottom good with the the two-part epoxy stuff, that comes like a sausage which you slice off and knead between your fingers.

Good news for me!! I found a Dyna ignition on the '79 and dyna coils on the '75!! I'll have to see what specific coils they are (proper resistance), so fingers crossed!

I posted a picture of the two different fork braces I have. The bolt-on is installed on the 79 and the hoop-style is on the '76. Are all these interchangeable? i know the forks were slightly different on the '79's, but I thought it was just the brake caliper mounts? Can someone let me know if the fork braces are interchangeable?

Finally, I posted a picture of what a lot of the seals look like on the '75 motor... It seems I'll have to be replacing most seals. This could be the lowest mileage motor (35k indicated, but it could be 135k+!!), so i think it's the best candidate for use vs. the '76 motor... Thoughts??

That Dyna looks waaaaay out of spec. All of mine have it so the gap between the modules is pretty close to the little notches at 12:00 on the case. Maybe someone timed them at T instead of F???
Whatever I suggest here should be given ample time for a moderator to delicately correct. I apologize in advance.

maybe! I'm not concerned with how it's set up on that motor, as it's on the untitled 79 and I'm keeping the '75, so I'll do some diagnostics (hopefully there are some) and make sure it still works before installing.

Anyone have a good method for removing the "tank" key? The PO had screwed it up, and there was no key, and I really need to get the tank open to start disassembly. Thanks.

So the '75 is a little rougher than I first thought. RTV instead of gaskets/seals on some areas, old fuel leaking from the pump, kickstarer won't turn the motor over (although it does spin) and the back lower portion of the motor seems to be covered in more oil than I'd like to see for now. The '76 is a LOT cleaner and everything looks much newer. The odometer has a black face and the tach has a green one, making me think the speedo was swapped on at some point and therefore I have no clue what the mileage is. The '75 shows 35k, but judging from the looks of it, I wouldn't be surprised if it's rolled over once or twice. Oh and get this!! The lower portion of a soda can for the points cover!!! He literally built the lower mounting boss from an epoxy/RTV combination and screwed that on. I'll get pics soon, unreal!

But on the good side, the '75 does have Dyna coils, a tube fork brace, K&N filter and a gutted exhaust. My fingers are crossed that the carbs just might have been tuned properly to allow proper running. If not, stock air filter and my 4-4 pipes will go on, along with the Dyna S from the '79.

Looks like I still have a long ways to go before getting a runner. I'd LOVE to have the '75, but from just the looks of it, the '76 seems the most likely candidate. I'd hate to do all the work of swapping motors just to have the '75 on the road.

What does everyone think?? Were there any engine differences between the '75 and '76? Will the value be higher for swapping motors or even be worth it to fix the issues on the '75?? My gut is telling me the value and performance differences are negligible, if any... Thanks for the help everyone.

The 75 & 76 were identical specs. No difference in performance between them.
Simply swapping engines is a days graft; lift the carbs, drop the exhaust, 2 long bolts, 6 short bolts, 2 rad hoses, fuel line to pump, circlip on drive shaft, points lead, starter lead.
There, that didn't take long, did it? :-D
A 79 engine has some improvements in that the crankcases are stronger and the gear train beefed up, but the performance suffered some from the cams, carbs and ignition changes.
But you have all the parts to swap over the earlier stuff to the late engine (just in case you found yourself with nothing to do one day :lol: )

I see, so put the best of the '75/'76 in the '79 engine huh (cams, carbs and ignition)? I don't really see how that would be worth the time?? But certainly a great way to kill some time!!

Since I'll be using a randakk spin on conversion kit, an Amsoil EA15K51 filter replaces the WIX 51348 that Randakk recommends. The Amsoil is likely to be better quality and should filter things out better. This is mainly for my own records so I remember when I get these parts set up.

Amsoil makes good parts but Wix is pretty high quality too. And can be found at any Oreillys auto parts store. Or any other place that sells Wix filters.
