If I were you I would talk to Mark Masa - 330 714-6453 is the number I have for him. He is the JD guru (one of) and is usually willing to trade if he can. He posts here regularly and I am sure will leave a message.

I built a 1925 JD for the Cannonball and found out the hard way that it has more one year only stuff than probably any other year HD.

What to do next all depends on what you want to end up with. 100 point restoration, bobber/cutdown, or just a rider that looks like a cool old motorcycle without much regard for correctness. I can tell you that your rear cylinder is a 1925/26 and your front is in the 1927-mid 1929 range. The intake housings are different from each other but will work. The rocker arms are 1928 style. The frame is a 1928/29 and the trans and rear fender are 1926-29 style. The trans will have a raised pad on the rear stamped with either 26-something (1926) or 27-something (1927) or will be blank (1928-29)
It's all good trading stock if you do lean towards doing a correct restoration. If you go that route, doing a 1928 may be the way to go since the frame is 28/29. I say 1928 because there are a few parts on a 1929 that are DIFFICULT or EXPENSIVE. specifically the dual headlights, horn and dual exhaust.
JD stuff is generally easy to find and there is good aftermarket parts support from people like Competition Distributing, Replicant Metals and myself just to name a few.
It's a decent looking pile of parts to start with, but like I said at the beginning, you need to decide on the end goal first.

Thanks Jerry and Mark,
yes it looks like the bike i going to build with the parts i have and need to get will be like a race bike( like this picture) so im going to start with the motor and i would like the cylinders to be the same, i need a 1927-1929 range, if you know of one i will trade my 1925-1926?

Very cool bike, depends how much you want to do yourself really! Rip the whole thing down to the frame and make sure it is straight (the seat bar casting looks to have been hacked up). Jerry has an EXCELLENT thread on his 25. Then get to work on finishing the engine, how far over are the barrels bored? Jon Nueman sells venolia pistons that work pretty well. Motion Machine can do your barrels (https://www.youtube.com/watch?v=cDfueUhbGqs), but the valves will probably have to be done somewhere else. If you don't care about correct-ness you won't need to find the one year fenders and one year tranny...

Go get yourself some books!

https://www.amazon.com/gp/product/0486436713/ref=oh_aui_detailpage_o07_s00?ie=UTF8&psc=1

The link above has a book with the best print of the original factory J/twin engine rebuild I can find. Also it has great details about other stuff

I have the 29 riders handbook too and that is real handy for cutaways and settings

One of those books has a sheet with all the clearances you should check on your engine. Happy bushing! Keep a lot of bearing bronze around and never assume it was done right until you go in and check yourself.

back on the tanks, soft soldered the gas tank up with an electric iron. the iron was a little on the big side but it was all we had. holds pressure and good enough!

Nothing like getting a wheel finished, putting on the tire, and then putting it on the chassis. Looking good!

Hi GWW, i used 60/40 and a tinning paste flux and also ruby liquid flux, work well with an iron. i also just used KREEM in the tank to seal them all up. i have used the KREEM on a 45 HD tank 20 years ago and still looks good inside the tank!

you'll probably find one like Al did. fwiw, Al is exploring feasibility of having new rods produced. i am on Al's list. i want a spare set just in case...

Sure. I've got one. Looks like you need the socket for it too or is it just not pressed in?
Need the arm that fits on the cam rack?
PM me.

Hi Mark, yes i need the socket too and the relief stud, i have a cam rack. how much?

MMasa

Pm me with your email address and we can discuss the details.
I figured that you have a cam rack, but do you have the decompression part that fits ONTO the cam rack?
This is the part that the stud acts upon which in turn lifts the exhaust cam followers and valves relieving the compression.

I am so lucky! just look at the can of starting fluid next to the burn spot! there is a God that looks after my dumb ass... So after i stopped shaking after a few days i started the bike and it ran just fine but Im still in shock over the hole mess. i will start taking the bike apart for painting in the few weeks.
