Before and After: Reed Valve Assembly

[schimmelaw]

81' 430XC street legal motard conversion in a slow but steady rate of progress.

Photos 1 and 2: The aluminum oxidation in the reed assemblies required a blasting in the sand cabinet to clean. I went ahead and removed the stock black paint on the exterior due the chipping and grime.

Photo 3: Interior portion of reed assemblies are corrosion free and clean. Shot some new black case paint on the exterior while I was at it. New gaskets, new ssteel and aluminum mounting hardware.

Photo 4: Sand blasted head and cylinder. (A project I have been fooling w/ for the last 4 or 5 wkends now. Glad to have that over w/. My poor little compressor - I abused it.) The above reed parts. Nickle plated exhaust manifold, gasket and its ssteel mounting hardware. Nickle plated Retro Rocket pipe.

Photo 5: Business end of the reed assembly bolted up.

Another component refurbished, wraped up, stashed in the box and ready for reassembly.

OK Schimm... amazing work once again, and again I have questions:

1) nickel plated retrorocket pipe.... did you do it or did you buy it that way fromVintage Iron? Electroless nickel? How many micro inches in thickness .0004" or thicker? If I may beso bold what did the Nickel cost you?

2) Did you clear coat or clear h-itemp coat the jug and the head?

3) New black paint or powder on the reed cage assembly? Hi Temp? Brand?

4) reeds? New and where from? Do you have any detail pics of the two triangular reed cages themselves?

5) Brass bolts with copper or brass washers? New? If so where did you get them? Size and pitch?

Good ...no Great Stuff Schimm..

Tim,

Thanks.

Bought the pipe from VI and had it plated locally. A friend runs a local plating company - he did it for me. (As well as my other plating needs) Tried to talk me out of it b/c he said it would turn "yellow". I didn't want to fight the inevitable rusting - so he "douple dipped" it. Don't know what that really means but he seemed satisfied and I'm happy. I just buy him lunch and give him a large bottle of Canadian Club and he's happy. Never asks for a dollar.

Cylinder and head have no coatings on them. Raw aluminum post bead blasting. Hopefully, w/ the bikes intended use, I'll keep them somewhat clean and stain free.

Photo 1: Paint was PJ1 Fast Black Case paint. Satin black finish. Part #PJ1-16-SAT.

Photo 2: Reeds per request. I don't know what brand these are. In it when I got it. They were pulled and cleaned and reused. No fraying, cracking or tears = reuse. 4 months ago I might have bought a new set. Now, I'm going to go w/ what I got. (This freakn economy is slowly killing my discreationary income!!)

Photos 3 and 4: Just a couple of close-ups of the intake tract minus the aluminum oxidation/corrosion.

Photo 5: Nickled exhaust manifold mounted up.

Allen bolt sizes (appropriate sized stainless flat washers used on all bolts):
4 @ 6mm X 20mm length 1.00 pitch - exhaust manifold
5 @ 6mm X 23mm length 1.00 pitch - reed valve assembly to cylinder
4 @ 6mm X 30mm length 1.00 pitch - cap of the reed valve assembly (these are the aluminum anodo ones pictured - for fun)
2 @ 8mm X 25mm length 1.25 pitch - rubber carb manifold

I have wondered if the rough surface/pitting in image 3 and 4 ( intake Tract) above would benefit from polishing and smoothing out.

I have bead blasted mine and they are virtually identical to yours as far as the pitting. Any thoughts on this?

As far as the pipe goes your Nickel looks sweet. I have toyed with the idea of getting a Vi pipe for my 390 project but George says that he is working on his molds and dies for an Uptite 390 Racing pipe. Plus I want to do the 420 conversion which requires the pipe to be cut.. I wonder when George will have his pipe ready to sell?

Have also thought about electro-polish vs. Nickel plate and/or a clear hi temp powder for protection, especially on the Jug, Head and Pipe....


AAAARGH****************************************! to many great ideas and now I see your amazing work... I need to win a lotto or something****************************************!

Thanks for the detail information... You never let us down and continue to amaze and inspire!!!

I think the pitting in the intake tract is too deep to try and grind/polish out. Its just casting flaws behind the reeds anyways. I'm going to go w/ it as is. To fix it, I think you would have to weld it all up then get in there and start grinding. Way too much trouble for my use.

For this component rebuild I don't have much $ involved. Alot of hours standing over a bead blasting cabinet - but no money to speak of. Gasket kit from Phillip a couple months ago, some stainless hardware, can of paint and spark plug are the only things money was spent on.

More labor (which I enjoy) than anything else.

Thanks Schim.

Your project is getting my restoration juices flowing!

Damn this economy, where is our bailout

Damn nice work Schimmelaw for low / no budget.

What kind of blast cabinet to you have, I'm in the market for one.

Actualy, it belongs to my neighbor from down the street. He bought it 4/5 years ago from a local pawn shop for $40.00. He bought it, brought it down to my house for storage, i've used it ever since. Even had some blasting material in it to get me started. I love my neighbors, such good guys.

do you find that your nozzles/ tips wear extremely fast? I have a Craftsman bucket sand blaster and the tips wear out very quickly.
