My first large to me bike in 1973 was a 66 305 scrambler. Tank and covers were painted dark green metal flake by previous owner. Great machine for the road I remember. My friend had a 73 cl 350 and we took off-road down into the Spokane south hill bluff. Took both of us to push it out of there. His Honda would climb out but I didn’t have the skill to get mine out. Pretty much zero suspension compared with today bikes of course, but were the best and most dependable back then made by any manufacturer. I got a compression fracture in cervical vertebrate from small high speed whoops that day. My doctor told me 20 years later, he could see it in an X-ray. I wondered why my mid back hurt for years after that ride.
Anyway, your metal epoxy repair on your cases looks fantastic. Top quality repair.

Nice work - I've spent a lot of time in 305 engines...is that Tech Steel a regional thing, or is it available everywhere?

Thanks guy's the Tech Steel is a Canadian importer, yet it must be available from some US based business I am sure.

There are other products that mimic some of the Tech Steel properties, yet this one has the quicker set up time of 15mins and a 1 hr. full cure. Most products are 24 hr. cure times and longer set up times. The 500 F temp rating was a difference too. The JB Weld was not the same, yet there are likely other products that offer these specs now.

Google Tech Steel for more info.

J-B Weld has an extreme heat product — 1000* F. I have no experience with it, though.

I found a business who offers both Vapor Honing and this other technology Laser cleaning process that can be tailored to the job. It should be ready next week and I am excited to see how the cases for sure clean up, yet many smaller parts (15 in total) plus the complete carb set.
I spoke with my local CVMG member who has a home based machine shop and he can do the machining work on the motor and pressing bearings on and off parts. I found a set of new OEM valves and all new valve springs, so the top end should be solid with that crazy 4 roller bearing support system.

Fantastic crankcase repair, great work ability and good product, which I don't think is available in Europe.

I was surprised at the finish and turn around time for the vapor honing and laser cleaning of 26 pcs of the motor, side cases, carbs and all at a reasonable cost. He used the laser equipment to burn away all the old dried on oil discolouration inside the motor pieces. This gave him cleaner parts to vapor hone with less contamination of the media he used there.

So as new replacement parts for the motor are arriving now and my friend with the machine shop garage has confirmed he can do the work later this month on the over bore and the head work now. I have all new OEM valves and both inner and outer valve springs for replacement parts and measured and confirmed the cam journals and lobes meet factory spec. The rocker shafts are within spec too. There is wear on the pads of the rocker arm where it rides on the cam lobe, so I am thinking of a hard chrome resurface when the time comes. The NOS parts new would be $600.00 Canadian to buy from a supplier. I know I can have that done for $200-250 Canadian for the set of four in a hard chrome finish on the pad.

So here are the pictures of the parts as picked up today.

Seen vapor-blasted stuff in Brit bike mags; seems common over there. It comes out looking so good, I wonder why it's a bit rare to find somebody over here who can do it.

I had a guy in Tucson vapor blast the cam cover for my CBX a couple years back. He did great work. (sorry I don’t currently have access to the best pictures that show it). But I will say that the texture provided by the vapor honing process is really, really nice. It’s not a smooth, polishable surface, but once you see it, you won’t want to polish it!

Yes this business is quite unique offering both technologies for case/parts cleaning. That laser cleaning machine/process is something else too, the way it burns away oil residue or paint off a surface is impressive. Vapor honing clean parts must make the process on the media easier and last longer.

Those heads on this particular style of motor is (for whatever reason) one of my favorite one-piece machined castings. There's just so much going on with it.
1997 Valkyrie- Light Cutomization, but Too Busy Riding
1980 KZ1300- Bike's Haunted
1976 GL1000 (Yellow)- It Runs (Poorly) and Doesn't Leak (Mostly)
1974 Velosolex 3800- Better Than Walking
1972 CB750- Broke the Chain And Ate the Motor
1969 CT90- The Most Fun You Can Have on 90ccs.
1965 CA77 Dream- Needs a Full Teardown, but Complete

All advice I give is only valid until an expert corrects me.

That head does look a little "art deco" and the abundance of fins and it's shape does contribute as well. It is quite an engineering set up with overbuilt being the order of the day for sure. Four roller bearings of a decent size support two halves of the cam pieces, which each notch into the main center cam chain gear, these little cam pieces are only 3 " long.
The complicated design of that upper section of the cast head and those roller bearings all contribute to two different locking systems to hold the left and right cam pieces into that central cam chain gear.

So some more progress at a snails pace these days with old man winter still hanging around. I did mange to get my metal body parts bead blasted recently and I also cleaned out the gas tank. Someone had lined the tank with Kreme previously and they did a poor job in the prep. When the tank was bead blasted to remove the paint, it knocked pieces of the liner off the inside of the tank. The tank also had two sections with lots of pin holes and larger ones 3/16 across in the bottom.

I decided to solder the holes and with a propane torch and with a roll of plumbers solder I was able to fill all the offenders in well. I am just in the process of cleaning the tanks interior. I used Acetone and Lacquer thinner to dissolve the Kreme and now with Evaporust to kill the remaining rust inside and then install a new POR15 liner correctly. I chose the POR15 tank liner material, since it has a good reputation and is impervious to our lovely Ethanol laced gas.

So here are the parts cleaned and stored inside to prevent flash rust, until I can shoot some primer and then the paint in the spring. Some pictures of the tank after I soldered the bottom closed again and then filled with glazing putty to smooth out the bottom area again.

Can't wait to see this one start going back together. Meanwhile, it's fun just sitting back watching you spend money!
