Rolled a few dents out of Bill's fenders today. Then stripped it down a little more.
I'm working on the wheels and when I disassembled the rear, the spoke flange on the pulley side is loose and spins freely. Replacing it with a good Shimano and larger 21t sprocket. Still trying to round up a few spokes to replace some too small ones.

Yes, SB, after paying Gary of Team Bike $15-$20 a fender, I decided I have to own one. I made it a few years ago and have gotten some good use out of it. Just turn the big valve handle on top to open it up, insert the fender, close the gap and roll the steering wheel back and forth a few times to get the dents out. Keep tightening the clamp as you go. I make a lot of my own specialty tools and this one was a fun challenge. It's pretty simple in design, but as you well know, there's no small jobs. It takes a little practice and you have to be careful not to roll over the edges and flatten the bead, but I've had real good results so far. I made everything and had Dan contour the rollers.

Good idea, a home made English wheel of sorts. If I ever have a need for one we may have the parts in the shop at work. Looks like a few of the conveyor parts we use regularly, and a handle from a riser gate valve.

Bill came over Saturday morning for a couple of hours and we stripped the rest of his frame.



Lots of cleaning to do. Going to remove some unneeded brackets.
Bill went home and then Ray stopped by and brought a nice carb, head, layed back seat post and speedo with him and took the cylinder with valves, piston, and exhaust elbow to do his magic and some porting. He also showed me how to disassemble the fork tubes.
Then Dan came over with his Briggs bike and helped us figure how to lower the forks an inch or so.
Going to get new fork seals and Dan will make lowering spacers. I'll post photos of the procedure and parts needed when we start putting it together.

Dans Briggs bike is nice! Lots of specail stuff done to it.
It's always a pleasuer to sit down with Dale and these guys and share ideals.

I started reworking the exhuast elbow by smoothing and rounding out the inside, inproving the exhaust flow.

I also placed the air/oil separator in the valve cavity, this helps to lubricate the valve stims,and relieve crank case pressure.

Thanks Buddy.
I finished the cleaning and reshaping of the intake and exhaust ports.
Sent the cylinder, valves, head and piston to the heat coating shop. will post pics of them when I get them back, just a little info about the coating.
Applying a thermal barrier and dry film lubricant can and will help lower engine temperatures.
