Once all that is done, I'll put it up for sale.
I wouldn't be so sure about that!  I bought mine with similar intentions..."Hell, these things are ugly, right?"  Mine was cheaper but further from running/riding.

3 years and 10,000 miles later, this ones a keeper that out accelerates, out brakes by far, and out handles any other sohc4 (I think I am up to 13 or 14 now?) I have ever owned.

Valve guide concerns are real.  Mine are shot at 28,000 miles.  Still, does not keep me from riding, ignore the smoke and add a quart every 500 miles or so.  It will be "worth it" to go through the cylinder head when fixing 'em.
If it works good, it looks good...

Nice F'er, Ron!  I like your plan.  See if you can part with it when you're done.  Now back to those CB5XXs!!

Thanks, Don.
Yeah, I've been making small, incremental progress on them but the 500 will get almost all of my attention in 2 weeks.  I'm supposed to be done with these apps by May 23, so I plan to spend the weekend afterwards 'wrenching and riding'.

Ron,

Congrats on the new bike!  I would have bought that in a heartbeat!  Wish I was closer to you to take it off your hands.   It seems these SOHC toys are like tater chips......

No, Stella is mine and I do ride her as often as possible.  As a matter of fact, I intend to ride her into the office tomorrow.

Logan has been busy with college but is now scheduled to take the MSF class in 3 weeks, since he's out of school for the summer.

Ron,

I can't remember if I mentioned this before, but with the less extravagant CB500 build, you might want to source some small crash bars since Logan might do the inevitable tip over on his first bike.

OUCH!

The likelihood of a tip over (even a garage tip over) for a newbie's first bike is high.  Almost when and not if.  It even happens to more seasoned riders every blue moon.

Last night, I had the chance to apply the first coat of paint stripper to the tank and found something interesting.  It appears that someone, at some point, hand-painted the stripes and red area onto this tank...probably in an attempt to emulate the original decals on the tank.  It's almost a shame to paint back over it.

Looks like that tank has had a few lives.  I wonder why people don't strip a tank down to metal, and just paint over it.

Because paint that is in good shape makes a great foundation for the next layer. Its like vinyl flooring in a way. Too many layers becomes a problem down the road. But 1-2, not so much of a problem as long as they're in good condition.

Good point.

I was reacting more to people who pile on layers of paint and bondo (instead of repairing metal).

So now I'm heading back to the 500 to finish it up because I've sold the 750 Super Sport.  Wait for it...I sold it back to Bill Benton.  :)

I took Stella for a 50 mile round trip ride to Bill's house and back today to pick up a few items I needed for the 500 & 550.  While I was there, we got to talking about the 750 and I found out that he had actually wanted to buy it back from his buddy.  And I had assumed that Bill had passed on the bike before it was offered to me but that was not the case.  So I sold it back to Bill for just what I have in it.  He's going to finish fixing it up and give it to his buddy who's been helping Bill get everything straightened up & organized around his house.

But I did get a free, sweet new BentOn Racing t-shirt out of the deal, too. And above all, the bike will be going back to a good home that will put it out on the road where it belongs.

LOL, yeah I could have made some money off of it.  But Bill really should have had the first opportunity to buy it anyway. 
To my way of thinking, doing something to help a friend is worth way more than money.
