Went and picked it all up for $74. That's right I got a dollar off. I'll try and put it all together next week when I mount the tires.

Starting to get my sweet seat hoop ready to weld in. Tire clearance is for pussies. Now I need to review some Ichiban Moto videos on how to make a badass brat cafe scrambler seat. Knee dents are in the works too.

Steering stem is longer as is forks. 1979 is DOHC. The forks are better. Wheel and caliper are different. If it uses the five bolt rotors you can upgrade the caliper to two piston
Any more info on the caliper situation for upgrade? The one I've got should be fine for now, but can't hurt to look around and see if there are any reasonably priced options available.

It's the 5 bolt hub by the way.

Look for a 1981-82 cb750F or cb900F dual piston caliper and mounting bracket.

it looks like this:


I would measure your fork leg bolt spacing and post it up, I think I have a 900F bracket kicking around the garage somewhere I can measure for you to confirm that your fork will accept the bracket.

The bummer about those spoke wheels with the 5 lug disc is that they don't usually accept a dual disc setup - the other side is not drilled and I don't think there is enough meat in the casting but I could be wrong. Why this is a bummer is that those early solid 5 bolt rotors are prone to warping under hard braking, and if the dual discs warped, what chance does the single disc have? If you are feeling spendy, see if you can find a later rotor that looks like this:

in my expirence I have had plenty of the solid ones warp, but very few of these later ones.

There are further upgrades, and hopefully jag will chime in here, that use interceptor dual pot calipers or cbx dual pot calipers with bigger pistons and vented rotors but this is the simple basic cheap bolt on.

extend your hoop, or put some kick up in it. And use it to mount a rear fender, even a small one. the biggest mistake I see people making is they put the crossover of the hoop at the highest point in the tire.

That was a joke. Should have put a winky face in that post. I had a piece of my old tt500 frame laying around when mocking up the seat and fender. Couldn't resist. There won't be any hoop on this bike, I have a frame to swap everything over to with the factory brackets.

I'll measure the fork leg tonight and see. For now I think this rotor should be fine, but I'll keep my eyes peeled for a future replacement. Thanks for the info so far.

A buddy let me borrow a cb750f seat to see if it would work. I just wasn't into the 550f one I had, and this one should work perfect. Fortunately for me, he had no use for it, so it was gifted to me. Needs a new cover and a little foam work, but should do the trick.

I almost put this bike back to chopper thingy glory to put up for sale, but just couldn't do it. Instead I went the dumb route last night and swapped frames to the one with stock brackets and all of the necessary bracing.

After about 10 minutes we had this.





About 1 and half hours later I finally got the stupid rear wheel free from the swingarm and one motor mount bolt that just wouldn't let go unstuck. So much for an easy swap.

I took this pic this morning to show the aftermath of scattered tools and parts.



Then threw the tank on and seat just to make me feel like I did something. Good news is that I have most of the parts needed to get it back together quickly. Bad news is I still need to get the rear axle free from the brake plate. It's stuck pretty good so I've got it soaking in penetrant for the time being. I'll get out the torch bottle and see if it can be freed this evening.

Almost forgot, I cleaned the carbs a couple months back. Putrid fuel left in the bowls, but other than that a little dip in some Berryman's cleaned them up nice.



Two of the float valves were clogged up and the pivot pins were stuck.









Still need to bench sync before install, but they are a few minutes away from done.

I've been building a 24x24 garage all while tinkering on this turd, so progress has been slow.

Lots of fiddly little work done but it's now riding on Avons, and very close to being road worthy. Looking at some Hagon shocks and a Delkevic full stainless exhaust, but money is tight and I'll have to wait a month or two for those.

I know there's a block of wood there, but unless I lengthen the kickstand, it leans too far over. The longer cb750 forks need to be addressed.

I'll get it running and riding first with the chopper setup before making any changes

If everyone did the above first the world wouldn't have lost so many bikes,,, a tip of the hat to you sir :)

I had every intention of following that advice until I tried to remove the rear wheel. It took forever to remove the axle due to it sitting under a tarp in someone's yard for a year or so. The more I took it apart, the more I realized it would be only a small amount of work to convert it back since I had another stock frame to swap over to and all of the parts needed to make it happen. I've got to get this road ready and some test miles in before next month for a trip to the Lake O Pines Rallye.

Long while for an update. Lots happening. I'm moving in less than a month(long story), so I've been clearing out projects and parts so I don't have to bring as much crap with me. I should have purged this stuff a year or so ago, but when a buddy offers free storage you take it.

Anyway, the only bike I'm keeping is this cb550. Last night I got a pair of nice Koni shocks that just need some fluid for $100 from a buddy. Next up is exhaust. I've got the cut up stockers but they are fugly as hell. The Delkevic full stainless system looks to be the best choice for my money, so that's probably the route I'll go.
