Update?...You got it.
Well i took my bike to LA to have exhaust built for it. Hopefully a nice 4-4 stainless set of pipes. So i dont have my bike to work on. The seat came in the mail but i cant doing anything with it until i have the frame back. I think i might start working on the engine since i cant do anything else. So im starting to collect parts for the motor.
I have a ported head and a hotter 650 cam. I just received a set of CB750 pistons modified to fit a 550 with a bigger cam. It will bring my bike up to about 592cc. Pistons were ceramic coated on top and the skirts were coated in teflon.

Sorry nothing to exciting, but as soon as the guy finishes my exhaust there were be pictures for sure.

Are those modified CB750 race pistons?
Never seen valve pockets that deep in stock 750 pistons. (or piston crown thick enough to mill them that deep)
I modified outer edge to fit 550 combustion chamber, worked well for over 70,000miles with a PIPER fast road cam (still have cam card somewhere, I'll dig it out and post specs when I find it)
Nice looking exhaust, any baffles in it?
 
Re: CB550 alloy sprint

sweet build man! I love your front fairing. It's good to see that your commiting fine detail to this bike. The whole shiny look is gonna be awesome when your done. Do you have any plans for dressing up the engine at all. With all that body work I feel like your gonna need something to really wow people. Like yourself I dished out some cash, but mine was for chrome. Here is a pic of my engine. Might spark some ideas :)

Re: CB550 alloy sprint

Very nice srgtbear. Im not sure what im going to do about the motor. I think i may keep it silver and leave it alone. I am going for an old school cafe look and the never really seemed to do much to the motor as far as looks go. The bike is really going to revolve around the tank, seat and fairing and i dont want to much shiny bling on the bike.


The pistons are standard cb750 pistons modified based on an article called "Gentleman's Express"in a 70's motorcycle magazine. The pockets were cut a little deeper for the hotter cam and the tops were ceramic coated and the sides are teflon coated.


The turbo 750 on that web site is the one that carpy is so proud of. The guy who built my exhaust made the turbo for him.
 
Re: CB550 alloy sprint


After a long day on the road i made it home with enough sun light to slap on the tank and seat and snap a few pictures.

Re: CB550 alloy sprint

The bike's looking very sharp, ffjmoore. Love the raw stainless and alloy together.
 
Re: CB550 alloy sprint

cool man !! Your bikes name should be back to the future. Are u planing on painting the farring or the tail section? You are going to blind people when you come down the road on sunny days ;D Nothing butt a flash of light will they see lol
 
Re: CB550 alloy sprint

there will be a little paint on the aluminum but not enough to save the glare. Rims came in today with ss spokes. SO pretty. Dont think im going to lace them up yet as i dont have cash to drop 3-4 bills on tires mounted and balanced. I also got a steering damper from mikesxs. Ill start fabing up some mounts for that.

Also had a friend drop off a bike he wants me to help restore. I guess ill start a scooter/small cc club.

Re: CB550 alloy sprint

Nice rims . Are u traying to cut weight? How does buying aftermerket rims work? as long as there within speck its ok. Do you just order size 18 inch rims and run the original hubs?
 
Re: CB550 alloy sprint

Trying to cut weight? Yes and no. When i put things on the bike am keeping weight in mind and one of the best places to loose weight is on the rotating mass. Plus everything else on my bike is aluminum so why not the rims. I looked around to see what size people were running and went with that. They are a little wider then stock rims. I ordered from buchanan. You tell them what size and what hub its going on and they drill it accordingly.
 
Re: CB550 alloy sprint

You must of spend a pretty buck then. so you tell them make and model, or just how many spokes your hub runs?
Ps you must live close when your bike is up and running we should plan a local ride with all the dtt locs .
 
Re: CB550 alloy sprint

Little update
Went to lace up my wheels and the rear hoop was a 2.15x18 not a 2.50x18. They dont do returns on custom drilled rims so i had to buy another rim. The 2.15 rim is for sale and im selling it for 150 shipped. They cost 215. So while i wait for my new rim i had my hub polished and then laced up the front and put some rubber on it. Im also still working on mounting the seat and cutting out a seat pan. Took the cylinders in to be bored and they quoted me $400 for an over bore. F, hot rod motors are spendy.

I weighed a bunch of parts to see where im saving weight. The rims and spokes save me around 2lbs per wheel.

that pretty much brings this thread up to date.

Re: CB550 alloy sprint

Wait.....they drilled the wrong rim for your and yet won't make it right?
Did the ymess up or did the wrong one get ordered on your end. Not picking or poking, just don't want to do biz with anyone that'll leave a brother hanging....

That front wheel however looks a treat!
 
Re: CB550 alloy sprint

It was a miscommunication. She wrote down the wrong size, I didn't catch it, I signed the invoce. So I can't place the blame all on them. Plus I didn't catch it till months later. Oh well live and learn. I still recomend them
 
Re: CB550 alloy sprint

So after a long debacle the Correct sized rim was shipped to MY house. I Laced it all up and trued it. I was going to take it to have the rubber put on tomorrow but i forgot that i work for the next 3 days, so wed it should go back on the bike nad then i will move on to bolting down the seat, trimming the seat pan and then getting it upholstered.
