CB 450 project done... need jetting/gearing tips

Re: CB 450 project underway!

Thanks, it was his dream bike as a kid growing up in the 50's. He thought I was restoring it for my wife's boss and he begged the guy to buy it on a couple of occasions as I was restoring it (luckily my wife's boss played along with our little lie). At 42 yrs old, I had never seen my dad cry..... He cried on and off several times that day. ;D He keeps it waxed and covered and he puts a towel on the polished stainless steel floor board EVERY time he kick starts it. He tells everyone he meets about it. I also have a '58 Eagle that runs and I will eventually restore it also someday.
 
Re: CB 450 project underway!

After changing my mind several times on how to build/mount rearsets, I finally started cutting metal. Cut up a couple pcs of 1/8 steel and drill a couple lightening holes and a 1" dia hole for my peg mount. I made the peg mount out of 1" dia steel tapered it for weight saving and drilled a 3/8 dia hole thru it. I am going to fixture it up with a 3/8 rod spanning thru the frame to hold the parts in perfect alignment, then I will tig weld the plates and bosses in place. Should be strong yet fairly lightweight.
 
Re: CB 450 project underway!

Clamped up the new parts with a 3/8 shaft passing thru to insure alignment, then tack welded bosses to plates. Removed and finish welded off of the bike. I think they came out pretty decent. I weighed them for future reference and they weighed .21 pounds each. (stock footpeg mount weighs almost 1.5 lbs)
 
Re: CB 450 project underway!

Got the rear set mounts finish welded in place, now time to build the actual rearsets.
 
Re: CB 450 project underway!

that looks real clean. out of curiousity, why didnt you grind off the old mount and just start with a new smaller piece?

I thought about that many times, but I kind of still planned on using the passenger peg mount as my exhaust hanger. I am not totally happy with what I have now, but I kind of got pissed at myself for wasting months thinking about how I was going to mount the rearsets and just said screw it and started making parts. Time will tell if I end up staying with this setup.

well atleast you did a good job
 
Re: CB 450 project underway!

Got some lightweight 4130 steel brake and shifter pedals fabbed up. Without the bearings they weigh .41 lbs total. They don't look as cool as some new fangled aluminum jobs, but I think they will look OK once painted and they are designed to work perfectly with my frame/rearset configuration.

Re: CB 450 project underway!

Well, on one hand, I like the trick looking rearsets that have been taken off modern crotch rockets, but on the other hand, many of them look out of place or mounted in a cobbed up fashion. I guess I will reserve judgment until I get the bike completed and go from there. As it stands now, these pedals place my feet at optimum angles yet clear any obstacles (swingarm bolt, kick starter, back of engine case, top of stock mufflers). The shaft running back to my brake shoe arm will be straight and I will not have to use any additional linkages for it.
 
Re: CB 450 project underway!

I agree. Although I just bought some rearsets off of a 2005 R6, the best way to go is to fab your own. Unfortunately, I don't have that capability so I'll take what I can get.
 
Re: CB 450 project underway!

those are killer and it only adds that you made them. i cant wait to see them installed
 
Re: CB 450 project underway!

yeah those are sweet! I'm sure they're going to feel real solid on those brackets too, real nice setup man!
 
Re: CB 450 project underway!

What is the best way to remove an engine from a 450 only using one person ? Floor crane? I am abot to unbolt it and it looks heavy. Maybe I can hook my floor crane to it and weasel it out?
 
Re: CB 450 project underway!

unbolt the motor... you will see what side the motor slides in from... then just lay the fram on the side (towards the side it comes out) lift off the frame... boom motor out!
 
Re: CB 450 project underway!

i think those rearsets are the shit! look at pics of old (50's) race bikes, the controls were basically bent pieces of aluminum, that's what cafe is all about... make it the lightest possible thing!!!
 
Re: CB 450 project underway!

It's easier to remove the engine from the clutch side. I used a scissor jack from my car to hold the engine up as I unbolted it, then I just lifted it out. It was heavy, but I'm only 5'7" and weigh 135lbs so I'm sure you can lift it out :).

Laying it on the side sounds like a better way to remove it though.

Well, I am keeping the pedals, but will likely cut/grind off the stamped stock mounting gussets as they just look too clunky. I will weld on a lightweight 4130 tube structure in it's place.

Laying the bike on it's side is not going to be easy since it is on a rolling cart, I am guessng I can wheel the engine hoist up to it and winch it up, over then out of there. Looks like it will have to wait until tommorow night.
 
Re: CB 450 project underway!

On a 450, you can just lift it out. It's not too heavy. Laying it on the side is easier, but it's easy enough just to pick it up.
