'73 CB250 - Doing it right this time round.

Cheers fellas.

Mounted the Caliper. Ignore the length of the braided hose, its being shortened now that I know the length that I need.

Starting the long and tedious process of wiring now. Got a plan up my sleeve for the battery, so just making a basic loom until I finalise details of it.

Got some edge guard to put around the tail light to secure it in place, and to stop it hitting against the underseat pan and breaking.

I also put a bit on the curve of the pan to clean it up and to help it from hitting the underside of the seat.

Moving ever so slightly closer til the day I can get the engine buttoned up, and then fired up!

Oh yeah, that's one of the most exciting parts of the build!

Haha sure is, which is why I decided to give up on it for a bit and do something else! ;D


Cleaned and installed the original brake-side rear set. Just need to install a decent return spring and it should be all good!

Would like to replace the rear sets eventually but will stick with these for the time being.
 
Replaced the inner tubes yesterday so now it rolls! haha

I also painted the headlight bucket and the mudguard to test the paint scheme. I think it looks great. Will get some pictured of it up soon.

I put both sprockets on and reduced to chain to the right fit, and dropped my cylinders off to the machine shop to be bored out. Should be back tomorrow so she may be running soon! ;D
 
Started off by testing some paint and the pinstripe tape on my headlight bucket and mudguard. I really could should have used a filler primer but as this was a test I just sprayed both as they were.

Turned out relatively ok so I think I may keep it as it is for the minute and respray it properly eventually.

I then mounted them on the bike. As a whole, the front of the bike is now done.

Need to straighten the switch when I wire it.

I also started on a new rear set brake linkage.

And then I got a phone call from the machinist saying my cylinders were done!

Going to clean and get the head on it tomorrow If I can.....we're getting there!
 
I still need to set the timing, and I really need to touch up taint. Not sure on whether or not to paint the head once fully assembled, or to leave it unpainted and just clean it really well!

Finished up my engine today!

Once the motor was all torqued down I sprayed the head with VHT paint and touched up any scratched that were in the paint.

I know I shouldn't have, but I sprayed my carbs too...will last the first 5 minutes its running until I inevitably get a massive fuel leak haha

Then mounted it all up. Still need to tighten all the engine mounts up but other than that its in.

Looking good! Great progress!

Thank very much fella!

Progress is slowing a little bit at the minute. I recently purchased a race bike to start motorcycle road racing. I completed my ACU race license a few days ago, so have been spending my time playing with my race bike! Never the less. progress will resume soon! ;D

That's me on the '94 cbr400rr...about to be overtaken by many bikes! hahaa

Started bodywork finally!

Filled in a few dents and the mounts for the existing badges. Only managed one side at the minute, hence why all the pics are from the right! hahah

Still got another few passes of filler and primer to go, then on to paint!
 
Moved away from bodywork....my arm is killing me from all the sanding! haha

Had a quick glance over the wiring and started to adjust a diagram I found from Clymer.

Does this look ok to any of you?

My plan is for the running lights to remain off once the ignition is switched on, and then turn on when I flip the on/off switch in my headlight?

I also dont have a kill switch, so would I just connect the wires as if there wasnt one there?

Having a bit of a hard time with wiring. I am less than useless at electrical stuff so i'm trying work through it but its taking a while.

I have hollowed out the starter motor, and planned to put a small battery in there. As there is no starter or turn signals, and all the lights could be turned off independently to help starting, the battery was just going to be there to boost the spark while trying to start it.

Ive ran into a problem trying to find one small enough that will fit inside, and one which I could realistically afford, so im currently looking into running a battery eliminator. I have no real idea about them, but found a 10,000 micro farad one designed for a yamaha sr500 which I was looking at trying out. Can any one chime in?

I've just bought some pancake style filters from an MG to try and adapt to replace" the knock off pods currently on my bike. Im going to clean them up, and try and adapt them to fit like cafePete's "Lucky 7even".
(http://www.dotheton.com/forum/index.php?topic=10532.330)

If the chrome on them doesn't clean up, I can always just paint them to resemble sidecovers for the bike.

Use this in front of the tail light under the seat.

I have looked in to using one of them, just not sure the hump is big enough to hide the battery under....will measure today. Have you had any experience with this battery?
 
Pancake filters arrived today.

Pretty good condition. I sprayed the backs of them matt black just to cover the rust spots I couldn't clean up but the chrome fronts are in very good condition.

The filters were made for an MG midget, so the manifolds are 1 1/2"....which is smaller than the intake on the standard carbs, so im gonna widen them up a bit.

Pictures to follow.
 
Pictures of the filters....I cleaned the back up using a brillo pad, then put coat of matt black paint on the back to clean it up.

<img src="http://imageshack.us/a/img706/9240/tjaz.jpg" alt="Image Hosted by ImageShack.us"/>


The fronts polished up quite nicely aswell!

<img src="http://imageshack.us/a/img69/5089/r7py.jpg" alt="Image Hosted by ImageShack.us"/>


I got the manifolds for them too. They seemed to leave exposed gaps, and came without gaskets. I wasn't sure if the holes were meant to be left after the gasket was on, or they were meant to cover.

<img src="http://imageshack.us/a/img843/7606/8wnz.jpg" alt="Image Hosted by ImageShack.us"/>


So I made my own to cover the gaps.

I used a spare rocker cover gasket I had lying around, and just traced and cut a pair out.

Just upgrade your regulator so it doesn't get cooked. As long as you don't need a starter, or leave the lights on for a long time, your good.
