CB72 freshened up

After last years season, the CB72 had its motor taken out because of a gearbox problem, and it pretty much sat at the end of the workbench for the whole winter.
A couple of months ago, my dad fixed the gearbox, and as we got the bike out of the corner, we did some slight modifications.
The rear wheel was swapped for one with an original hub, and a rim that matches the front. A front fender was made. (the dutch honda moped freaks might recognise it as a rare C320 fender) And the tank got some new stickers.

and the top yoke was swapped for one that has been welded shut and ground down to look like an original CYB yoke.

It is still a racebike, so it shows signs of use, but these little things just freshen the bike up a bit and make it look more like the honda's we all know from back in those days.

Pony tank

Pony got some new tank emblems.

Seems appropriate for my life right now.

A tire change and some night shots.

Got the new white wall in from Jegs and put everything back together.  

No more wobble!

The struggle.

The help.

Thanks for the tire iron help, C.

Night shot Benly.

Night shot Pony.

New tank, carb, and air filter coming soon.

Old is better.

  I like it.

Master locks and one West German lock w/key.

Thanks Tom

Pony Mantis

  The pony is legal and ridable but after a week or so of messing with the carb, asking and searching forums for advice I decided to give up and do what Xlint performance Guru told me to do. 

Buy a 36mm Mikuni.

Not for aircraft use.

Duly noted.

My students know I like to read about brain function. . . one of them has a parent that works at a publisher so she hooked this up for me.  I read the first chapter and am already hooked.  

An examination of creative thinking.

This guy jumped on my from the plum tree a few days back.  

clutch swapping

With the SS50 race project being for sale, the chance exists I could actually sell it to someone and I didn't really want to loose the Takegawa clutch that was on that motor. So I decided to switch it over to my 110cc engine.

Now the motor is rebuilt...again... with a 5speed gearbox, Takegawa clutch updated to 4 plates with some leftover china junk.

But that meant I had to start building a new engine for the racebike.
SS50Z cases, 5speed gearbox (and a spare 4speed close ratio) clutch moved to the gearbox input shaft by using chinese parts combined with a little bit of Kitaco, 85cc piston (allowed by the SAM) on a 12v crankshaft.
I have some plans for the head, but I'm not that far yet.
yesterday I did start on something for the breather, made it out of a CL72 filler neck that will get a bung welded on the rear to attach a hose.

It looks way high now, but imagine an upswept exhaust running just underneath that.

Static Timing?

I usually use a gun and just get really oily but this time the XL350 engine is too much.

Static timing is more accurate anyway

There are some decent ones out there but they are not cheap.

$50+ from England 

$35?

Hmmm....

Double hmm...

This is the best thing I found from someone on a forum just now. 

Good idea!

I thought of the same thing......only my flashlight cost $1--with batteries.

The alligator clips were from a broken set and wiring around 10 cents?

Anybody else want one?  

We could have a timing light making party........

Oh, am I the only one that thinks that sounds fun?

Okay....
