Engine barf.

Options..

Tippitty-tap. 

 I need a cam chain riveting tool.

"Mines" is too damn big.

The snug down was essential.

Oh, how the Honda bond does cure.

 Pretty.

Clean.

 Dental tools.

Zip-ties. 

Re-build Set-up.

Preparation.

Maybe santa will stop by tomorrow and help me finish up.

Cam chain went swimming earlier.

Ready for cylinders.

 If there is an arrow on the piston, point it toward the exhaust.

If there is IN stamped on it, well then that faces the intake.

 ９０パーセント準備だな。

Perfect song for an X-mas eve alone.

Honda CB160 Piston Ring Installation.

I have enough bandanas for now.

Back to motorcycles.

Piston ring install.

I wasn't sure if I was going to have to adjust the rings so.....

Push the ring in.

 Measure the gap.

(CB160= .15mm~.8mm)

My new rings were pre-gapped at about .18mm.

Rings must be installed with the manufacturers marks facing up.

Order of rings.

The oil ring very obviously belongs on the bottom. 

Piston rings marked with an "R" or a "T" are the top ring.

Ones marked with an "R2" or "IT" go in the second position.

Point of caution:

The packing grease from these 40+ year old rings had become tacky which prohibited movement once installed.

They were removed, cleaned, lubed, and re-installed.

What I did on top of what I should have been doing.

It's finals season.

One of those nights.

Garage night-->Purge.

Making space in the garage.

Engine inside.

Frame out.

Magic.

Shelf.

 I miss this little one.

Moyou had a freak out after Nate and Hutch left.

 What?! Hugh?!?

Thanks Bigcity

Do you want colored flavoring or not?

Still waiting.

This engine should give thanks....

...that I didn't throw it out the window on the way to the skatepark.

2 hours turned to 6.

I guess I should be thankful I have many engines to pull parts from.....

Start.

 Two problems right away.

One fixed.

 One caused about 2-3 more hours of work.....

 Yet another problem...

 This is the part I wish I could have used.                                                                                                This is the bottom end I used.

Surfaces clean, no cracks in the case.                                                                                                    Gasket surfaces decent.

I didn't want to switch out the shifter for mechanism but....                                                                                      Transmission looked good.

This was the problem.

I ended up breaking off a drill bit in it before I could get a chance to extract it.

Time to pull, clean, and swap a different top case......

 Gasket surfaces cut, sudzed, final clean.

 Re-installed in the new case.

 The cleaned and ready top with the ready to go bottom.

 A lot happened after this.

Food.

Skating.

Napping.

Throwing things.

Reading the manual.

Feeling helpless.

Feeling of chopped guts.

 And magically it went back together.

This was one of the biggest struggles and I have nothing to show for it.

New cam chain.

Everything is almost ready....

 New race clutch springs.

 A little more push....

 Ready for the top end.

Sometimes skateboarding isn't skateboarding.

-famous quote by Papa Puff.

Sometimes bike building isn't bike building, either.

Its all just tinkering though, right?

Weld-me table.

Size small.

Moyou is not too sure about this.

 Getting closer.

 I'm sorry for being so loud.

 One more thing.....

 Something like this?

 I'll get to you tomorrow.

 Soul saver.

O.R. organization re-attempted.

(minus) White cart

Saturday Searching.

Staying home for a change.

Pampered myself with pancakes.

 Had a lot of this going one.

Dirty...................................................................Clean

Gasket surface cleaning.

 What up stinka.

My crankshaft and clutch mechanism spring are not your playground.

 Memory game with motorcycles

Moyou inspection.

Reinstall ready?

 Nah. 

I have time.

Rust soak spokes.
