Weird Plastic Shit

So when I took out the camshaft cover yesterday, I failed to mention that a couple of plastic bits fell out. I was scared shitless because I thought I may have tapped the cover too hard and snapped something. But after taking apart the entire top end of the engine, it seems like they don't even belong to the engine at all.... at least not to the top half where it fell out.

If anyone knows what this is, PLEASE tell me

Anyways, I had my buddy over to help me take the cylinder head off. Man those 10 screws are torqued TIGHT. Whenever I tried to turn it, the whole engine, proped up on wooden boards, would turn with it... and believe me, without a second pair of hands, its difficult to stop it from doing that.

My more fair-skinned second pair of hands

After taking the screws holding the cylinder head to the cylinder, the entire top half of the engine just kinda pulls out with a few taps of the hammer.

Cylinder head off ...

BAM!

Cylinders off...

BOOM!

Got my bore kit, my cylinders, and I'm ready for the machine shop :)

So much for my tidy garage

The cold must be getting to me

Christmas day, -17 with windchill; perfect day for a ride don't you think? Yes ladies and gentlement, I'm still out and about. An old columbia 3/4 length coat, jeans, and lots of thermal liners keep the ride bearable but I'm starting to look for some proper winter riding gear - maybe some touring stuff with good armor.

ZX7: "Brrrrr... store me away already jackass!"

Nothing destroys personal projects quite like the holiday season. All the christmas cheer was just too much for my senses. Over the past few days I've been cleaning my engine blocks a bit in preperation for removing the cylinders for boring.

I started off by removing the camshaft cover and wrapping it up

I've seen engine tops in pictures so many times but it looks a lot cooler in person

Now, here is where I seriously screw up. I don't know exactly what came over me but instead of loosening the bolts that hold the camshafts in I tigthen them... quite a bit before realizing what I've been doing. So now I suspect that at the very least the bolts are jacked. I just hope the threads themselves are okay *crosses fingers*. Anyways, I eventually realize that a boob I am and start loosening things.

The camshaft holders eventually come out ...

and everything gets neatly wrapped

Now all that stands in my way and the cylinder block is 10 bolts holding the cylinder head in.

The power of Pine Sol

While I wait for Pine Sol to work, my neighbour brings over his 2005 Ninja 250 for winterization.

The legendary EX250

My first bike was a 2009 EX250R so I have a soft spot for the little 250cc machines. This was my first time workingn on the older ones and my neighbour was kind enough to let me ride his bike around the block. The 2005 EX250R was a little more powerful than my stock 2009 EX250R but was much weaker than my 2009 after it's carb needles were shimmed. *sigh* I miss my 250

I return to the carbs

The Pine Sol cleaning came out with mixed results. My 4 part Pine Sol and 1 part tap water solution had some positives and negatives. Lets start with the positives.

For starters, the gunky parts came out pretty much spotless

... and after (from a different angle)

Now for the not so good. To begin, it looks like the Pine Sol took off the finish on most of the screws and bolts. I suppose if I were to do this again, any finished parts need either a much weaker solution or less soaking time.

Another not so good thing is that I noticed some white residue on some surfaces. Not sure how serious this is. I plan to disassemble the carbs again and take a rotary tool to it, probably with a buffing or abrassive tip.

The white crap even stuck to the inside of the cups ...

... and my hands!

Lastly, it appears some of the REALLY tough stains didn't give up the ghost.

Some crud comes off with a bit of rubbing ...

... but Pine Sol is no match for the REAL tough shit

For a $2 cleaner, Pine Sol did great but a tad more work with a rotary tool will do wonders, I'm sure. Some more pics:

All dried up and ready for assembly

One carb at a time

Sexy holes; carbs are full of em

A little grease helps make a better seal

For screws too!

Done!

I'm gonna really focus on cleaning up these carbs. Partly because I want good control over properly atomized fuel but partly because I want to explore potential problems before I start working on any other parts. Come to think of it, the carbs really should have been the LAST parts I tried to clean. Oh well. Onwards and upwards!

Fun with Carburetors

Nothing like tearing into my bike after a long business trip! I read a forum posting while I was on the road about cleaning carburetors. The posting had several postings hailing Pine Sol as one of the greatest carb cleaners of ALL TIME.

Nasty stuff

Oh look ma, more gunk!

The idea of a cheap, effective, and deliciously scented carb cleaner tickled my fancy. So down I went to Canadian Tire on a mission to buy two bottles of the stuff... but they were on sale so I bought four.

I rummaged through all the crap I've taken off the bike and find the clunky Keihn. DAMN these things are heavy. Starting from the right (while sitting on the bike) I undo the first set of float bowl screws.

So clean you could... put fuel in it

Mostly clean save for some fuel stains

More fuel stains. Think Pine Sol can move this stuff?

Not a terribly relevant picture, but I like the focus of the shot

It was a good thing I bought four bottles of Pine Sol because I had to top it off with a bottle of water to submerge the whole carburetor.

In it goes

As the carbs came apart, I put the various pieces in little cups. Four ups for four carburetors and a fifth cup for misc. parts.

Can't wait to see how they turn out
