Dented oil filter!

This oil filter misunderstanding happened to me years ago. A fellow, who I was working for, let me ride his bike to warm up the oil before the oil change. I was hanging out with him while he then changed the oil in his bike. When he was completing the work, I asked him if he was sure he was putting the fence on the right way. He got the manual and showed me that the fence was placed on top of the oil filter. So, I was looking like the crazy one. I then went home and retrieved my manual so I could show him that the fence was supposed to be on the bottom of the filter for my motorcycle. His bike was a KZ1100 (on top) and mine was a KZ750 (on bottom).
Just thought I would share my experience.

You had me concerned with the fence for a second.. Yeah, it goes on the bottom..though it would seem to make more sense to have it on top, then the oil could get to the filter easier..

Either way, it seems like my #2 cylinder now has absolutely no compression at all. I tried tossing some oil down the sparkplug hole too, and nothing.. either one or both of my valve(s?) are toast I think.

Is it possible to throw off timing if you tighten the cam chain too much?

I'm gonna pull my valve cover/head today and take a look..I really hope it's not a big deal.

The good thing is that 1, 3, and 4 are all perfectly within spec.

The *really* good thing is that my wife said she thinks I should get a new bike because she isn't happy I'm riding something unreliable! :woohoo:

UNRELIABLE,,,, you should go wash your mouth out with soap!!!!

if the other cyls are up on compression ,and that much metal, I am thinking a hole in the piston,, hope not

Her words, not mine! :silly:

I figured out why the #2 had no compression, and likely what happened to the oil filter.



Seems my piston didn't like being in one piece.

:blink: :blink:

The cylinder walls have 2 large gouges in them now, so it's definitely time to start weighing my options.. *sigh*

...both sides!

Thats ugly,, how bad is the cyl,, looks like it will need to go to oversize to me,,,,, big bore here we come

On that note.. can I do the one, or should I do all 4?

What are my best options, and what should I expect through the process?

Oh..and the grooves in the cylinder are bad..around .5-1mm in depth at the top.

Do all four,, and in addition you need to get the head checked,, I think you will find some metal on the valves also,, which will require a valve job on the head..

Goes from bad to worse:blush: :blush:

Well I've been speaking to APE already, so we'll see what happens.. I'm going to investigate a high-performance machinist in my area first, and then if that pans out, figure out if I want to invest in getting the engine back in order, or just part it out and find myself a nice affordable Kawi Ninja 650R.

I just wanna ride!

Bummer! I also found it odd that the "fence" was solid as I have only seen perforated ones. Then again I didn't know any ere supposed to go on top of the filter. Just when you think you seen/know it all!:woohoo:

Hey..Just bringing this puppy back up top to say - de-winterize properly, and I'm gonna be rebuilding it this year, so all design ideas can be sent along.

If I decide to bob it, or at least chop the frame back a bit, is it enough to get a welder to put a support piece between the frame just behind the suspension mounts, midway through the gussets, or should I have him do it at the back of the gussets?
