I didn't mean to sound so serious.  I was mostly pouting from feeling left out.    

Hehe.  No problem, you addict. :mrgreen:

Quote from: Ed89About the valve compressor thingie:

It looks like a slick gadget, but I'm unclear about how it's applied.  An 8" C-clamp?  It sounds like you're doing this with the head removed or something.  If this gadget can help with a regular valve adjustment (after removing only the valve cover) please explain in a little more detail.

PS - I'm glad to hear that you got the bike started again!  

Thanks!  I had to fix it quickly since my car is semi-out-of-commission with a clutch disk that is in dire need of replacement.  Too busy lately.  One annoyance follows another (e.g., valve, brake pads, etc.)  I am still waiting for the Avon AV45 front tire to come into the dealer's--it's been 7 weeks! :x  What's wrong with this tire company?  So now I am riding around with a bike that is 1.5 month past its safety inspection date (didn't pass due to bad tire).

Anyway, the C-clamp is 6 inch, not 8-inch.  8-inch cost a whole lot more and I am cheap.  OK, I am semi-broke.  It is for removing the valve, not for valve clearance adjustment.  Here's how it works:

Look at the diagram (courtesy of www.bikebandit.com), after removing the shim+tappet bucket, you can see the top valve spring retainer (or spring seat), the keepers and the tip of the valve stem (or valve cotter).  Top view is like:

/---\
|(o)|
\---/

Where "o" is the tip of the valve stem, "(" and ")" are the two keepers, and the thing surrounding it is the top spring seat (valve retainer).  Now, only the valve (stem) comes in through the combustion chamber--everything else goes on top of the cylinder head.  The springs are always under compression, and is prevented from popping out by the keepers.  The keepers sort of "wedge" everything in place.

Now, to remove the valve (and everything else), you have to remove the keepers.  You do this by compressing the top spring seat (valve retainer) and the flat end of the valve, so that the valve stem sticks out through the middle and you can remove the keepers (the "=").  Here's my attempt at more stick figures (sideway since it is better that way to draw, and it is also way not in proportion):


  |------ |
-> |       =||||||---|  <- valve
  |------ |    ^springs
    ^     ^spring seat
 sch40 pipe

So you apply pressure (using the C-clamp) at the end points indicated by the arrows (-> and <-), compress the springs, and the valve stem will poke through the middle into the sch40 pipe.  Then through the little cut-off window in the sch40, you can use a pair of small pliers to remove the keepers.  Then you release the pressure and the valve is not retained anymore and you can slide it out from the combustion chamber.

So you need a biggish C-clamp, since it has to press on the top of the valve (where the shim and bucket normally are) and the flat side of the valve in the combustion chamber, and it has to accomodate the sch40 pipe thingie as well.

Thanks!

Yeah, the whole setup sliding around is the biggest problem/danger.  My double-sided mounting tape did the trick for me this time.  Since you will probably be using the clamps a lot, good idea to tack weld them on.  Safer and easier to use.  I read a website that also has another idea for the pipe thingie:  Cut a section of a steel pipe about the same dimension (1 inch OD, 1.5-2 inches long), then instead of cutting a window, just cut off a 90-120 degree section lengthwise of the pipe, so it looks like a 3-dimensional "C", and tack weld it to the clamp.

Thanks for the offer of the rotors!  I thought they were long gone already because there was some mention of Srinath coming over to pick them up some months ago.  If Kerry's giving his to me, then I guess you can keep them for Srinath (if he ever come around and stop messing around with his GS "enhancements" :mrgreen:).  Otherwise I'll be very grateful if you can send me one.  I must have the thinnest measured rotor on this board.

Cheers,

Oh yeah, to drag it more OT, here's the bent valve:


It is just very slightly bent.  The groove near the tip of the valve is where the keepers mate to.  And from the pix of the un-centered valve:

It is clear that the bend of the IN valve is away from the EX valve, so indicating that most likely the EX valve hit it.  If it had been hit by the cylinder head, the bend would be the other direction, no?  Look, Suzuki has so helpfully labeled the intake valve with "IN", so that I won't accidentally put it in the wrong valve opening.

Yes, my desk is messy with the beer can and all that.  What you don't see is the rest of my bedroom there: desk, folded up futon bed, clothe rack, assorted tools, disassembled shipping crate for my motorcycle, AND my disassembled motorcycle (the whole shebang).  All in the 10x12 room.  I was very happy when I got the bike fixed and pushed out of the room.  And so much for the "stainless steel" ruler.

Cheers,
e.

P.S.  To make this thread completely out of topic, here's a photo of a Taiwanese dish:

Quote from: dgyverThis is probably some info worthy of putting in the FAQ forum. I can take some pics and do a write-up as well of what I made.

Please do!  I'd be happy to "submit" it for you.

I have a head that I need to take apart to get it milled. I will take some pics as I do it. I never really think about taking pics as I work on stuff unless I may not remember how to put it back together. It looks like it may be raining this weekend so it may be a good time to do it. The valves need to be necked as well so I will get some pics and measurement of this as well. Actually this documentation of work has been a benefit to myself as well due to short term memory loss.

He came by one day at work but I thought he was going to come to my house. I did not have the rotors with me, so I still have them. Since he is not travelling as much, not sure when he will be coming this way again. Just let me know if you need one.
