Msambuco,
Thank you for the response. It was me that did the top end. I guess that I will need to look into how to re-align the shafts.

Who did the top end? You or a shop? In either case something is assembled wrong. Most likely would not require removal of the cylinder bot you will need to re assemble power valve assembly. While they look complex they are really simple to do.

Technical / no power valves on 2000 cr250

A top end was done on my 2000 cr250. Now the power valves do not operate. I took the cover off and I am unable to rotate the valve drive shaft when gripped with a pliers. I am thinking that the valve drive shaft was mis-aligned with the pinion shaft when I replaced the cylinder. Am I able to correct this without lifting or removing the cylinder?
thank you
Gil

Well, I offered $500 for both the YX 125 and XR 80... I've not heard a word as a response...  I'm assuming they think it's worth more than I'm willing to pay...  so the search continues...

As usual, I can't just leave anything plain....  So I took some leftover paint and stain to the bike bench.  Also as you can see, it works fine for larger bikes too...  Can ya tell I ride orange...   :o

This issue is, when you get the cruiser that high, you can really see just how dirty it is... looks like I'm going to be busy polishing lots of chrome and paint...  also I realized just how little tread was left on the rear tire...  :-\  One thing I did try while the KTM was on the lift, was to use a small auto scissor jack to lift the rear of the bike.  This would allow me (when needed) to remove pull the rear tire.  It worked great, next will be to try it on the cruiser as well.  I don't see any reason why it wouldn't work. 

I did try to use the pulley system I had rigged up to pull and store the stand up next to the ceiling of my garage.... FAIL!!  it's heavier than I thought...  need to go to plan B, as soon as I figure out what that is...

I've always wanted a bike work bench...  the issue is my garage floor space is limited, so I didn't want something when not in use to be taking up valuable space.  But... my garage also has 12ft ceilings.  I started looking for something cheap (yes I'm cheap) that when not in use could be stored near the ceiling via a pulley system.  After searching the interwebs, I found a video of a home made stand, that utilizes a motorcycle jack, and auto jack stands.


Here's a link to the video https://www.youtube.com/watch?v=Jz8oFhyBrhk.  I took his idea and made a few changes and built the following work table.  It's made from 2x10 lumber with a 3/4 plywood top.  The cutout is designed so the bike lift will fit under the stand, as this is how you lift and move the stand. I also had to build and figure out a way to mount a ramp.  Most of the material used I had lying around, including the front wheel stop. I used a door hinge so it can fold down when not being used.   
Pic 1 - shows the 1st time I lifted the stand and dropped in onto the jack stands.  I was surprised as to how stable it was.
Pic 3 - I bent a small piece of steel and attached to the plywood ramp, with a bolt going through the plywood to keep it from falling. Yes there's a support under the plywood ramp for stability.
Pic 4 - the 1st trial on putting my bike onto the table... this was just prior lifting it with the jack
Pic 7 - loaded and lifted to it lowest height.  I can go higher, just need to lift and adjust the jack stands.

So far so good...  I really haven't used it much yet, as I just completed it... but with the bike loaded and sitting on the jack, its surprisingly easy to move  around the garage.  The next test will be to load the street bike...  That will happen this weekend.  And finally the test of the pulleys to lift it up to the ceiling.
