Compression Release Modification

[dave916]

with standard tank etc dont think it can get much  easier the pushing a button that reset itself at your left knee
my view is with cable/ lever it is just more thing to go wrong  or even people holding lever while starting engine

Do you really want to be feeling around for a decompression button at your left knee if you stall on a nasty hill climb, etc.

q If you think it worth the hassle and cost of cable, lever and some kind of mechanism to push the button go for it
all i am saying is due to the position of this valve it cant get much easier

one GOOD kick can be hard to get done after a long hard full day of riding!!!!

If I'm on a nasty hill, and have stalled it, who cares, I'm going to point it down, in second gear I'll bump start it. now if your talking about a hill that you MAY be able to continue on after you get it started that would be a different story, although even then I would ask how you did it before the compression release. The compression release is a great idea, primarily when the bike is cold, after that usually one good kick and its running.

I'm thinking more of a long gnarly single track hill climb with rocks and roots, not a short open blast of a climb. Something where you can't easily turn around and is to awkward to get a good kick on the 500.

This decomp you guys came up with is very clever.

YOU'RE ON A KX500!!! If you stalled it going up any hill then I don't know what to tell ya............Stalling on a hill while riding a 500 two stroke is like winning the lottery........is it possible? sure.........is it likely? not really

Hey Larry, Oscar here saying its good to meet ya.  Sending you my 98 kx500 head along with my revloc for doldguy tomorrow.....can't wait to get my head back and experience the magic I've been hearing about on this awsome forum.  Many thanks in advance.

[Purpletj]

You won't be disappointed USMC. I received mine back last week and it looks better than new.

[USMC 500]

My head and Dougs new Revloc got sent out today via fedex........they sould get out to you sometime early next week Larry.  Once again thank you in advance.

[USMC 500]

Just got my head in the mail......all I can say is............WOW!!!!  The work is excellent.  It looks as though it came from the factory with the mod done.  I can't wait to get my motor together so I can try it out.  Thanks for everything Larry.

What's turnaround time on this? Now it's nice out, I hate having the bike down for long.

 Not quite that fast, but I try to do all the heads that arrive during the week on the weekend and ship back on Monday.

Larry would it be ok to ship my mine on the 12 to do the modification?

I like the idea of having the entire assembly on the head rather than taking up room on the handlebars. I need the handlebar space for kill switch, Baja Designs headlight switch assembly, mirror and brushbashers. I do wonder if the location of the release button would work if you had a 4 Gal. Clark tank installed.

Just push the blue button to set the release. The valve automaticlly closes when the engine fires.what a awesome job,must get my kx500 done
 
Cost to modify your cylinder head is $125 plus $7 return shipping.
This includes the decompression valve, lapping the headgasket surface and abrasive blasting.
