Block-off plates for your C-10 (SEE LAST POST)
« on: May 12, 2011, 05:38:22 am »
Tired of the top of your valve cover looking like a junk yard of spare parts?  I can help.  I have been making some block-off plates that takes the place of the exhaust emissions (reed valves) that sit on top of the valve cover.
They are are $20  for a set (plus screws) or $25 for a plug and play kit.  The kit includes 4 SS button head screws, rubber caps for the vacuum ports, and a plug for the air-box.  Plates are powder coated to the color of your choice.
You can get in touch with me at lilliefabrication at gmail dot com, or leave me a message here. 

You can go from your stock factory set-up to this:


I can coat the plates to just about any color you desire.  Here are a few samples of what I do have on hand:

I also have a Candy Persimmons red.
Thanks for looking...

Black would be fine - unless you have LIME GREEN.  I restoring my dad's bike and it will be painted the same color as the ZRXs.  Full kit please.  Where do I send the payment?  You can email me at fhunt at pwcgov dot org.  I think I bought a used JCW case form you if I remember correctly.

Maybe a silly question as I am not very familiar with these engines yet but, what do you do for cranc case ventilation when you do this?

Nothing.... This does not alter the crank vent which is just over the transmission area. Removing the reed valves only removes a passive emissions system that allowed fresh air to enter the exhaust tract and water down (pun) the unburnt hydrocarbons thus making the emissions appear lower.

Is there any performance improvement, or is this just a cosmetic mod?

More of a "makes service easier" mod than anything else. Performance improvement if any would be minuscule. Makes removing the valve cover a lot easier as the air valve assy must be removed beforehand

Thanks, I had not looked into that.

I got the plates on the night before last.  Started T-Cro's coils last night - only had a few minutes.  Had to cut part of the OEM watershield/seal off so the coils could fit in the sparkplug hole.  I put dielectric grease on everything.  They felt like they snapped on nice and tight.  The coolant hoses are next.  Then I'll run the wires for the coils.  Thermo is already rebuilt.  I think the hardest thing to do with the block-off kit was to get that screw-in plug for the airbox started.

Thanks go to both of you for your products!

Looking good.  What did you use to paint the valve cover?

Scrubbed it clean, wiped with acetone, then aerosol can of 500d engine paint picked up at AutoZone (can't remember the brand.  Says its fuel "resistant".  I've used paint from Tractor Supply that said it was fuel resistant and it worked great for the life of the item, but the nearest one to me is about 40 miles.
