Crankcase evacuation valve

[Colorado700R]

Kenny, I've read about your valve for the crankcase pressure on the "other" forum.  Can you explain it's operation, and effects on performance?

You have any pictures?

I have purchased this and ran it on the dyno to test it out and it gave 1-1.5 hp. It will keep your engine running better overall and releases the pressure from inside the crank case (creating a vaccum). IMO this is one of the most inexpensive mods that really help out all around. Better ring seal, smooths out the power curve,keeps oil cleaner  Great buy

When you say smooths out the power curve, are you refering to the over rev (+6800 RPM) ??

Also do you have the before and after Dyno read-outs available to post?

It is smoother all the way thru the power bend... I don't have before and after but when my bike was being dynoed I forgot to put it on and it gave my +1.5hp peak when installed

do you have a pic of it installed

Here ya go and the new fueltatv intake, damn the fucker can suck

It doesn't necessarily release pressure from the crankcase, the crankcase vent line from the factory does that. This is a check valve installed in the factory vent line that prevents the crankcase from taking air back in on the compression stroke. It creates a negative pressure in the crankcase that apparently aids in ring seal. I bought one but haven't installed it yet.

I won't pretend to be an expert though. Kenny can give a much better explanation.

Well install it and then compare and see how much more air pressure comes out first

so you can you hook it up inside the airbox..

Is your point that it seems like more air is coming out?

  You guys have done quite a nice job! Not much I can add, except that I have already found people trying to do knock offs (that fail EVERY time). These things will pay for themselves with fuel savings alone. :grin_nod:

PM me a qoute for both models please, and can you post picks for everyone to see?

Thanks,

Kenny is like Willy Wonka....if he makes it....you pretty much want it, lol

  Here are the pics. I'll stick with my previous intro prices of $70+$5 sh for the inline version and $130+$5 sh for the cam cover version. Get 'em while you can because I'll be raising the prices $15 for each version :grin_nod:
