I am on ebay trying to find out fair prices and I found this.


General Discussion what do you think of it.

 

Wow, for my dollar you better REALLY desire no wheel skip to buy that. It is pretty much on par with what they go for other bikes.

 

check with yoyodyne.
that one is located in eastern Europe!

 

I am running a Krankvent (creates partial vacuum in sump) and my bike has surprisingly little engine braking, despite running 12.2:1 compression and a lightened flywheel..... I may someday get around to putting together the vacuum-relief system I thought up, another step in this direction, all for far less money than the slipper clutch......

 

that or learn to downshift!

 

true dat.... but I don't ride the track with my VTR, so it's not a big concern for me at the moment (and, as noted earlier, the Krankvent does an amazing job in preventing lock-ups).....

 

Now I am not condoning or condemning these products just found them on ebay.
Plus now I get to lean something. "the Krankvent does an amazing job" Please explain I did a quick Google and there is some stuff on there that I will check out.


Now here are two more things I found interesting Mod on intake

Again what do you guys think of these

 

the Krankvent is essentially a one-way valve that one connects to the vent lines coming off the valve covers. Its low pressure threshold works to create a partial vacuum in the engine sump. This is supposed to help reduce pumping loss (FYI, Ducati uses a mechanical pump to create the same conditions on the new Panigale, F1 cars also use similar tech). One added side-effect of the KV is that it reduces compression braking.......

 

Thanks for the info mikstr I went on google last night and found out some info on it. What brand did you use got any pics of it. I am in the middle of an engine build right now might do this along with all the rest.


Plus what do you guys think of the rotors above.

 

I bought the Krankvent (note spelling, it's the brand name)...

 

So its like a PCV valve in car engines?

 

in principle, yes, but far more effective.....

 

Im not saying it does not.. but Im not seeing how.

Compression braking comes from the dynamic compression in the cylinder...ABOVE the piston rings.

What does a positive crank case vent valve , venting pressure (negative and positive) BELOW the pistons have to do with compression braking?

 

it reduces pumping losses (a major source of parasitic loss on a four-stroke), thereby letting the engine turn over more easily..... I had read about this before and can attest that my VTR has relatively little compression braking, remarkable considering its compression ratio is almost 3 points up from stock..... Bear in mind, too, that my engine has significantly reduced spinning weight too (flywheel, crank, clutch plates), not to mention magnesium wheels, all things which should contribute to GREATER compression braking

 

OK, got it, so really it is an associated thing,, not a change to the cylinder compression (compression braking)

I've never heard anyone refer to crank case pressure (or lack there of from a crank case vent) as related to engine braking till you posted it.

It's not mentioned on manufactures web site I can find at all as a feature, a byproduct or in any way.

Yes I understand if a vacuum is applied (and timed correctly)to the crank case, better ring seal, less pump loss, ect is possible... Just never heard anyone try and tie that to engine braking.

Thanks

Thus ends the thread Jack... Perhaps start a thread in tech on your install, use, perceived value and results

 

Last word on the vacuum end of things: do a search on the NAG valve (http://www.jauce.com/auction/j280151188), it's what got me going down this path.....

 

I have not installed my new engine yet but I think that even with a stock engine if you lightened the flywheel that it would tend not to wheel hop in with the rear just from the loss of flywheel mass

 

After I installed a lightened flywheel on my stock engine, I skid the rear wheel a couple times while getting used to the new feel of rev matching. The flywheel lightens up the mass of the moving parts of the engine, but not all of it.

Good to see you posting again!
