i gotta change my plugs...i think i'll do this also.

good write up man.

Why direct PCV hose to your exhaust instead of leaving it alone? The PCV hose is routed to the airbox so that the hydrocarbons from piston ring "blow by" can be burnt through the induction system. By choosing to run your PCV this way, when the reed valves are closed you have NO crankcase ventilation at all. And, by venting any type of air/gas into the exhaust, your defeating the purpose of this modification.




How dude? Explain it to me....... I'm a penis. Most bikes are subject to catastrophic engine failure from loooong wheelies due to the simple fact that oil cant return to the sump in the oil pan, because the engine is at an angle that it wasnt intended to run at (90 degrees). :dunno:

actually, im wondering the same thing. why not just leave the CC vent alone. and just cap off the T at the valves.

any reason/problems in doing that?

im a bit concerned..about CC pressure/fumes building up. asking for problems...

im in the process of doing this now..hopefully someone chimes in and tells me yay or nay...

ok, its finished. i didnt do anything with the crankcase breather. hooked it back up how it was. it NEEDS to be there.

time to go for a test ride.

 

[nevada]

ok, so i did mine just a bit different. instead of using a T. i just ran a short hose between each valve. plugged the to vac ports, and the port on the air box. leaving the crankcase vented how it was. the crank REALLY needs to be vented.

so far so good. the exhaust sounds a bit...smoother... not sure exactly how to describe. but there was a difference. and the idle seemed smoother. and i also had to adjust the idle slightly.

BUT, on my trip yesterday, i noticed my left sleeve was unsnapped. so i sped up to gain some speed,and pulled the clutch. took my right hand, and reached over to snap it. once i got back on the throttle...nothing happened. it had died! wtf. thats NEVER happened before.

released the clutch, it started right up. so i did it again. let go of the throttle, with the clutch in. and watched the tach drop...fluttered around 900-1000, then just dropped off, and died. hit the starter, and it fired right up.

never did it before that, and never since. :dunno: weird

What RPM did you set your idle, nevada?

1300, or as close as i could get.

When you do the version of this mod. that Nicky posted you are NOT removing the crankcase vent. You are simply rerouting it. In fact the idea here, is that by routing to the PAIR valves you are able to create a slight vacuum in the crankcase. Read below. I have personally been running this method of KLEEN mod. for the last 6k +, w/o any problems.

um, no, by doing it the above way, there is NO longer a crankcase vent. all youve done is connect the top end, to the bottom end. theres NO where for the pressure to go.

The crankcase is no longer vented to the airbox. The vent is now routed to the PAIR valves.

Dude, I'm not gonna argue w/you about this. I explained it as best I could. I refrenced xtremewlr's thread, and quoted what he said about it. I couldn't find the other two threads that I had read about this, though. This method of the Kleen mod. has been around for a loooong time. It was also being done like this on the 03-04 model. I've been running it for about 6k. I've never seen, or heard of any problem(s) w/it. That's basically it. The proof is in the pudding...

no argument man..
but look at it. what do you have. where are the pair valves located? in the valve cover, right?
once you remove the vac lines from the valves..they do NOTHING? correct?

if you take a hose from the crankcase, and route it to the pair valve, what are u doing?
connecting the valve cover, to the cranks case.
they are ALREADY connected internally. now, with the KLEEN done this way, its a big loop, a CLOSED system.

im not disputing that its done that way. im just saying its not a good idea. i also dont see that it would gain ANYTHING. and can only see that it could cause problems.

Is there any reason why you wouldnt be able to just leave the catch bottle hooked up to the air box instead of plugging it at the air box??

mines still there......

 

[nevada]

your wrong, the pair valves DONT go into the valve train, thats why its illegal to do it in supersport! the pair valves lead into the exhaust. so its NOT a closed system, the crank now breaths into the exhaust and if u were to have a problem all the crank oil would go into the exhaust and on the track (BAD). but with it stock and going to the air box at least some of it will get burned up in the combustion chamber before it enters the exhaust and gets on the track!! and YES IT DOES GAIN POWER because your putting a vacuum on the pistons, the pistons get pulled down on a down stroke and yes all good for the motor.

stunting, street riding your all goood on power and wheelies, but drag and road racers if they have a motor prob officals dont want a direct line for oil to shooot out of the crank into the exhaust and onto the track, END OF STORY

interesting. i did not know that.

so its still better to leave it connected to the airbox.

 

[nevada]

my opinion better to re-route!! u gain a horse or so, ur bike breaths better, u can do wheelies to ur hearts content, and really!! how many people u no that there bottom end just explodes and oil blasts out of everywhere up the crank hose and into the air box making so much white smoke ur head would explode??? thats right it doesnt happen!! UNLESS u spend 20k and do crank, rods, pistons, head gasket, cams, milling, valves ect running 17k RPM, 140rwhp, or turbo or nitrous

the fraction of a HP that i might gain doesnt interest me in the slightest.

i like it just fine as it is.

 

[nevada]

before it enters the exhaust and gets on the track!! and YES IT DOES GAIN POWER because your putting a vacuum on the pistons, the pistons get pulled down on a down stroke and yes all good for the motor.

you realise that same vacuum is applied to the piston as it travels up too, right? negating any gain you might have had.
