crank case vent mod on an 05...elecricaly setup kleen air system...

ok people....i have a slight problem here...well you see the kleen air system on the 04-05 is an electrical one...on the 00-03 it was a vaccum based system...but now its electrical...now i don't know whether it sends a signal to the ecu or what...

i need to do the crank case vent mod....i've figured everything out....the procedure....

but the only problem now that i have is how do i ditch the electrical system...

have any of you 04-05 owners done this mod....

if yes how....

and is there no other way then a hit and trial method....

waitin....

thats it...lolz....won't it do anything to the performance.....i've seen in various instances on this board and other that the ECU's a bitch.....do anything and it'll limit the performance....like limp mode.....

if its that easy i'll do it.....


by the way if i connect the main kleen air hose coming from the airbox to the crank case vent hose then what.....like if i keep the electrical air switching valve intact....then what can be the effect.....

I recomend blocking off the air injection and seperating the crankcase vent from the airbox.

Cut the large crankcase vent hose near the airbox and plug it. Then rotate the hose from the crankcase forward. and put a k&n crankcase vent filter on the hose. now when theres ramair pressure in the airbox it doesnt stop the positive pressure in the crankcase from escapeing thru the reed valves. otherwise crankcase pressure has to try and overcome ramair pressure to get into the airbox.
The small amount of suction the header induces behind the exhaust valves will scavenge the cylinders better if air isnt alowed in thru the exhaust air injection port and it has to pull more exhaust out. You can actually get more hp from the added scavenging effect.
The negative pressure the header induces is not even close to being a high enough vacuum in either volume or negative pressure to even begin to scavenge the crankcase.
So I recomend just seperating the two and blocking off the air ports with blockoffs or plug the two inlets to the valve cover.

Well thought out Y2K! Originally I did the Crank Case Vacuum Mod then I hooked everything bak up. Then I blocked off the Clean Air holes and will use the small FIlter for the crank case vent! I never thought about the airbox pressure!

My 12R seen 4Hp on a back to back dyno pull on the same day within 15 minutes from the crankcase mod. That was with 3 pulls to be sure if what we were seeing was actually what we were seeing. May not do the same for you but it did help my sheeet out a bit. I was surprised it did that much myself as was my dyno guy.

I dyno tested the Exhaust suction reed valves VS. allowing the crankcase to vent to "open air" back to back.

I gained 2 h.p. from 4000 all the way to the limiter with the case being evacuated by the reed's.

Could you please explain your vent setup. Is this the standard cfg everyone has been doing?

Thanks,

I also saw a few more HP with the Vacuum Mod. Now that I have the Heavy NOS, I do not want to increase the EGT which the Kelln Air System will do. But I did not think of the air Box Pressure the CC was venting into!

Guys;

I Just took the case vent hose and connected it to the input of the Rubber, foam lined tube on top of the valve cover. I had to resource a fitting or two AND.....This is very important!!....

You will need to use a hose that is re-enforced. My first set up collapsed on the dyno at high RPM from the suction!

Of course you will have to plug the CC vent tube hole in the Frame/Airbox.

Remember if your bike is ever Dynoed with a Sniffer, disconnect the tube from the Case Vent and Plug the Tube to the Kleen Air System. It will make you look leaner than you are and mess up the tuning!

got it...thanks....that would surely help coz here i am going to tune it up using a sniffer.....a professional one....so if i use a sniffer with the block off plates will that be ok....

ok now one of them members of 12r.org is saying that the fi light is in when the air valve is just disconnected....this is bad....will have to figure something else out now......

As stated on the other site, with just the white electrical plug un-hooked the FI light came on...I'm going to call Muzzy's on Monday to place an order and will see what they know, but I'm going to be back out on the road w/out internet access for the week.......So you won't here back from me rite away.......Mike

we been unplugging the connector, and using the muzzy plates.
the fi light never comes on.... on my 14 anyway.

the 14 kleen air system does not involve the crankcase vent though, th cc vent is seperate plumbing on the 14

I've got the plates, but did not install them yet...Wanted to see what would happen with that bastid unplugged !!! How similar do you think the two systems might be ??? I lack a plug for the airbox at the moment and just ordered the crankcase breather filter today...My bike is down with a broken rearset, so any kind of test ride is out, I was just hopeing to get a start on the project today.......

Yours seems to be diff. from the 14, so the 12 guys would know better.
If they say you can gain 2 hp be tiing the vent in with the reeds...

I wouldn't leave 1/2 a HP on the table... but I'm a greedy horsepower monger, a horse theif I guess.
LOL.

I read a lot about the bike running cooler and the back fire w/after market pipe (which I get once in a while) going away when the Kleen is removed...I like the thought of the bike not being choked down with that thing...

Also, I'm not finding a crankcase breather line...

The Kleen unit in my above pic is missing the "small" line that gets plugged off on older bikes...It only has a "big" line to the airbox and the "T" to the reeds...Hopefully when I call Muzzy on Monday they can help..

That is the same as the 14 then!
Install the plates, and plug the hose into the frame/ airbox.
