Post airbox removal questions

htsang07 · May 8th, 2013, 06:44 PM

Hello,

So i've removed the stock airbox and put on a K&N pod filter and jetted my carb with a Factory Pro jet kit with the help of the DIYs that i came across on this forum. As I was putting the bike back together i came across a tubes that i cant find where it belongs to; the tube is connected inbetween the 2 carburetors.

I also found a tubes that is connected to, what i think is, the "vacuum switch valve" and WAS connected to the stock airbox. I'm not sure what i'm suppose to do with this tube after i remove the stock airbox...

Thanks a lot.

check out the remove Kleen air system DIY. you will need either a block off plate or some vacuum caps for the stock plate + cap for the one T junction

as far as that one hose, if you did not disconnect anything you should not have it has to go to the gas tank somewhere as i think those are the only hoses you have to disconnect other than Kleen air system stuff which you did not remove

omg. i wasn't able to find anything searching before you told me to search for "kleen air" sorryyyyyyyyyyyy

or you can put a filter on the big hose and shoot fire out the tail pipe.

the hose from the carb is a drain tube that should go down thru a loop in the frame

If i do go on to remove the kleen air assembly, would i have to re-jet? On the DIY thread they said no but then (I think) some people hinted that it might be necessary ... Because it causes it to run richer? Our something like that? I mean, i already bought that block off plate and will most likely go through with it but just want to know what to expect

The KLEEN air system does not add any fuel to the engine or involve combustion. It is used to help pass EPA requirements. It adds a tiny amount of fresh air to the exhaust manifold so the exhaust gas does not appear to be too rich and contain too many contaminants. The system is designed to clean up the exhaust gases. Sort of a way to trick the system. It will also help eliminate the popping you get on decel. Put the block off plate on and enjoy the ride.

Thanks. I actually just got the plate in the mail just now but its raining so i can't put it in

by the way, is there a gasket that i should replace when switching to the block off plate? I couldn't find it on the parts store.

No gasket needed but you can seal it up with a good rtv or other.

***if I remember correctly***

I did not use a gasket on mine. It couldn't hurt, but I don't believe it's necessarily. After I connected and tightened everything up, I checked for leaks in the block off plate and didn't find any.

Also, you might want a 5/8th clamp-on breather for the lower part of that Kleen air delete. I believe it's in the DYI, but thought I'd mention it just in case. I purchased this for mine (was $2 free shipping when I got it haha): http://www.amazon.com/gp/product/B00...?ie=UTF8&psc=1

Hey thanks, so i guess ill just forget about the gasket since it isn't necessary and about

I;m not too sure which part you are referring to that may require a breather when removing the kleen air, from what i understood from the diy, i think the kleen air system removed had 2 tubes removed with it; one that went to the stock airbox, one that went where the block off plate will cover, and one is a vacuum hose that connects to a T-connector which will be plugged. Am i missing something? :/

I'm putting my air box back on because of the class I'm racing in and I don't have a hose on that fitting between the carbs. I'm not sure what happened to it but can I cap it off or should I find a replacement hose? You said it's a drain hose? I know about the drain hose that comes from the fuel tank.

4th picture?

yeah, you need a breather for the crank case, but not for keen air system delete. that hose is Carb overflow hose, should go down along gas tank drain hose
