It wont fit.

His motor is one big nut and the breather is 2 allen keys.

you can make ya own, drill a hole in it tap a thread into it and put a air compressor hose fitting in it and place a piece of tube on it and lock it down with a hose clamp. A guy on miniriders used to make them not sure if he is still on here. Anyways they are more for the bling rather than performance as your motor wouldn't need it, doesn't produce enough power to justify to have one.

That's exactly what I said lol they are a waste of money.

 

[Divy]

why are they a waste of money sidney? i have one it was only $30

..hahahaha..first time I agree with you

 

[Sidney]

divy I think paying $30 for something that does just about nothing besides look good is a bit of a waste.

 

[Divy]

so you wouldnt pay $30 for a hair cut or something because it dosnt do anything its only for looks?

 

[Sidney]

lol thats totally different!!!

i pay $10 lol

If you could somehow tap it into your exhaust it would help power by putting a vaccum in the crank case that can be a noticeable gain in torque. The exhaust flowing by pulls the air from the crankcase.

I did this on my street bike and could feel a difference especially on low end.

You wouldn't have to tap into the valve cover tho that is kinda just for looks there is a crankcase vent hose on the motor already.

 

[Sidney]

would these things actually increase performance whatsoever?

 

[revditup]

My opinion.... NO WAY

 

[lilaidstamx]

where is the crankcase vent hose?

 

[Divy]

its at the back of the engine just look under your bike at the back of the engine and you'll see a black hose thats the vent hose

There not worth it u stack ur bike and oil goes hose and small amounts of oil get stuck in the hose under the seat, dirt and dust end up in the hose aswell, mixes with the oil and ends up finding its way back down the hose back into the motor.

 

[Divy]

ive never had a problem with oil or dirt getting into mine
i have a petrol cap breather at the end of the hose to stop the dirt getting in
