Oil Breather On Thumpstar (Do They Work?)

[jordazbro]

Hello guys .

I have a pitbike 140cc.

I'm just wondering do oil breather do anythink.

Because i got one on ebay .Because of heard good news about these off my mates that they do work .


But i'm on here just want to ask it from you's



........Where they go.........

Well theres a pipe with a long tube for it.

You bolt it up next to the muffler.

Then you replace the old oil dip stick .

With the one they gave you.

You run the long tube. to the back up the oil breather

To the new oil dipstick and bolt it on.



....................................................

But what i want to no

Whats the hell do they do ??



Someone please help ?

basically they vent crankcase pressure... as to whether they do anything, or are of any value, you'd be better off asking one of the motard guys..

Yeh they reduce crank pressure and are 'ment' to increase HP (meh) but more so when you drop your bike oil doesn't go onto the track!

Looks to be a different part ... that link i posted replaces the tapet cover

 

[jordazbro]

Yes but it says it for a 110.

Like so that would not fit on our kinda bike the one you send across yesterday?

they reduce compresion

but the ones you are looking at dont work

the proper ones have a one way valve in them that doesn't alow oil or air back into the head the ones you have above are just for bling purpose as no crf says trick looking catch cans

for dirt riding you want the compression but if your motardin you wont get as much lock up but you have to buy a decent unit but i cant search for one atm
