worth doing is there any performance gains?
was looking at this one that classic honda 50s sell for my 88 racehead

Im in the same boat! Planning on getting a AHP Breather Kit as well!

I think for how cheap they are its worth it...I know Ill be getting one

 

[crf50 2008]

have you seen any guys up your way running them?
yea for the price i think might aswell its only if its the wrong thing to do and ends up being a bad thing?

lets out pressure , so apparently lets things move quicker/easier .

would be most effective on big bore engines.

ca shing! job done
Pretty easy i did to 1 0f my 5-o billet covers

yep can be done pretty cheap.
ya just need to buy a brass fitting and a tap of the same thread. drill, tap loctite it in and there you have it..

not as pretty but does the same job... done it a few times myself

guess the question is can you feel any difference or sound any different, rev harder etc etc? keep the motor fresher for longer? whats the benefits? willl it be quicker

 

[sean01]

its not a performance upgrade...(well is but isnt)
wont sound any different
rev harder - spose to but i dont believe that for a second

there mainly used in race engines to vent air into the head, these engines dont have alot of drain back for oil and when you do the oil pump mod your allowing more oil to get to the cam area.
so more oil means it stays up top longer and actually pretty much gets stuck up there, by adding the breather it helps the oil drain...
not to mention the more oil up the top the less in the gearbox

much like filling a bottle with water and turning it up side down with the cap removed.. it will empty slowly.. now poke a hole in the top of the bottle(actually the bottom).. it will drain faster...

its a theory and i have no idea if it 100% needed... but hey it looks cool lol

thanks sean good info just what i was looking for

What does the line running from the breather connect to? I saw Sagone had it to like an air filter...do you have a secondary air filter for it?

 

[sean01]

you can run it to just a filter like saga has or to a catch can with filter.

i suggest using a catch can with filter because water will get caught in the catch can instead of going straight into the filter and into the engine
