i'm familiar with this mod on the F4i, for those who dont know, you redirect the crankcase vent hose to two other hoses that enter the head and out the exhaust. You do this to prevent hydrolock and the vacuum helps crankcase pressure.

my question is, is there a hose on the F3 that i can reroute my vent hose to?

The next portion of my question involves the PAIR valve removal, so i can remove the ram air setup, ive searched, but once again cant find anything pertaining to the F2/F3.

 

why would you want to remove the ramair?

 

because from every review Ive ever read, it says nothing but good about the ram air. I have rode in some seriuse rain and never had a "hydro lock" issue, unless you take your bike places I sure dont, i cant imagine you having issues

 

i shouldve ellaborated. this is on my stunt bike. i have no need for the ram air. as for the hydro lock, its from oil, not water. if the bike is on its side, the crankcase vent hose has a high chance of shooting oil out, and it goes right into the airbox, possibly locking the engine up.

i have a 97 thats titled and ridden everyday, and i wouldnt dare do any of these changes to her.

 

I was scratching my head about this yesterday when I read this yesterday too.... lol

Makes sense now. Sorry I can't be of any help with this mod though.. heh

 

lol its ok. yes, when the bike is near balance point the engine has a good chance of spewing oil out of the crankcase breather (i overfill a little, intentionally)

on bikes where this mod is applicable, that hose is routed to the exhaust, that way there is still a vaccuum source, and should oil start shooting out, it is burned by the exhaust. it seems there is no place on the f3s to route the incoming oil to

 

Hey Man U ever figure anything out on the clean air mod for a f3 it’s hard findin Any stunt info on these dinos haha
