Breather hose mod, Air filter mod

kilzje · Apr 12, 2023

Hey guys, I've been looking at older threads for breather hose mods but I failed to find any pictures as these threads are quite older now. So bottom line, can someone provide some pictures/details on how to setup these mods? I'd like to see how you go about these. Also, did someone mod the air filter and switched it up for a cone filter instead of the regular one? Pictures would be best! Thanks

I just saw this and figured I’d kick it up to see if anyone responds with images and suggestions.

Carb size 650

Has anyone tried bigger carb in 650 berg? I know that some have bored fcr to 43mm, has that made noticeable difference? Or even tried bigger Mikunis, 45mm or 48mm HSR?

Thanks guys! I'll do the oil catcher mod with an air filter at the end on the forward hole. The back one will be plugged.

Dont plug the back hole .In high rpms your oil will come out from the big pressure and spoil around . Its better to connect both plugs in the oil tank for a great breath .

So connect both hoses to an oil catch can, and finish it up with an air filter at the end. Gotcha
Looking at your pictures: You have a line from the oil hole that goes somewhere up on the engine. Whats that about?

Most of the 90% of the bikes in the market have two oil fumes way out .One or more in the head and one in the cases of the crankshaft .Husa have only one way out in the head but double . This show us how much big is the pressure and the fumes is in this bike . With this hose connected from oil reffil plug to the oil catch can you can lower the fumes and the crankshaft pressure in half . this is something Husa needs a lot .All we know how much sensitive is the crankshaft in this bike . So with this you can lower the pressure in the engine and the oil temperature by 10-12 c .

Yes of course it works but the question is how effedtive it is with 100 c fumes inside to air filter after 15 minutes of operation ? Did you ever measurid the temp inside air rubber hose connection to the carb before and after ? Did you ever measurid the carb temp before and after shielded ? Did you ever measurid the temp of the gas in to the tank before and after shielded ? Did you ever measurid the rwhp when the bike is cold and after 15 minutes of operation ? Because i did it and when i seen the results done all these mods .You see always the performance was the first priority for me.I was a streetracer always and still i am.
