Strada 1000 Airbox

[RogerW]

Thanks for adding me to the group,.
I've recently got hold of a 1994 Strada 1000, tatty and neglected, but original, and I'd like to remove the air filter box and use K&N style filters instead.  I know this has been discussed before, but looking for advice about crankcase venting.
I'm planning on leaving the large hose from the (new) breather valve to the top frame rail, and also the two short hoses from the cross frame rail to the cylinder heads. 
That leaves the vent hose from the top frame rail, which currently runs to the air box housing, then down past the gearbox to atmosphere.  I presume that suction from the carbs draws oil vapour down into the air box, but if I re-direct this hose to a catch point somewhere, how much oil can I expect here?
I have replaced piston rings, bores look good, valve guide clearance just about OK I think. Any advice very welcome.

Welcome, I had an SP3 which is same bike cept fairing. Just run that hose behind starter to under bike. No oil comes out just crank pressure.
Torque heads to 35ftlbs not 32. That changed with that motor called New World motor.

welcome.

I stopped using K&N ages ago, strongly recommend UNI foam filters, the largest you can fit.

And yes, i do have a flow bench to back up my choice :)

Disagree also on direct venting. first, the original ball type one way valve is a well known agricultural malfunctioning item. I use reed type one way valves.

second step, from there i route the air to a 1 liter oil separator and only then feed the outlet of the separator into the UNI filters.

Nobody has to agree with me, but my guzzis are always devoid of any oily sweat, so works for me.

I have Mallossi's on my Cal2, Plastic cone shaped foam filter. Have replaced their foam w/Uni foam, cause of deterioration of their foam. My frame still works good on separating oil so no drippege and a new check ball. So no need for the catch bottle.

Depending on where that bike has been sitting and how long it has been sitting the frame may be full of rust. A friend of mine had a late model LeMans with the same breather system and that bike had also been sitting for a long time too. After he got it going he noticed at the first oil change that there was a lot of metal crud in the pan and after more investigation he determined that the interior frame had quite a bit of rust so he went with the old breather box system and that solved the problem of the crud in the pan.
