a few questions i have that searching and reading did not answer on my 07 250x.
last year i put almost a 100 hours on my 12f ( bought with 43) ski ran flawless all year. read and searched for the last week and have not found to much up to date info on the things i am in question below.
so given the amount i plan to ride this year, here are my questions.
this is what i am going to be doing already, wet pump mod, and 300x spec pump bearings, shaft etc. also considering flat filter, and doing 2nd water box delete as i did it to my 12f with a u pipe and it was very easy ( how much different to do on the 250x?)
These are the topics i am still unclear about, what are the pros of cons now that people got some time on these mods.
BOV block off - eliminate boost from fluctuating?
Emissions block off- accurate egt/ a/f readings? as well as running motor cooler?
GIO- i have a fresh oil change and is reading accurately, but looked at a 17 hour ski for my buddy and the oil was FULL of fuel and milky, smelled like gas... now i am a little worried due to the amount i ride and the cost it would take to constantly change the oil and filter if i do have the issue.
so i read about altering the catch can with the ocms system but its not produced anymore nor have i been able to find updated info other than this. http://www.teammotoracing.com/?cat=79.
i dont really know anyone who welds aluminum is there another way to prevent oil and gas mixing?
thanks in advance and please keep this on topic, i dont want to hear search, etc etc. i have and still need some input.

The BOV have the tendency to leak and reduce boost psi

also i see alot of 1 degree pump wedges cant seem to find a 2 degree. is there a bigger increase with the 2* wedge vs 1* or are they similar?

Flat Filter: Does sound cool but creates place for water intrusion (albeit less than with other modded air intake systems). I'm not convinced it adds mph but I ride in cool ambient air.

I do my own cans ,( always have been for my customers )
if you dont have the tools at hand
Take your catch can to a machine shop
Cut the bottom fitting off and reweld it 1 inch
Up above the lower weld in the same angle
Then get them to weld a -4 weld on fitting on the bottom with a O ring cap
been doing it this way BEFORE OCMS was out
