I just make sure my engine is at TDC after each ride and I haven't had an issue with the stock breather set-up or wet sumping since I first bought the bike and blew all the hoses clear with my compressor. I see no need for any modifications to the system, at least on the stock bike.
The catch can is laying on its side now, hiding in that little nether region behind the crank case. I also put a few shreds of rags in the can with the hope that it'll help prevent leaks once some oil gets in there. Took it for a quick spin and I can feel puffs of engine breath coming out of the blowoff tube, so all seems fine for now. I'll just have to pay attention to it in case the can gets saturated because A) it will probably leak, and all leaks will go directly on my rear tire tread. and B) if the rags get saturated, and get shaken over the blowoff hole, i'll then be suffocating my engine (same as plugging it at the crank case itself).Fingers crossed!still looking for a simpler, more maintenance free cure... (I don't want to continually have to empty this wretched thing)chuck
tooseevee, I removed my side panels altogether for a 'naked bike' look. My K&N air filter is a massive thing, a cylinder bigger than a beer can, so wouldn't fit with the right side panel toolbox anyway. My 'rags' in the catch can are based on your 'old sock/underpants' idea to monitor and absorb oil blowoff. Chuck
