I have a new to me 2015 GRiSO 1200SE. It has low miles at 1600. I am making mods as popular here. Full service, valves, etc. I will pull of the evap canister and connect the pipes from the tank to each other. I am off track of my Question. Has anyone taken the crankcase ventilation canister off? The system collects the oil to a drain tube and sends the airborne particulates the air cleaner. This is California EPA stuff but just adds to the carbon buildup on the intake valves and adds weight to the bike. I would pull a line off the crankcase and add a small filter in place. Similar to a PCV filter on a racing engine. Thanks guys for your thoughts. Scott.
