help my buel is using too much oil, and it is getting all over my rear swing arm and onto the rotor. it uses oil every time i go any place a good 1/4 qt to a gallon of fuel hard ride easy ride does not matter. it is coming out the vent hose. the po did a "reroute" from the "tank" under the seat just connected both top hoses to each other. is there a problem? of just the way this motor is? | ||

Sigh - undo it- different vacuum pressures bound to make one suck the other - lol - now you'll have to check the primary as well to make sure you didn't scavenge the primary. Route as oem and check/replace valve and grommet. EZ | ||

Or to put it plainly, the PCV hose goes directly from the valve/rocker cover to the ground. It does not need to be connected to anything else. That however still might leave the back of your Blast covered with oil as some Blasts use a lot of oil anyway. OEM basically routes the PCV from the rocker cover into the carb so the engine just burns up that 'excess' oil. | ||

i was thinking about routing it back up to the carb and let it burn in the cylinder, or lube it up a bit. in the am (time allowing) i hope to get back to the bike and check all of the routing. | ||

Thats simple enough! | ||

yesterday, I did the air box mod. I increased the air opening size , totally removed the venturi/bell mouth. I hope to replace the stock filter w/ a K & N soon. I pulled the hose out of the air box and plugged the hole. I turned the pcv valve around so that the hose is pointed to the back of the bike and ran the hose along the frame backbone under the wiring bundle. where it met all the other hoses, I T'ed it into the engine breather hose. It then vents to the back of the bike where the oil drain line is attached. this vent hose is open and I put an elbow on it so it is pointing at the ground. I started all this after trying to find an oil leak. I believe that the leak was from the engine breather vent hose that was tucked up in the frame under the seat. I'll have to watch to see if any drops appear from the new vent location when it's parked . | ||

That sounds like a very complicated way to vent and route the PCV valve. Do you have Cali bike? | ||

It was a ca bike. I think this is a really simple route, and it also eliminates the crankcase venting into the frame. I'de post pics but so far have not been succesful at that | ||

All you need is a hose that goes from the PCV valve to the ground. One straight hose, no Ts or anything else running off the line. I figured it had to be a CA bike from your description. Once you remove the charcoal canister (which you have?!), you just need the one hose to be vented. | ||

Right, and since the crankcase is also vented (to frame) I T'd them together and have just one hose vented to ground. | ||

Okay, now I understand. My confusion is the other vent hose is a transmission vent hose. Normally you'll see very little or any pressure from that hose and you must be sure the engine PCV cant drain or contaminate the transmission housing. Since the engine PCV constantly puts out pressure (except on start up when it 'sucks') I wouldnt hook the 2 together. The reason the trans vent line goes up into the frame is because there is very little chance anything will get blown out of or sucked into the line. Glad you cleared that up. |
