i need to get the crankcase breather out of the air box and into a catch can. i did a search here but i can't seem to find what i'm looking for. can someone explain to me (pics are nice too) where you located the catch can and then give me some ideas on making a catch can. where can i get a breather/fiter for the can? i think i know what to do but please include as much detail as possiable. thanks George |

Do you need a catch can? Its going to collect a lot of oil! You can just use a breather filter mounted out of the way (however if you blow a lot of oil it will coat everything around it). So I'd use either one or the other. If your catch can is clean, you shouldnt need a filter. Anything can be used for a catch can. I use an 8oz "Harley Wash" (pun intended) bottle mounted on the frame where the stock airbox used to be. But you can use whatever you want, be creative. Just make the catchcan hole/hose a snug (not airtight) fit. On my streetBlast I reconnected it back up to the intake elbow (Pro Series) as I got tired of cleaning up the oil all over the back of the bike. The raceBlast having had the top end redone, uses very (very) little oil at all. The catch can is usually almost empty. Did you see Vtec's breather on his recently posted carb pics? |

i still have the stock air box on my bike so i am having a hard time trying to find a place to mount a catch can. instead of using a catch can i was thinking of this. i'm not sure how this would work but i was thinking of taking the breather hose out of the air box and then plugging the hole in the air box. then from the T run a hose to a fuel filter, from the other side of the T where the hose goes to the carb bolt would get plugged with a bolt and just hang there. i planned on using a clear plastic fuel filter so i can see when it gets clogged so i can replace it. as i said i am not sure if this will work but unless someone tells me otherwise i think i'll give it a try. George PS: i did not see Vtec's pic, can you post a link for me? |

As long as the line is vented, you should be okay. Someone else here is using the clear fuel filter as a breather vent, but I would think it would clog up and turn black quickly. They are cheap and easily available though. http://www.badweatherbikers.com/buell/messages/20164/6812.html?1159834018 (Message edited by gearheaderiko on October 02, 2006) |

I used the plug for the vent drain tube where the Tee would connect up to the air box hose. Then I used a straight hose connector to connect the hose coming from the rocker to the now unplugged hose. Both bikes now just vent out to the atmosphere. There seems to be no problem with this and there is no oil leaking on the rear brake or swing arm. I did not use a filter as I can't see contaminates going back up into the hose that far into the engine. |

Swampy is right! It would be a long way for contaminates to travel for it to get into the engine (the PCV line only sucks on start up, then it blows), the filter is just an added precaution. Without a conventional PCV filter and draining it to the ground, that would decrease the likelihood of it getting all over the back of the bike. Put that fuel filter in line and you could wind up with a very neat set up. I might try something like that myself on the street Blast! -You must make sure it vents properly though-. Old air cooled VW's used a soft closed ended hose with a slit in it that would open only when the engine had crankcase pressure. |

i have another question to ask, if i make a catch can does that have to be vented? can i run the crankcase breather hose in a can, put a petcock on it so i can drain it and be done? if it does need to be vented i can just attach a small K&N crankcase breather filter to whatever i use as my can, correct? this whole thing is driving me crazy (i know not a far drive.....lol) but i'll figure it out. |

The crankcase has to be vented. The can would have to be vented also. If you don't you will build up crankcase pressure and run the risk of causing a seal or gasket to leak. |

i was talking to a motorcycle mechanic today and he adviced me to leave the breather inside the air box. he told me by moving the breather outside the air box the bike will not make as much HP. he also said the fine mist of oil that goes into the carb helps lube the top end of the motor. as if i wasn't confussed enough before i'm now unsure what i should do. on another note i installed my new bars & grips today. i purchased both the sport bike bars and the daytona bars from chaperel. the daytona bars seem to be just what i was looking for so i used those. i broke my wrist in the spring and with the original bars my right wrist would hurt after a short ride. with the Daytona bars after an hour ride my wrist still felt fine. the Buell traction grips are by far the best grips i have ever had on a bike. one problem though, after installing the bars & grips the bike was very hard to start and when it did finally get running it ran like crap. it seems someone turned the gas off and forgot to turn it back on again......i blamed my wife cause i would NEVER do anything so stupid. |

Nytrashman: Do not beleive you were talking to a Mechanic, BUT a technician ... The Rocker Breather in dumped into the Air Box because of EPA Regulations !!! |

Pre emission days.......there was a part called a "Road Draft Tube" It was a vent tube that went from the rocker box to below the engine, pointing towards the ground. The mechanic was right because the vent tube entering the intake is an emission device to keep combustion "Blow By" (The gasses that get past the rings) from entering the atmosphere. When your bike gets broken in there are less of these, and as your bike ages and the rings wear there are more. The "Road Draft Tube" set ups on my Blasts do not spray a fine mist of oil, in fact there is hardly anything that comes out of them at all, maybe a little oily condensation. Oil mist that is taken into the intake is burnt and causes carbon deposits in the combustion chamber which can cause pre-ignition and detonation, which can actually harm your engine. The top end of the motor is lubed internally with oil galleys directing pressurized oil to the underside of the piston and up through the push rods to lube the rockers. |

A picture is worth a thousand words.... Here is a picture of the Little Kids Blast, and the exit of the draft tube where it exits by the swingarm. There is no oil mist on anything as you can see, and you can also see that this Blast is not taken care of appearance wise, so this is not a freshly cleaned area.

"which by the way is oil mist free" Individual results may vary! (meaning that some bikes will blow a lot of oil and some very little and assuming that Swampy's top end has never been done, he's got one of the better ones!) |

I think that when the crank case vent is all being directed to the air cleaner it has no place to dissapate and makes the air box look the way it does and leak so much. Also I have noticed that the air box still spews but it is fuel from reversion in the intake tract. Can't help that.....well I'm still thinking about it, and with the advent of the wire wraped fuel filler hose, I think it can be cured. Neither of the Blasts have had anything done to the top ends, the Big Kids is at 19,000, and the Little Kids is at 9100. |

thank you swampy, the pic is worth a thousand words and latter today i will re-route my breather like yours. if i get lots of oil on my swing arm is there anything i can do to stop that? i'm not sure how much oil is blowing out of the breather tube but the inside of the air box always has a coating of oil on it. i am also not sure what gearhead means when wondering if your top end has ever been done. anyone care to explain that to me. |

Swampy: Worth a thousand words is right !!! What are you going to do about the HOT EXHAUST blowing on you rear TIRE ??? |

NYtman: Theres not much you can do if it blows a lot of oil except route the breather to a different location (coating something else), use a catch can or plug it back into the air box. Having the top end done means rebuilding the piston, cylinder and head. You can usually do a better job than the mass produced factory originals because you'll be paying closer individual attention to your engine. Some factory engines will turn out better than others which is why factory race teams usually have access to the parts that come out closer to perfect. |

swwampy.......are you using the stock air box? i had a very hard time getting the stock air box to fit on properly when i rerouted the breather hose like yours. |

NYtrashman, What? I am using the stock air box. Do you mean the crankcase vent hose is getting in the way of something? Once you take the Tee out and have one solid hose(connect the hose from the rocker cover to the hose routed to the swing arm) you should have one long hose running from the rocker cover to the swingarm area, The plug that was plugged into the end of the crankcase vent hose at the swingarm end, is now used to plug the end of the hose that is now sticking out of the air box where the tee was. None of these changes should have any clearance issues for the air box. Now, on one of the Blasts I have the vent hose routed on the left side of the frame to the swing arm and one routed on the right side of the frame and crossing over behind the air box to the left side by the swing arm. Either way it all fits. Its a little late but I will pull a fuel tank and take pictures. It should work out for you well. |

For the love of Christ someone tear the caps lock key off Buellistic's keyboard. EVERY POST of his has CAPS LOCK somewhere in it. Too bad his advice is about useless. |

That exhaust simply makes the tire even more stickier in an ass-hanging-off, peg-scraping left turn, IMHO. |

Do you have 12volt to the coil with the switch on? |

Very likely a safety switch. Neutral, clutch, kickstand or Bank Angle Sensor. But it ran fine before you did the stator? |
