I got 58mpg on my last fill up. Will continue to track. I use my bike to commute so I should be filling up at least once a week.

I'm eager to hear the results from Blackstone Labs. Please do keep us updated.

Lee, are you seeing any fuel in the PCV catch tube?

It filled halfway on a 300 mile trip (other RX3 had none) and since has only had small amounts.
The oil did smell like gas when I changed it. |

I just got back from a 120 mile ride today and got about 55.6 mpg. But I'm 280 pounds fully dressed, and it was all highway at nearly wide open throttle, all of it above 8,000 rpm, and a good portion at 8,800 - 9,000 rpm. In my opinion, that's pretty darned good considering that power to overcome drag increases exponentially. I'm confident that if I kept the speed and RPMs constant around 8,000 RPM (versus the acceleration away from traffic, etc.), my fuel mileage would have been better.

Got 49.6 today. (averaging 53) I'm going to need a fuel can for long trips on this bike!
Good news is less fuel in the campfire tube after flipping the contaminant separator. Riding on December 24th in 63 degree weather is kinda nice! |

In case anyone is unaware, the OCS (oil contaminant separator), otherwise know as the 'campfire tube,' is frequently installed upside down at the factory. Here is a photograph of the correct orientation of the OCS. The hose should connect at the top, with the clamp at the bottom. Here is a photograph of the OCS in the incorrect position. There should not be a large loop, or sharp bend in the hose coming from the crankcase. Please Note: I have edited this post because I accidentally placed a wrong photograph in the original post. My mistake was caught by RedHawk47. Thanks for pointing this out, RedHawk. Please excuse my mistake. I'm sorry for the resulting confusion.

You are going to drive me crazy. In both of the photos the OCS is in the same position. Also, I don't think the loop in the tube makes a difference as long as it is not pinched off. I don't remember what thread the earlier photos were in. I finally when out and looked at the OCS on my bike and this is what I found. There was nothing in the "campfire tube" and nothing has ever leaked from it. Because of the weather since I got it in October I have only run two tanks of gas through it. Mileage are 63.9 and 61.6 MPG. So, is my OCS correct or upside down?

It's not so much about the hose, Dan (a lot of Dan's here) as it is about the orientation of the workings inside the OCS.
So far I have only had juice in my tube twice, and there was no difference in how I operated the bike. I keep reading that second statement and something just doesn't seem to sound right. |

Redhawk, based on your picture, your OCS is upside down. The metal strap should be below the hose to the crankcase.

However, lower pressure also promotes the condensation of gases, as shown in the video below. Therefore, when the OCS is positioned upside down, the lower pressure increases the condensation of fuel vapor.
The video below shows the wing of a Boeing B737-400 taking off in the rain from Seattle-Tacoma airport. Just as the plane starts to lift off the ground condensation is observed over the top of the wing. This phenomenon is caused by low air pressure over the wing causing water vapor in the humid air to condense.

When the OCS is positioned properly, the cone of the screen is located at the top of the OCS. As the fuel vapors pass through the second screen, their velocity is decreased. The decrease in vapor velocity results in an increase in vapor pressure. This higher pressure helps the volatile fuel vapors to remain in a gaseous state. The less volatile water vapor condenses to a liquid, which is collected in the down tube. More of the volatile fuel vapors remain in a gaseous state, and are drawn into the air box, where they are consumed in the combustion process.
Detours has verified the collection of less fuel in the down tube after he flipped his OCS to the correct orientation. http://www.chinariders.net/showthrea...el+tube&page=9

Spud, Jay, Detours
Thanks for setting me straight. Spud - what was making me crazy was that you had two photos with the OSC in the same direction and you said one of them was wrong. It's all OK now. Thanks

You're welcome. I re-examined the photos, and you are correct. I made a mistake, and I'm sorry for causing the confusion. I have corrected the original post. The correct photos are also shown above in post #50, and post #51.
