Not sure if I posted this one before , but here is a pic of my engine compartment . its a good pic to get an idea of where you want the filter. I think i posted that my plastic elbow was a 45 degree , its actually a  , sorry about that " it was a while ago " .  |

GEH
I see what you are talking about with the 45degree bend. But how effective is that at removing the filter from the engine heat?

GEH I see what you are talking about with the 45degree bend. But how effective is that at removing the filter from the engine heat? This way the filter is much closer to the open air. You cant see it from the pic , but it sits a little lower then the side plastic panel, and its actually touching the bottom of the panel. Since the hot air is moving back , the uni " in this position " is sucking at 360 degrees therefore pulling some open coolr air. When the filter sits directly behind the carb , it is directly in the hot air path at all 360 degrees of the filter. I can't say its not sucking in any of the hotter air , but I know its at least sucking in some cooler air. The bottom and rear of the uni I the pic above , will be sucking in the cooler air. Since the upper and inner side of the filter is still in the compartment are , I would expect it would still suck in some hotter air, but its still not centered in the middle of the enime compartment , so I'm not sure if that helps a little or if it doesn't " when it comes to the top and inner side of the uni " |

You have it going to the right side, directly above the hot exhaust. If you swivel the elbow and head it toward the left side instead the filter will be sitting in significantly cooler air. Then you will be hitting your 70mph. |

Then you will be hitting your 70mph. I see what u mean. The filter is over the exhaust side. I would expect the air movment would push the hot air back before it rises to the filter , however it would be worth flipping to the left side , this way I'm not wondering if its sucking the muffler and header heat. At stops and idle , the heat would rise up to the filter . im def gonna flip it , thanks !! |

How bout Wrap the Head pipe with DEI Header Wrap.
Keep's the Cooling Fan from sucking in that Hot air.
Leave the Intake alone since the Header is Wrapped.

Well, after running around town all day trying to find a suitable rubber hose I finally set up my uni. Used 1 5\8 rubber hose, and a degree copper elbow and it worked perfectly. Tried a 120 jet and it was ok, then tried a 130 and it was boggy, so I threw in a 125 and it seems just right. I have the uni going to a stock carb, and a larger diameter header and free flow pipe. finally its set up how I want so I can stop tweaking on it and just ride....for now haha I have a feeling this scoot will be a neverending project for me |
