Since winter is dragging on here in WI decided to start on some tuning. Just did some other maintenance so reset TPS and loaded standard race map as a starting point. Ran like crap. Reloaded stock map ran OK but started hanging at 2k returning to idle. Crap! Ordered new seals and started tear down. Noticed this nipple on right side of TB right above the fuel rail? Is there supposed to be a line or something to it? I recently bought this one (my 2nd 06 Uly) and I am positive that there was nothing here when I took the base and velocity stack off.

Thanks
Ken

This goes in under the butterfly. Should this of had a vacuum cap on it the entire time?

So been sucking unfiltered air for who knows how long??? [mad]

I just picked this one up last fall and haven't been able to ride much due to the awesome weather here in WI. Need to replace intake seals anyway so might as well pull the TB and give her a good scrubbin. Good Times!
