Yep, the tall seat does help out a bunch for us, um, bigger kids! Mine is the SDG. The difference is huge over the stock seat in how the bike fits. It might be just the cost-effective ticket for ya. Seems like those lift kits were relatively pricey comoared to the seats.
And, I think that vent hose just gets piped down the side of the case! I got the Takegawa filter now (K&N clone) and it has one port on it, so that's where it is now! :thumb:
