Venture Rob

Just wondering if you need to really turn the fuel cock off after riding (I forget to do it)? Also if the fuel warning light comes on can you move to reserve on the fly while riding? Also manual says to shift from 4th to 5th (O/D) at 31 mph, this seems pretty low to go into O/D gear. Just wondering if most people wait until around 35 - 40 to shift to O/D. Thanks for the help, only had the bike for a few weeks and still getting to know it. Glad I found this site.

Just moved up to 08 Venture from V Star 1300, Like moving from a Chevy to a Cadillac. Just wondered if you need to remove riders seat and gas tank to change spark plugs? If removing tank is it a easy procedure? On oil change any alternative to the expensive Yamalube? Like the Venture, took a while to adjust to the additional weight and winding shaft noise but overall happy. I know we are having a hot summer especially in the midwest but it seems this bike puts lots of heat out by the floorboards compared to other bikes. Thanks for any help and happy trails.
