......about the Tbird you may not know...the tank is hinged at the seat end so to work on it the tank raises up like a car's hood ! Is that not fantastic?! The spark plugs for example are not accessible the tank on, and i was worried about having to remove it just to change or look at the plugs. But while i haven't done it yet, theres a screw at the front and i believe you just remove that and the tank goes up. Not sure what fuel hoses and all might need to be removed, but i bet they designed it so you don't have to remove anything to lift the tank. This to me is a huge +++.
by the way, the reason a was looking at it to see how the tank comes off is that i want to change the plugs out for Irridiums. Something you may want to consider because 1)-they last nearly forever so the gap won't change at all for nearly the life of the bike, and they will last that long i believe or close. 2)-the added a bit better throttle response to my speedmaster. 3)-and this is the main reason, they smooth the engine vibes a lot, or least they did on the speedmaster. At one point i had aftermarket mirrors that were so blurry i couldn't tell what kind of vehicle was in back of me. Almost totally useless. The plugs smoothed the bike out so much they cleared up about 50-75% and the erratic idle the bike always had was gone. Anyways, the Tbird has 4 plugs so it will be a rather expensive proposition at $20 *list* each (tho i think i've seen them as low as $8) but IMO well worth it IF they work as well in the bird. I'm willing to take the chance. Oh, and i think the mileage improves a tad as well, not not 100% on that.
Anyways, the tank hinge is going to make working on it so much simpler, just thought ya'll would wanna know.
