Hi there, I recently changed the plugs on my 07 RSTD, it should be the same as on your Venture. I found for the rear ones, it's easier to get at them when you remove the seat, then it's pretty much a straight shot to the plugs. The front ones, however are another subject. I found it relatively easy once the tank is removed. You need to remove the "dog bones" (I did them one at a time) and it wasn't too bad. I'm not sure if you can take the dog bones off without at least raising the tank....I just took it off to avoid dinging it up. Hope this helps!
