Hey i've got a 1998 vn 1500 classic and i love the bike, but the bike has no power after 120km/hr and for a 1500cc it is kinda disappointing. It also has poor fuel economy, I can only get 170km out of a tank of gas whether its cruise'n down the highway or driving in town.
I was told from the dealer that these bikes never were great on fuel even when they first came out. The bike has a set of Vance & Hines pipes on it and also has a jet kit installed in the carb. I am wondering if anyone else has had any of these problems and if it can be fixed. Like i said i love this bike it starts and rides great.
Thanx in advance for any help
It could be that whoever redid the pipes put too large a main jet in the carb, causing it to waste fuel and 'dog out' a bit at higher speed acceleration. But it could be a lot of things. Could be plugs, could be fuel, could be fuel/air mix (though less likely at higher speeds), could be air...When my bike was getting poor mileage and running sluggish, I took my air cleaner out, put the cover back on, and took it for a spin (if you do this, make sure it's not a dusty day outside!) If it runs better and gets better mileage, it's getting too much fuel. If it backfires and runs hot, that isn't the problem. Mine got much better mileage and ran better, so I knew where to start.
