I am new to this forum as well as the 2003 royal star venture that i just bought. I have searched all around this forum but haven't found the exact problem that i may be having. I say "may" because i'm not sure if this is the way this bike is supposed to sound and perform. This bike has 3200 miles on it and looks brand new so i picked it up for a deal. I am used to riding v-twins like my raider.
I trailered this bike back home and I believe the previous owner hasen't ridden it for a few months.
When I started it, it cranked right up and idled what sounded a bit rough but not bad, when i rev it while in neutral it sounds nice and smooth but throttle response is a bit bad.
The real problem seems to be when the bike is under load, when i take off in first gear the smooth sound turns into a sort of a - putt putt putt putt sound like it may be missing, it also seems to surge a bit at the top of each gear. this thing seems to have very little power at top gear, when i twist the throttle at 60 mph it is slow to 70 or 80 mph, even if i downshift to 4th it makes noise but doesn't seem to go anywhere. I also get small backfires while downshifting and letting off of throttle, not bad, but i can hear them.
I'm very accustomed to my raider which is very snappy at any gear, maybe its just me but there seems to be a problem.
