Figured I would post this as a follow-up/solution that may be useful to others.
The problem was such "crisp" and immediate throttle response in both acceleration and deceleration that it was near impossible to ride smoothly.
My mistake A) I assumed that the sloppy fit of throttle tube onto bar was the cause of the SV's lurching throttle action.
My mistake B) I assumed that the throttle cable adjustment was correct from the dealer (highly unlike me to trust them that much, but trust I did and double-check I did not...)
This is what I posted on another forum...
My bike is transformed!!!! The above suggestions (chain too loose, throttle cables too loose, etc) are all good ones and they may solve your problem, however the solution in my instance was something different. I finally had the opportunity to take bike back to dealer and just ask them to ride it and tell me what they thought. Before they did, mechanic noted that there was NO cable slack at the twist grip. I had figured it was tight/spot-on, but had never tried adjusting it at all. It was exactly the way it left their showroom. They put some slack BACK INTO the cables so that there WAS some play at twist grip and rode it. Granted, they had not ridden it before making the adjustment, but when I rode it after their test ride I found the problem all but completely GONE!
I feel like an idiot for not figuring it out myself, but that simple adjustment was the only thing standing in the way of this being 100% of the bike I thought it should be. I would highly suggest looking at this if none of the other comments helped.
