Maybe I can give you some insight on a big motor scooter. I have a 06 street glide with T-man 120. 130/130 at the wheel. It is a carb bike with a 48 mikuni flatslide. The bike has instand throttle response, idles like a harley should, and will make your eyes bleed. At 80 if you crack the throttle you are gone!!. I put the motor in the bike before I picked the bike up from the dealer. The original motor is garage art. Now the not so good.... It has left me sit 3 times when it took out the starter. I have tried 3 different starters (the stock one lasted 2 weeks...). It is tuned to the teeth and has compression releases. Heavy duty cables, battery, ect. The bike is great to ride, but i certainly would NOT take the bike into the boondocks of the western states. It is a big piece of iron and it does have some heat coming from it Maybe the best thing I can say is that if it is your only bike, think twice. I have a BMW GSA and a soon to be picked up 2011 CVO streetglide to fall back on when the bike gets an attitude... Just saying. Spook.
