Well, new/old that is. I just became the proud owner of a 2000 Monster 750. It starts and has great throttle response all the way until the throttle gets about 10 percent open. From the reading I've done I think I need some needle valves. Other than that I'm in Texas, new to riding on the street been a dirt guy up until now.

Good luck with the carbs! Welcome

Great little bikes and so much fun to ride.
Place a question in the Tech section for some advice.
