O.k. I've had my Monster for a relatively short time. I got it in July '03. I love it but the only real problem I've had is it kind of hiccups from a stop when I roll the throttle ( regardless if it's an easy roll or I snap it). It would stall but I've learned to work with it. It only happens when the bike gets hot 200+. A couple of times it's just stalled out and it is real hard to restart. Also if i've been riding a while and shut it down and try to start it after it sat for 1/2 hour or less it is difficult to start. If I am at a red light and am in neutral and shift into gear it will occasionally stall then. This is always when hot. My local dealer told me it was the champion sparkplugs and I should upgrade to NGK . It is a 2002 with 4500mi on the ticker. Has this happened to any other 600-620 owners? I don't want to spend money of stuff I don't need. Any help is appreciated.
