Thanks again!

To 5th_bike: Appreciated, I'm a UMD student too. I'm found Terp Rider on Facebook and trying to join them.

To Peachy140: Thanks for the advices, yes the spark plug is new, I changed it last month.

I tried the new battery this morning, the bike won't start but at least the starter motor works. The new battery is charged (12.8V), after get it installed, I attempted to start. The sound coming out is "B: Starter engaging, but no combustion", I mean, endless "B" as long as I keep pressing the starter switch. So I guess the new battery works much better than the old battery even with jump start. After few attempts, the bike still does not start, then I get the battery off and measured it(~12.55V).

I guess this is the last simple attempt before doing the detail troubleshooting. From your previous reply, I see it is more like I need to do a carb clean? Seems that the starter is working, no combustion came out because the carb doesn't give out vaporized gas to the engine?
