loveLSE said:as for initial startup.
are you talking about the warm up period?
if it is, it's suppose to do that.
after start, rpm is bit high (I think around 1200-1500) but in about 5 seconds or so it drops down to below 1000. It's does that to warm up the engine. that's what it says on the manual.
