Rough and High RPMS at Idle
Hi I'm brand new to these forums; I bought my 09 250r about a month ago with 15,500 mi. I began noticing the bike's RPMs fluctuating about 250 RPM at idle (the needle is not steady, the engine kinda lobes). When I've been running it for 10 mins or so its right around 1250 - 2000 rpms at idle (still rough), which I feel is a little high since most cars I've had are right under 1000 (I understand, motorcycles are a different beast). I've also noticed a strange whine coming from my gas tank, most noticeable when I cut the engine off. I noticed it when I purchased it, but the previous owner had asked a dealer and the dealer said it was just the air/fuel balancing out or something.
Are any of these signs of something significantly wrong or should I just clean out the carbs? The bike is due for a major service (15k) so I guess that's always an option.
Thanks for taking the time to read my first post, I'm looking forward to becoming a member of this community.
