new and rough running?

[maxed66]

So, recently I had my 1000 km service and now have about 1800 km. I have done lots of fun riding, a few wheelies, but mostly pretty tame and normal riding. My bike has undergone some changes since the day I rode it off the lot. First, it has loosened up. That is nice. I did do a nice trip through the alps using the lower gears quite a bit. The first thing I noticed was it seemed to "pop" off of higher RPM deceleration. No biggie, just the cats hot, I figure.

But now, with barely 1000 miles ont he bike, the thing is running less smoothly than it originally did. I sort of noticed this before my service, but it was not to bad. Today,however, i really began to notice that at a constant RPM, it is sort of bucking kicking. Ok, it is not running like a Harley ;-) , but it is not as smooth as it should be IMHO. I imagine fouled plugs or out of sync carbs. Bummer for me it is FI. How do you sync throttle bodies and how do you get at the ***** plugs???? Fouled after 1000 miles??? That does not seem right!

Anyone with a similar experience/solution??? Ideas???

So, it was bad enough today that I wanted to show off to a friend in a parking lot. In 1st gear I gunned it for a wheelie at aobut 3000 RPM..... it just bogged and let a pop out the exhaust! Uhm, wasupwitdat!!!!!

mine was doing the same thing. turned out one of the rubber tubes that runs from the gas tank to the ground had popped off. this caused a bunch of vacuum in my gas tank. have you tried opening your gas lid lately?

also, have you checked your chain? does it have 35-40mm of play?

For sure not normal, I would do as Tekmoe suggested check tank lines and then maybe plugs. Bike should run smooth all the time. If that fails you should be under warranty yet, take her in.........
