your risking scattering the engine !
Yes I know you hear all kinds of guys doing that on Youtube, their idiots ok !
....
when the rev limiter is kicking in and making the engine flutter at WOT it's the bike's last ditch effort not to destroy itself...
....
in the 2 years I've had my 2012 I have never revved it so high as to reach the red line. ..... Brake that bad habbit or you will be walking...
yah it sounds cool, but it will destroy the engine !
.....
.... I have no doubt I will be Chided for that statement ! by guys on here that routinely Over Reve their bikes and have been doing it for ages and got away with it so far.... but is it worth the Risk ?
....
For the bar-end mirror just take a knife and trim off 1/8" of the rubber on the end of the grip or just move the whole throttle grip in towards the tripple tree a bit. there should be no drag from the grip itself anywhere
....

I think Gordon ( Ducattiman ) is right it sounds like it's out of Sync to me.
Buy some thick vinyl 1/4" hose and make yourself a carburetor synchronizer
with some 1/8" hose on the ends so you can attach to the intake
and Sync those carbs ! but I could be wrong on that...
.....
just my 2 cents ...for what it's worth.

Bob.......
My understanding is it cuts the spark to the first cylinder last time I did so I had it cut in around 12.5k I think from what I saw in ninj250.org my model should be 14.5? Nevertheless between the mouse nest with a pound of tissue (I replaced the air filter) and oiled it and got the valves in spec not too shocked it reached it with no effort.

The carb sync will probably be before the weekend it’s pretty hard to work in the cold lol.
