Did you remove the baffle or take out the quiet core?Neither will really help look into a slipon.Also Look into sprockets.

ok if u r mechanically inclined do a hot cam stage 2 and a hi comp piston... 11:1
under 300 bucks and will make your four wheeler come alive

exhaust...

how about suspension...depending on the type of riding you do...you might look into some different shocks.

I also have an 07 and love it.

IMO i'd sell it and get a 450R while you can still get some good $$ out of the 400.

[casey_lamm]

considering you don't know the riding style or skill level of the riders in question how can you make that statement.

Recommend a bike that is more maint., and generally less reliable then the 400.

But everyone gets there opinion.
