spittin

Newbie to the site. I have a 07 w/ 650 miles on it . I guess I should tell you that at 400 I did the "stock exhaust mod" with the 5, 1/2 holes in each side. I went for a ride yesterday and noticed that when at a steady RPM, in town, it almost sounds like it isn't quite hittin on all 4 but out...

Hi Im new to this sight . Im having some trouble with my bike. The bike runs like its on 3 cly,s untill i get it up to 3000 rpms then runs fine after that.Local dealer cleaned carbs an instaled new boots. But did not fix the problem. Thanks for any help Sam :bang head:
