Its a combination of jets and tuning. Try using the serach function as this problem gets "solved" and least once every 2 or 3 months.

hey mate i just posted a link for carbi tuning try all this and read it all before you get the wrong jets cos someone told you to get a 105 main jet which cost $20 when you needed to adj your needle jet c clip which cost $0 and less time so just click this link and read on Mikuni carburetor operation and tuning
