    I put the new Mikuni carb off my 09 WR125 on my 92 WR360. Fit great and starts and runs good until the top end. Has the pointy stock neddle (power up needle) and a 450 main. I'm thinking the main is way to big. Starts great, responds great till about mid throttle and then does not want to rev out. Looked at the manual and it looks like I should be closer to a 390-400 main? Sounds about right?

    Thanks.
