Raptor 350 Jetting ?'s

[Yamaholic]

I am sure this has been asked a million times already, but I can't seem to get a definite answer on what jetting or carb mods need done. HMF recommends dropping the clip one position with just the slip-on, and to shim the needle .030" with the UNI filter. Would this be correct?

Specs:
'06 Raptor 350
HMF Performance/Sport Series slip-on exhaust
UNI filter w/stock airbox lid on
Elevation: 1122 ft. above sea level

Sounds about right, I had to raise my needle ( drop a clip ) just because I removed the spark arester and put an aftermarket foam filter on the stock cage. These things need rejeted right off the showroom floor, so if you do any thing to them they need more fuel
