Here's what I would start with.

175main
50 pilot
needle all the way down on the clip (5th position), maybe only the 4th clip if that is too rich. I've seen the needle selection vary a ton between just a few 450R's with similar mods. I've had one where 5th clip down on the stock needle wasn't enough
HRC needle would also work in 3rd or 4th clip.
fuel screw 2 1/2 turns out from fully seated.


Should get you in the park, the rest is up to you.

Ok, Thanks alot. Thats all i was looking for was a starting point.
Thanks Again!!

I had about the same set up. Go with a 180 main. Raise the needle one notch. Go up to a 50 pilot 1 1/2 to 2 turns out on the screw.
