Help Carbing...

[saphunt2r]

This is what I have an 01 400 bored to 416 with a wiseco 11:1 comp, hotcam stage 2, piped, fresh valve job with new valves And a K&N filter with open air box…should I stay with the stock carb and rejet it or go with a 450r carb??

The stock carb will work fine, I used it on my 416 for years. But if you want to squeez every bit of power out of it, I would upgrade. I didnt go with a 450 carb, I used a 39mm fcr and it made quite a bit of difference on low end but the 450 carb would be great and its cheaper than a fcr.
