Hi guys. So I have a 38mm FCR Carb that I actually have laying around it was from a YZ250F That I Replaced the Carb on and I kept the old one. It's still perfect shape and works just fine. I was curious if it would be big enough "or enough CFM" to fit on my 2005 TRX450R? Because I'm running the Stock Carb still and would love to have a little better performance and I know FCR Carbs name a Night and Day Difference in Power and was just curious if the 38mm Would do a better job on my quad. Also if it needs to be Bored I can definitely take it to bore it. Thanks guys I Would be Happy as a Pig in shit if this turns out to be able to work.
