carbs

[400EXTRD]

I own a 2000 400 ex my mods are basic with the sparks x-6 exhaust, ignition key, filter, rev kit, 14t front sprocket. I only ride dunes and wanna get more power to hang with the raptors. Will I benefit from a fcr 39 or 41 carb? Which one and how noticeable will it be? Thanks

With thoose mods you may want to consider the 39 FCR. With thoose mods you will loose low end, it would be worse with the 41mm. The FCR gives quite a gain but you may want to consider a cam or a 416 or something first, it may produce more bang for your buck then the carb. FCR's are rather pricey.

without boring my engine can I get a new cam? How hard is the install. I'm looking for the most power I can get before I go to a bore kit. Thanks and brand name would help

if you are wanting a cam I would suggest a cam with a high compression piston you will see better gains this way

I wanna order something that is gonna give me more power. With my mods what would you recommend me doing? I'm open to all possibilities. Cam, carb, even a bore kit if I can get it done quick.
