What is the best carb for a ported cr500 99

[fastback88]

Im looking for a larger carb for my 99 500, it is ported, just wondering what size seams to be the best and brand, also were to buy?

what are you doing with the bike?
what kind of porting?

[fastback88]

gp ice racing and supermotto maybe a little mx .It is ported for more mid to topend power and thats what im looking for. I don;t want a carb that you set the idle buy turning the choke either,

38mm pwk AS will work great for MX, for the other aplications I would think you would want a 39.5 or a 41mm pwk.

My 38 is taper bored to 41+ so I get good throttle response and decent top end too.

Who did you port work?

Hi! I also have a -99 with ported cylinder and some other stuff. I use my bike for iceracing too. I have a Coolhead 66cc, Dynoport MT big volume pipe, power reeds and a PWK 41,5mm. I can't say that i have lost much bottom end power because of the carb. It works perfect. Good idling and easy to jet.
