G'day, Am trying to source a pumper carb in the US, and being from Asutralia this is a bit tough. Having a little trouble finding someone over here with them, and thus far the parts from the states have been way cheaper. Given my two young kids and wife monster, that is a good thing. What roughly are the Mikuni's and Kehins worth new??? So far I have a price of $600 for the FCR which seems a bit high... Oh yeah, the crankcase vent on my bike looks pretty decent, about 20mm (4/5 inch) outer size from the top of the case to the inlet. Is this really restrictive, it seems pretty well sized to my limited intelligence..... Greg.
