I have a '00 wr400 and I'm sick of it gumming up and having to work on it every spring to get it half way rideable. It has the "won't run without choke" & "no idle" issues. (I've soaked and cleaned which helps for just a little while, maybe a month) I have added a fuel filter, stabilizer, run the carb dry, etc...frankly, just tired of working on it and want to ride more than wrench. Is there a recommended replacement carb for this model year? Thanks.
