I have a 2003 ttr 90 that i have recently purchased. the bike is missing the top of the carb(which isnt avaliable on bikebandit.com) slide, needle, spring and so on. i would like to get this thing back together as cheep as possible. -the parts i need will cost about $70 not including the top for the carb -a new stock carb from bike bandit is $293 -after market mikuni 22mm carb cost $45 on e-bay I cant find a stock carb on ebay i have been looking for months. so i did some research and by what i have found the stock ttr carb is a 16mm. so im starting to think i should buy the 22mm carb and try to tune it and see if it will work? I wanted to get some feed back from some other people before I go and waste money. has anyone tried the 22mm carb with a stock ttr and knows it will work?
