My 1998 Polaris Sportsman 500 carb is worn out...It's a factory original 34MM Mikuni...I want to replace it with a 38MM or larger Mikuni so I don't have to pay the nearly $300.00 price...I am a fair mechanic & have the stock carb off & disassembled, so I am willing to "adapt" in order to get one of the new Mikuni TM flat slide carbs to fit (or any other Mikuni series..??)...Hoping someone has done this before & can save me some searching....
e-bay will probably be your friend on this one.
You'll need the intake boot ,carb., connector tube from the carb. to airbox and i think airbox too.
You may want to stick with the BST40, so's you can still use the stock choke, pretty reliable carb.
