I have a 1996 250 polaris trailblazer with the stock mikuni VM 30mm carb. I have come a cross a Mikuni 34mm carb from an old snowmobile I know that the 400 sports use a VM 34mm. My question is have they changed over the years and will an 1982 VM 34mm Mikuni work on my trailblazer. Any advice you can give me would be greatly appreciated.

 

I have a 34mm mikuni from a Scrammy that worked real well. It took a little research to get all the jetting right but it made a big difference. I am not sure if the older 34mm mikuni is the same but if it is I will tell you the exact jetting for it. I would think that they are the same!! What snowmobile is it off of?
