    Question Carb and Choke Tuning Questions...

    Hi Y'all, New guy here.

    I've got a 1998 Yamaha Vmax 700 Sx. The sled runs OK. Breaks up mid throttle, and won't idle without the Choke part way on. Even after an hour of riding when it's all warm.

    I would like to pull the carbs and clean them, and I also want to set everything to stock spec to start with. I'm also guessing that I need to adjust the Choke cable somehow?

    Looking for some tips, advice, and the specs obviously.

    Any help is fully appreciated. I can turn a wrench and do anything I want, I just don't know carbs that well. So hit me with it, and I'll give it a shot!

    Thanks, guys

    Welcome, I believe those are rack carbs, as in the cables attach at one point and then linkage does the rest to make them function in sync? First and foremost is getting them out, torn down, cleaned and checked out for any parts that need replacing. If you can turn a wrench you will have no problem getting the airbox off, cables disconnected and the carbs removed and on the bench. Unfortunately I can't help too much spec wise. You may want to check out https://totallyamaha.com for specific info or even buy a manual for that sled. Good luck.
    Polaris...it IS the way out!
