    2001 Polaris Virage - Smooth Throttle Control

    Hey guys. I have a 2001 Polaris Virage 700. It's running awesome. The only thing is the speed is a little hard to control from stop to about half throttle. Feels like it either wants to go slow, or is you start pressing into the throttle a little, the power surges on too quick. It's not horrible and you can smooth it out if you are a thumb ninja but new people on the machine keep getting whiplash lol. Again runs awesome all the time just hard to control the throttle at lower speed. Higher speed very smooth and responsive. Any threads on this already?

    Basic Maintenance Completed:
    New Gas Lines.
    New Battery
    CDI replaced with used stock CDI (spark issue)

    Has it always run this way or has it developed over time? Check your plug color...sounds like it could be a jetting issue. When were the carbs cleaned out last?

    You know I should know better lol. I really just started driving it this year. Picked it up not working from a previous owner late last year... Went through all the testing as listed on this site and was confident needed CDI(no spark) Put in new(used CDI) and been running like a champ this year. So yeah just getting it fine tuned now. I will start with carb clean and report back!

    Please explain further....new(used CDI)? Where did you get it from? Was it a used stock one or one that was reprogrammed? Your issue could also be related to a timing issue which comes from the programming of the timing curve of the CDI.

    It was a used stock one from same model as mine.. Found from a wrecker on eBay as parts are obviously getting hard to find. Again my machine is running pretty darn good and some people might not even notice if you just pin and go all the time lol. Let me know ur thoughts. I'll still clean carb as who know last time was done.

    Yeah hard to say when you just got it so don't know the history. Hopefully it's just a good carb cleaning but it may be a jetting issue on the low and mid jets...bogging is usually a rich condition...but could be a complete opposite as a lean conditon, so that's why I suggested looking at the plug color after riding in that bog range for a minute. When riding and it's kind of in that bogging range, have you played with the choke lever moving it slowly to full choke to see what affect it has? If it gets worse, then you are running rich, if it gets better then you are running lean.

    I will try your suggestions and look at plugs, play with choke etc. I wouldn't even say it's bogging.... Just seems a sharp transition from slow to mid-range speeds. Maybe that is bogging lol. However, if I really pay attention to the thumb throttle I can keep it smooth but it takes a ridiculous amount of thumb/mind control. Throttle cable seems in good shape. I'll start with some of your suggestions and report back.

    Do you know if there has been any engine work done to it?...if so, what? Higher compression heads installed? Sometimes modified skis that have had engine work like porting done to the cylinders and high compression heads can react this way. They hit that port timing at mid range and they will surge like crazy. My Virage TX does this at around that 4400 rpm. It wants to either stay below that rpm or it just takes off and it's hard to make it "smooth" all the way to top end.

    Not sure on any mods. Looks stock to me. Compression is even around 140 last time I checked. I will report back!

    Finally got it out for a spin. Here are the plug colors after keeping it the the low rpm range for a good couple minutes. Carb is getting cleaned now. Here are the jets as well just for fun....
