Several carbureted 600s have needed to change main jet sizes as well. This engine has a bog, randomly the engine will not respond and just bog down, sending you abruplty close to the windshield!!

Just picked up my own dragon 800 sp yesterday, 0-100 in the blink of an eye, and after about a mile of holding. After that the sled lacks power.
Competition data We dynoed the 800R powerplant from Ski-Doo at 155 hp at 8,100 rpm, which was impressive. It's important to remember that not every sled that comes off the line makes exactly the same horsepower and it's nearly impossible to re-create the exact same dyno pull every time. Yet, in our dyno tests we did not exactly see the horsepower numbers we thought we would, but did learn a lot about the engine. It fixed the hesitation on many of my friends sleds, and polaris covers the reflash. Now is the time of lightweight big 2-stroke 800 twins. We put the Polaris 800 Dragon on the dyno at Dynoport for several runs and also received data from the good folks at DynoTech Research. The sled is a rocket out of the hole! This problem is widely rep.
I owned one before and it did the same thing so the next year I swapped it. A friend of mine has a 09 dragon 800. This year, with ever-growing concerns about deteriorating fuel quality, the rich fuel mapping may have been done to provide additional protection to the engine. While this is lower than the Polaris-stated 154 horses, it's still darn good for an 800cc engine. The shock package is excellent for the trail, but they need to be revalved if your the kind of person who hits large jumps. I would like to see it run good and stay with the guys for a few rides.
Stock you will max out at around 97-100mph. I also owed a 2007 Polaris 700 dragon in which I expierenced the same problem. To view more specifications, visit our. Yamaha competes in this power region too with its 149-hp Genesis 4-stroke engine. Polaris tells us it takes 300-400 miles for break-in and only after that will consumers see the Dragon's peak power. I have heard rumors of a fuel system reflash, but nothing yet? By continuing to browse our site you agree to our use of data and cookies.
Otherwise a great handling sled! Early optimism We were optimistic after many late season test rides on the pre-production Dragons. We also heard that the rings on this engine are particularly hard for longevity and heat protection. Having looked at these stats again, it seems as though everyone is chasing Ski-Doo's 800R motor as far as pure stock power production. Dealer put some new pistons in it so its got all the updates. It also is apparent that this sled responds well to bolt-on mods and 93 octane gas. Can anyone help with any ideas of what can be going on? PolarisStarPower is always open to donations. So with a Y-pipe and more, this sled will most likely be a 160+ hp machine.
With the Power Commander, DynoTech saw more than 153 hp, very close to Polaris' stated figure for the Cleanfire Injected machine. You better hang on from 0-85mph. . Any help is greatly appreciated. We would also much rather have a machine that protects itself and has the detonation sensor retard on the engine sooner rather than have a burn down. Interestingly, the old Polaris 700 Dragon netted 135. We use data about you for a number of purposes explained in the links below.
We took a look at this segment in depth in our 800cc short-track comparison story last issue and further scrutinize it with our 800 crossover comparison this month. . . . . .
