When I ride I notice that I go faster on a motorbike than I do on an ATV.
Yes, as well as an atv, lawn mower or tractor
Depends on the laws where you are- and you did not give a location. In most US states, when hunting, you may not carry a loaded firearm on an ATV or snowmobile.
there is nothin you can do to an efi snowmobile. the snowmobile is ran by a computer box therefor you can not fight against the box!
Yeah
That would depend if you are asking about the 550 ATV or the 550 snowmobile. Stock HP (have no idea what you have done to "turn it up") 550 Pantera Snowmobile 80 hp 550 H1 EFI 4x4 ATV 39 hp
Atv's and Quads are the same thing. Speed depends on the make, model and engine size.
The fastest stock, production atv is either the Yamaha 350 Banshee or the Suzuki Quadzilla but this is highly debated. Modified or custom atv's can go faster.
dirtbikes are faster, atvs have a lot more weight that the engine has to pull. Dirt bikes are way faster.
Only if you want to find it faster.
it could be a blown head or bottom end gasket- i had the same thing happen on a snowmobile i replaced the gaskets and it cured the problem
the 250r definately. the 250r is a 2 stroke. The 250ex is a four stroke
