m-x-z583

Hey everyone!
First time posting on this site gonna see how it goes!

Well to start off i just purchased a 1996 mxz 583, we had a huge snow storm today so i decided to take it for a rip!

Everything went perfectly through the trails until i opened her right up. At around 100 kph and about 7000 rpm the sled just wouldnt pick up anymore. I could hear a bogging sound but i know there is still alot more speed capability in this machine.

Anyone have any ideas?

Thanks in advance!
