I recently got a used '99 foreman 450es. Everything was running fine for a while, but after using it a lot this weekend something isn't right. Now when I try and give it gas, it really doesn't want to go. You really have to hit the throttle to get it to go not very fast even in 1st gear. I didn't want to do any further damage to it, so I just got it going enough to load it into my trailer. In first gear unless I have the throttle pressed at about 50%, it won't even move. The engine is revving up in proportion to how hard I hit the throttle, but it just doesn't seem to move. I am thinking that maybe my brakes are siezed up to the wheels, but I think it's something more serious. Does anybody have any suggestions on things to look for? I am going to check the brakes tonight. Thank you!

Also I had a couple of backfires earlier before this problem came up. Don't know if it's related or not. Should I give the engine a general tune up, such as cleaning the carbs and replacing the plug? Thank you for any advice!
