Hey guys,

Here is my scenario 2003 prairie 650 just hit the 100 hour mark. I took it in for the 100 hour service had a new belt, oils change and tuned up.

The problem is that now it is slower on the top end than before I took it in.
before the service it would top out at 68 mph on the speedo now ofter the service it tops out at 62 mph on the speedp.

Any ideas?

I'd check your New Belt adjustment.

speedo may be off too, my brute is 6 mph slower than what my speedo says, i tested it with both a radar gun and gps.

So would I the stealer may have "adjusted" your clutches to "align" the belt but you may have been faster the "old" way.(thats why I tell them NOT to touch my clutches on my wheeler or my sled!!!)
