04 Mt. Cat Problem

[windriver_rider86]

I am riding an 04 Mt cat 600. It is lugging out in the bottom end but runs great above 5000 rpm. I cleaned the power valves and didn't see a change. Any ideas would be helpful. Thanks

you may want to ck for a broken or sacked primary spring. jmo

Could be clutching. Try asking the boys in the Arctic Cat fourm.

Check primary spring. Also check the weights to make sure they don't have a flat spot on them. My wifes '01 Mtn cat had that problem.
Of course check the belt.

Try a different belt. I've had that problem before.

could be bad throttle. Test it by rev up the engine same time you apply little pressure downward and if engine drops some rpms then that is the problem. It did that on my 98 ZR600.
