XC 500 low throttle bog

Have a 2000 XC500. Just bought in spring, today I put a new fuel filter in and started her up to run for a bit. Starts great idles great and seems to get up and go good. I did notice one thing. clutch engaged at around 4000 rpm, if I lightly engaged it so track was barely moving and then punched it, it would seem to bog for a second and then go, it also backfired a few times. This is all with the back jacked up. Gas is fresh, and compression is 120 in both cylinders. It hasn't been run in a year besides this summer when I popped her off a few times. I know it needs to get and go but just wondering if there is something I should check into. Thanks

Wait til the snow falls and see how the sled actually performs then. Make sure the carbs are cleaned, throttle isnt too loose - if all checked out fine. You may be all set. WL

I would toss in a half can of SeaFoam on that first ride, too. Often, that hesitation is a lean bog and can be due to varnish built up in the pilot jet or fuel passages to the pilot jet. SeaFoam will help take that out and may be all you need.

Cleaning the carbs like WL said is always a good thing to do for that reason.
