09 XP, MXZ Renegade X 800R.
1st ride of the year. Sled has always been an extremely strong runner, only has 1640kms.

Sled will only idle on one cylinder and sometimes won't idle at all. Flip the choke at idle and you can hear the other cylinder light up. Exhaust temps are far cooler on PTO side. Has a bad bog when coming off idle. When it gets going it pulls normal until I get off the gas for a few seconds, then bogs again when I get back on it.
Plugs have some deposits but look the right color on electrode.

Changed plugs, checked compression and have even 130 psi +/- each side.

Carbs next? Perhaps a plugged pilot jet?

Plugged pilot jet ( idle to bottom of mid jet) it's a real small hoke and easy to plug up

Fixed it. Half a can of Sea Foam in the tank, took a 15 minute ride and good as new. Hard to believe but it is what it is.
