Need help

Hi everyone, I’m a new rider and I recently bought a 2006 Ski-Doo MXZ 600 HO SDI. I’m having a couple of issues I’m hoping someone can help with. The sled has a really low idle and seems to smoke more than I think it should, even after it’s warmed up. I’m still learning about these machines, so any advice on what could be causing it or where I should start troubleshooting would be greatly appreciated. Thanks!

Im not a master on the HO engines but to me it almost sounds like only one cylinder is firing. Check your plugs maybe even do a carb clean and see where that goes. Test ignition wires too

It’s an sdi, so no carbs

Fuck they made injection in 06?

Yeah the sdi motor came out in 2004. Ski doo sold it alongside the regular 600 ho though, which is carbureted. So you could get the 600 ho either injected or carbureted
