Four stroke oil change

purchased my first four stroke engine for a very good friend to ride, getting ready to change oil and it says you have to purge the air out of system, I have read posts on other sites regarding this, was wondering if completely necessary, have seen people say both ways, just wondering thoughts, personal experiences.

this is on a Suzuki 1100cc, I thought it had to be done on other engines as well, or was at least recommended to anyways since it is a dry sump system, and as I posted I have read where people do it and people don't and was just hoping for some input. I would think it would self bleed but again first 4 stroke snowmobile so unfamiliar.

It’s an 1100 Cat Crosstour 4s so Idk either but was not an issue with Doo and Yamaha 4s engines.
its not an issue, its part of oil change process on the Suzuki engine, just wondering if completely necessary or not to do, again read it both ways, hoping someone would chime in that has one if they do it or not.

Wrong word I guess not part of the process with doo and Yamaha 4s oil change. Cat maybe Idk. Jim Andros might know PM him.

I had the XF1100 turbo and never did anything to purge out the air. Changing the oil on that engine is a pain in the arse though. Filter is almost unreachable in the nose, and the oil drain is inside the foot well. Have fun!

I don't remember purging the 1st generation 1100s (F & Jaguar chassis) but it almost rings a bell in the 2012 & later with the oil reservoir being built into the chain case. That was just when I was getting out of business. Sorry I can't help.
