getting my cat to purr!

ok i just bought my first sled over the weekend, 87 cat jag 440, so today i worked on it cleaning and adjusting and greaseing the track, and just doing general maintnaince, and learning as i go, i know this sled is older but its in great shape with only 1200 miles, looks more like a 97,buy the time im done making it very reliable ill have less than a $1,000 in it, so its just another toy for me! i even got underneath and painted the rear suspention with rust preventive paint , were rust was starting, now i need to change out belts, change the chaincase oil, and new brake pads, and new wearbars, i also need to change out the plugs too, then this cat will really purr, also i ride dirtbikes and use synthetic 2 stroke oil, is this stuff good for my injection on this cat? or should i just run A.C. injection oil?, i was working on my sled out side it was like 55 here today, but when it does snow i wanna be ready!
