4-stroke vs 2-stroke warm up time
I own a 1995 Polaris magnum 425 4X4 (4 stroke) and my brother owns a 1992 Polaris trail boss 250 2X4 (2 stroke). We also have two Polaris snowmobiles, a 1997 Polaris trail touring and a 1999 Indy 340 sport lite (both 2 strokes as well), and last but not least a 1992 Yamaha wave runner 650 (2 stroke).
I know people are always talking about letting the engine warm up before you use it. It makes sense with the four stroke engines because it lets the oil warm up and get in all the moving parts (i usually let my magnum warm up approx. 1 minute and go really easy on the throttle for the first little bit) but with 2 strokes there is no oil to warm up, so do they need time to warm up? It makes sense to let the metal parts warm up, but I always think of 4 strokes needing warm up time and 2 strokes needing less if any.
What are your opinions?
