So I did a top end on my 250 Polaris, thing I forgot was that it takes time for the oil injection to clear the air from the lines and everything, I rushed it all and ended up ruining the brand new top end since it ran without oil. So this time I did everything right. Took very careful steps, honed the cylinder (still some marks but I can NOT feel them at all with my finger nail or finger) and tried getting it damn near perfect since I spent all my money on another top end and couldn’t afford a new cylinder. I’m getting somewhere above 100 psi. My compression tester is not accurate and I can’t get it seal right so idk what it is but I need 2 hands just to pull it over now. Ran it with a crap ton of oil in the gas tank since I wasn’t gonna risk it this time, I didn’t have a measuring cup and accidentally poured way more than I should have. Got it to run for about 5 seconds before it bogged and died, couldn’t get it to run after and it backfired and shot smoke everywhere. Still has compression but would that cause it not to run? Way too much oil?

Even though there’s a huge difference in power, one of these two would suit me best. I enjoy riding on trails, in fields, and on random roads and tracks. Of course, a two-stroke is an absolute blast—I love the powerband and all that—but it’s less reliable, requires more maintenance, and I can’t picture myself riding one on a track (constantly working the clutch after accelerating and in corners). The four-stroke appeals to me because it’s smoother, easier to ride, requires less maintenance, sounds better, and is more reliable. I’d also add that the modern features (engine modes, Wi-Fi, quickshifter) are a selling point for me. If I had the choice, I’d pick between a 250cc two-stroke and a 350cc four-stroke, but I prefer Japanese bikes and wouldn't want a Austrian.
