2016年1月3日 · My question, does anyone have first hand experience with a F33? I read that TBO is around a 1000 hours, compared to 300 on a Rotax 447, plus i've read that all 2 strokes are prone to stop running, especially during idle.

2015年3月16日 · In the '70s I grew up with 2-stroke road and dirt bikes, and found those (Yam and Zuki) to be strong and reliable, although smoky. Plugs fouled regularly, and exhaust ports needed to be cleaned now and then, but sooo easy to work on, not a problem. Get the oil mix right and keep the revs inside the redline and everything worked fine.
