    Default Stihl 500i

    Waiting with bated breath for this one.
    My dealer has offered me the first one he gets to test.

    It has more power than a MS661 and weighs only slightly more than a MS462.

    They sure make it easy for this logger to get old.

    The link shows the comparison between the different models in weight and power.

    Reminds me of Robert Palmer's hit single, Simply Irresistible.

    Even at 2K.

    Thanks Stig.

    Looks absolutely beautiful!!
    Pricy but likely well worth it. I'm excited to see what it can lead to. Like if the technology will carry over and influence other saws in the next decade. If they can make an 80cc saw outcut a 90+ cc then it might be reasonable to one day see an <40 cc top handle that can hang with or outcut a 50cc.
    Sorry I tend to daydream.
    I hope it's made available in the US. I'm eager to read reviews after it sees a couple years of hard use.

    Website says less power than 661 and 660. A ported 70cc saw would be competition for it in both weight and power. I wonder how much room for improvement there is in porting a 500i, might not be much if any, and that's a good thing in a way. It holds a tiny bit more gas than a 441, but less oil (I don't like that, I already feel Stihl tends toward too little oil much unlike Echo). Overall less fluid capacity for the CC's. So, smaller tanks save weight. They could be saving lots of weight in engine parts by strategically reducing material where it isn't needed.

    EDIT:

    They do claim a higher flow oiler (just watch you don't run out of oil before gas).

    Plunge cut guide sight line.

    Look at the crank case going up in the piston. Keeps crank case volume smaller for more efficient mix transfer. And it could help direct flow towards the ports. A big step in efficient 2 stroke tech.

    Looks interesting & I have seen a prototype being run. For someone like Stig, who does not run ported saws, I think it will be a big game changer
    To gain that which is worth having, it may be necessary to lose everything else.

    I’d like to see the rotary engine revisited.

    If it looks like I asked a question, but put a period, it's probably a question.
    Don't know why I'm question-mark challenged online. 😀 New Year's Resolution, better proof reading.

    Is the fuel the same, just no carb? Where do the weight savings come from. Why is this not been done, What's the breakthrough here. Cars lost their carbs years ago wh
