Stihl MS500i

[markds2]

only muffler modded in the video its been ported by @huskihl and was ran by some at his gtg

only time mason ran the 500i was at the ct gtg before either of the 2 500i that was there was broken in
but some think they know all about all

Nothing wrong with how that goes pulling that 36inch bar! Question for @huskihl or @Mastermind can you port a saw just with the cylinder (I'm thinking of shipping costs) or do you need the bottom end as well (to time it correctly)?

If I had a case here I could do it. But I don’t, and I don’t have any 500i on the books right now

i could send mine to help

Ok...What sort of gains did you manage to make porting the 500i?

Seems like it was about 25% or so.

That's very generous of you Dall.

They shoulda put the 462 filter setup on the 500i and stronger AV mounts. The AV is rather floppy on a 500i compared to other offerings imho. I probably wouldn’t run longer than a 28” on it with that AV, which is about right for a saw that size anyway. It’s not a 90cc saw in long bar capability. Just something for the OP to take into consideration.

I ran the saw with a maxflo never made a difference on richness. I also stiffened the av with rubber bushings

Wow, that's substantial for a saw that is already powerful for its displacement!

Can you tell me what you use for fuel? The minimum Octane here in NZ is 91 and none of our fuel has any Ethanol. 98 Octane is readily available at the pump

 

[markds2]

My thoughts are that if you use a higher octane fuel that doesn't burn as fast that it might run slightly leaner?

@huskihl can you let me know when you do?

 

[HYPERSAWS]

I know you ported yours, but how did you like it stock? You had problems with it running rich didn't you?

I think it runs good stock, but there is always something to tinker with

We use 91 octane non ethanol

I think it would still run just as rich it's getting the same amount of fuel

I have only run 500i's stock at GTGs, but I have 2 ported 462's. If you did not have a 90 cc saw I may have a different opinion, but I think a 462 would better bridge the gap between a 50 cc and 90 cc saw, any you can get one ported through Randy!

 

[huskihl]

Yep will do

But what if not all that fuel is burning?

I'd definitely be getting a 500i through Randy if he could get them, I just think a 500i would be better with 28-inch bar in very hard wood compared to the 462.

Definitely

Dont keep speculating. Get ahold of one and run it the way you want and then make your decisions.
