572xpg vs 500i

[Red97]

Just waiting on the 462 now.

 

[Lightning Performance]

If all works out as planned.

Monday

572, 500i, 462, 7310 all going on the dyno. Bone stock less than 1 tank through any.

Nice lineup
Can you sneak a Dolkita 73xx or 79xx in there to round out the crowd? Just a thought

I remember reading the 500i didnt get full power (limited by "computer") until it had 10 tanks through it.

What I dont remember if that was speculation or if it was a fact.

Can anyone comment on that? Or did I dream it all up?

I have heard the same thing about the 572, owners report they really come to life after 10-15 tanks.

That poor echo don't look so purdy sitting between a 500i & 572xp...I still would love to run one, for a day.

Seems like all them wake up to a point but as far as a program in the 500i I wouldn’t know. All I know is the tree service said at some point in that first couple weeks of use it woke up. That saw has 111 1/4 hours on it now and been muffler modded since day one.

Some guy on the fake book was yapping about all the 500’s failing in the states and he wouldn’t be in any hurry to buy one. I asked him how many he knew of personally? Nothing but crickets

I know of 4.
1 lasted a week. Oil pump went out.
2 had hot start problems first day.
1 wouldn't start out of the box.

Ok, not saying no issues but way it sounded he was talking saws blowing more than oil pump and hot start issues. Did the ones starting hard get hooked to and mdg1 and reset done? Did it fix them if they did get a reset?

When it comes to the hot start issue, some of that may be coming from guys over using the primer. I have found even hours after the saw was last ran, priming is not needed, and if you do prime the saw it will take a lot more to start the saw than the one or two pulls if you don't. I actually unintentionally started my 500i by just giving the saw a halfhearted 1/4 pull after inspection when I first got the saw, it was hours after it last ran.

I am not sure if they ever restarted... stihls own manual/video says prime 8 times when hot.

 

[andyshine77]

NO! that is wrong, only when cold. My dealer and I had a talk about that. That would be really annoying.

 

[Red97]

I sure hope mine starts. I better check that....

 

[andyshine77]

Out of curiosity, I just went and started my 500i without priming, it's been sitting for over a week. It took six pulls to fire and three more to stay running.

 

[andyshine77]

Now that may not be great for the pump or what not, I recommend priming the saw the first start of the day, after that I wouldn't bother.

Way I understand it is the primer is just a purge primer like on a weed whip can’t flood them with it just to get fuel pressure at injectiot

Should work that way, but some have said with a warm saw it made them harder to start. It shouldn't but it seems to, maybe when you hit the primer, the system thinks OK the saw is cold and shoots in too much fuel? Just a thought.

 

[lehman live edge slab]

No idea but no stored energy in saw sitting shut off I don’t think. Battery less efi on a sled takes the first one or two pulls to prime and set the injection for a cold start. So they won’t start first pull cold because computer needs enough power to think on first ones. I was just assuming this saw works similar but might be wrong.

 

[andyshine77]

The system definitely stores settings, the Mtronic system does as well.

 

[Red97]

This was what I seen.

Mine started 3rd pull and stayed running after priming till I seen fuel.
