This saw really dosnt shine until it's in huge wood. I lowered the squish on mine which boosted it up to a 175-180psi. Duel ported and tuned after the coil swap. Cant remember if its limited to 10 or 10500rpm stock. Mine is tuned nicely at 11500. I like it much better unrestricted.

The service manual says set the high screw to 8650, so port timing must be for the power band down low, higher rpm’s means tighter balancing tolerance for the rotating assembly and the heavy ass chain. How is the vibration at the high rpm?

Nice and smooth. I have I vid link I'll try and attach.

Hope this worked

Lumbering along, not even working, what happened to the beer gut.

 

[Chashowlett]

Sounds like 6-7k rpm though, I could be wrong. Some guy on here has audio monitoring device that can figure out the RPM by the tone and pitch of the recording analyzes,his name is on another one of my posts/videos,6100 Dolmar

Thats probably 9-10k and 8500 lugged down.

 

[Chashowlett]

Where’s this beer gut.? Look kinda famished to me

 

[Chashowlett]

Anyone ever try a harvester chain?

Taching at 11.5 WOT off load. Just meaning rev limit gone and not worried about. In cut I've never been successful getting reading because I'm alone and can't keep saw under load one handed. But yes 9-10 in 3ft wood is the range I get.

I remeber u tuned the saw to 12-12.2rpm, why you change that to 11.5?

As I went along and tested it changed. 12 sounded ok 4 stroking but once I cut in some bigger stuff it was lacking I backed it down and the power band in the cut came to life.

Splitpost did the same saw and at the same time. He discovered a lot things and I think he got more out of his without porting. If I remember he put in an 084 intake boot. I'd be curious his final numbers.

I’m happy just hearing mine idle

I belive he changed the intake boot (088) because he use the bigger 088 carb.
441 or 361 coil plus muff mod

You need a muff mod...
That Sound will make u more happy
