After the rebuild tuned by dolmar dealer was 13000rpm.
Tuned by me after I learnd from you guys about 4 stroking and 2 stroke in the cut was about 11500rpm and in the cut was about 8000-8300 rpm!


Sounds way too low (rich) to me - if 11,500 is WOT out of wood?

is it still leaning out in the cut? my 5105 has a nice burble at 13300ish. rev limiter starts complaining at right around 13900ish.

It is the performance in wood that is most important I think. Optimal RPM's is different on each saw. Setting after a specific top rpm is often misleading and can be a disadvantage.
If it holds 9000 in wood and perform correct I think it sounds pretty good.

The sound is good in wood at around 9000 rpm in wood and according to the factory the saw makes maximum power.At full trothel makes a little burbel and is around 12500rpm. :)

I was cutting some wood today and I increase the rpm at wott,around 13500 the tach went crazy.Its ok?
At 12500rpm  tach, and the chainsaw works fine.
The sound at 13500 - dont like it.

It has a rpm limiter in the coil that is set at 13500 rpm. When it goes into coil limitation the tachometer will go nuts.

i've seen some that like to start cutting in at well below the '13500' they're rated for. the 5105 i bought new was cutting the spark at 12600 no load. most i've seen are around 13000ish flat.
i've also encountered a few that go well above the stated limit. same part number, very close to same build dates and want to rev well into the 14's, when they were supposed to top at the newer 13500.
i was lucky that weagant farm supply had an older 5100 unlimited coil sitting on the shelf me. still, anything over 13700 is getting lean on mine. some i've only been able to tune them to just barely over 13000 to where they sound maxed out.
