Well, guys i picked up a stihl 070 and just got a chance to try it out today and what a huge disappointment. I swear a ms460 would out cut it all day long. I only had a 36" bar on it with hopes of putting on a bigger one. Tried noodling a 20" piece of wood and didnt go so well. Well after using today i may have to go to a 20" bar lol. Thinking of putting a 090 piston and cylinder on it. Thoughts?

These are a low RPM saw not high speed laser beams but they will pull a big old chain in a cut and are dependable. Tune it for the mix you are using and keep the chain sharp.
They're turds in stock form, factory choked them pretty bad for longevity. They wake up a ton from mods, here's a dyno result from my ported 090 @12hp. Come to think of it, damn thing can be pushed further. But doubt it'll hold up

My 070 pulled a 36" bar ok, but that was about it. I tried a 60" bar and it smoked the 3 shoe clutch. If you put an 090 piston/cylinder on it, your gonna want the 6 shoe 090 clutch, then your golden. And no power issue then. Maybe run an 8 pin sprocket for speed.
Ordered AM 090AV Piston/Cylinder kit. Will be interesting to see/feel the difference
Is it a genuine 070 or chinese.
Is the governor disabled and tuned like one would any saw cleans up in the cut.
You can't get an aftermarket 090 clutch only oem dig deep if ya want one $$

They are about $250
Yeah they run like turd if tuned rich or even close to factory settings. Runs alot better when leaned up a little with governor disabled
It’s is a Chinese one. Thought it was real until looked a little closer after buying. Only paid 350.00 so not out much.
Words can't describe how awful an 090/070 sounds and dismissal in performance they are with the governor functioning set to factory specs from the "manual" lolYeah they run like turd if tuned rich or even close to factory settings. Runs alot better when leaned up a little with governor disabled
1st thing the old timer cutters did with a new 090 was disable the governor and tune the saw then run em for a few thousand hrs then sum...
ok. How do i disable the governor?

Thanks for manual
Would i remove the entire thing including linkage or just remove the cable?

Try the cable first...and if you like the way it runs, then all of it...I wont be doing that to my 070. I like the way mine cuts with a 24 inch bar.
Lol I have nothing to lose. I will wait till 090 cylinder kit comes in first to try. Thx

As noted by others the 070 is not a speed demon. I have zero doubt the 462 will outcut it with a short bar. Now try the same comparison using a 36" bar with .404 chain in 30 " wood. Use the same bar/chain on each saw in the same wood and then see how they compare.
When working properly, the governor keeps the saw at 8000 rpm in or out of wood. It does run like a turd but it will settle down into a steady 2stroke stuccato in wood at 8000 rpm. Have to have a little finesse when running like that to keep it loaded just right. When I tune to clean up in wood on the saw w/o the governor I think max rpm is around 11,500 rpm and that equates to 9500 rpm in the wood. Cuts like a mother for ya.

I would like to run one and compare it to the pioneer super 620.
No need to remove anything you can't remove the linkage will be nothing to hold the choke plate open when the saw is running it's a stupid design all the govenor does is pull the choke on.
just wind the spring up and clip it back in so it has enough tension that the flap doesn't move.
Then tune the saw like any saw if ya want it fat tune it fat.
