Back in in 1986 it tried to build the hottest 090 ever built,absolutely no limits. I spent many months,lots of effort,money and sweat building it,to compete in HOT SAW-under 140cc.(According to rules in B.C. Canada then.) The hardest part was competing against the race go-kart race engines used by most logger's sports Pro's at the time. In several competitions I beat most of the go-kart engines,except Ron Hartil's Comet rotary valve kart race engine,that was hopeless.
Some specs on this 090 are:
-Billet Aluminum cyl. head,special comb. chamber,210 psi compression
-Full race porting,5 transfer ports,7 windows in lightened piston,reed valve assembly from motoX engine.
-Monstrous carb,(Mikuni),equivalent of Tillotson HR,from 440 snowmobile engine(11/2"-2" bore)
-modified and welded crank
-Lightwieght alum. flywheel and electronic ignition fro smaller model Stihl
-Race pipe designed for 12,500 toque peak
-14,500 rpm limit set before competition

It was an exciting beast to run!

I eventually sold it to a collector in the U.S.A.
I'll try to put some photos,hope they work...View attachment 189958
 
That one crude old Polaroid photo,was from a contest,in Smithers B.C.,28" log,my first contest with the saw,I knew nothing about chain then.I had the wrong chain,had it filed totally wrong,but I won with brute power,I got a Silver trophy,$100 bill and a bottle of whiskey for that one!
That was a big log,saw had to work hard.
 
The thing to understand is that professional Logger's Sports competitors will pay anything to have a winning saw,they usually have unlimited factory money behind them.They are gonna go around the country to all the events and will do anything to win.
That's not like the rest of us looking to win a local event or whoop our arch-enemies ass,whoever we detest locally.
Then it comes to a contest of best we can do within "SANE' money limits. Ingenuity wins sometimes.I've seen so many times where one guy will do just a little more to beat his neighbor
Basically it all comes down to your money or ingenuity.Even more,your practice,and your chain.
So whattya gonna do?
Many choices,I LOVE watching the results....
Fastest saw,fast guy,wicked chain??? Any one can win and I love watching "arch-enemies" competing. It's funny as hell.
That's why our local stuff is SOOO good to watch.
I was just in a thread here here where 2 guys were burning hatred,and exciting as hell to watch next time! This is our sport!

I had my competition at work,a race against another mechanic,a stock 038 Stihl against a 670 Jonsered,both new,stock saws.We could sharpen a stock chain on them and race thru the log at the end of the day. I killed him,I did 2 cuts where his Jonsered only did one,but he round filed and I square filed.I killed him,although saws were same power.
 
Mark figured out how to make us some race chain, it makes a huge difference.
Makes the other boys nervous when we show up. They wonder what we got this year
 
I here ya. Still would not part with that. I tried my a$$ off to get a dolmar 166 western that was modded about like yours about 15 years ago. It was the saw to beat at the woodsmans in Boonville NY along time ago. Not getting the saw has inspired me to build my own ugly cooky cutter.
 
I have a few modded work saws that I run. As far as a full race saw goes I am still keeping my eyes open. I have a 2100 husky but I dont know if i want to go that far with it. Thinking about a bike saw build.
 
Nice, I have a 2100, hopefully I can get together with trappermike and get it built right.
Then I will have something to justify the drive to tupperlake and boonville.
