Strange thing is Ive ran 110/87 50/50 @ 32to1 with 800t and my 461 piston looked just like bwalkers picture but I was tuned upwards of 14500
I continue to tell my customers 32:1, no less than 40:1 with a full synthetic.So, if one were to believe the authors dyno tests, we would all be running 32/1 as a compromise between maximum power and protection. As I believe some of the builders are proponents of a 32/1 ratio, this seems further evidence that this ratio is a very good one. I for one intend to try it.
I cut for 5 hours a day. Subtract an hour for walking, swapping out chains, fueling up, wedging. So thats 4 hrs per day, 20 hrs per week, 1000 hrs per year. I run two tanks thru the saw in about an hour. Another way to figure it is by volume. I cut 1.3 million board feet last year. I average 1300bf per hour. Again, 1000 hrs. I could go on. We could figure it in gals of bar oil if you'd like. I can tell you approximately how many pulls you'll get out of recoil or how many rims I go thru or whatever. How many hours you'll get out of a bar or chain. Unless you have a different way of measuring time down there. I also know how many hours I put on my skidder and how many hours I put in on the job. If i could make money cutting 1.5 to 2.5 hours per day like your numbers come out that would be great. You gotta work a little harder than that tho. I need to run 7-8 tanks thru my 390 to make money for the day. My point in my first post was to illustrate from experience that oils and octane aren't all what they are cracked up to be. Its the mix and how you have it jetted as well as regular maintainence.the insides of the engine, your only doing around 400 to 600 hrs running a year if its a 90cc saw

Yes sir! Guys who cut for a living know. Im sure he will come back with a long drawn out answer.*Quote posted below
10 g per week is 40 tanks X
30min/20hours per week x 50 is
1000 hours
Split the differnce at 8 & 10 gal is
900 hours.
You know what that means?
That gives blitzer an additional 22
hours per week to bake cookies.
Lol (inside joke...sort of)
*EDIT IN
To answer blitzer's ?
The top end is always immaculate
and can be put right on to 'your' new saw...use the new ring obviously
Boy's gotta run a little more that 18 per week to stump the Boaster Ha ha
Im interested in knowing more about the 927 oil. How dirty does it burn?
927 burnt clean for me. It was high load milling. I can get super techniplate to burn clean as well milling. Never ran the BenolQuestion to mind. Will Klotz castor oil protect better than r50?
You're getting less fuel, so you'll need to go richer.So if a guy switches from 50/1 to 32/1, when I retune, am I looking to go richer or leaner ?
Its never not worked well for me.So, if one were to believe the authors dyno tests, we would all be running 32/1 as a compromise between maximum power and protection.

Also some oils like H1R and marine oils in general, which have a higher percentage of heavy oils due to the high load outboards are operated under, can and will influence combustion negatively requiring jetting adjustments.You're getting less fuel, so you'll need to go richer.

I bet you go through a lot of melted boots with a pipe that hot ,blue to the stinger is pretty lean .Also some oils like H1R and marine oils in general, which have a higher percentage of heavy oils due to the high load outboards are operated under, can and will influence combustion negatively requiring jetting adjustments.
To me a good oil burns cleanly and has minimal effects on combustion. Film strength is a bunch of gack, especially with a low tech saw motor.
With that said with my bikes I will run a castor syn blend when going to the dunes as it makes me feel better given the very high load and since your essentially wide open all day long. My exhaust actually turns blue all the way to the stinger when duning. Then again your talking a 250cc bike making 50+ HP and a 500 making 60+ HP.
Boots are leather line in the inside of the leg. I always increase the main jet two sizes when duning, so it's not lean. This particular bike falls on its face when it's lean on the main jet and it also detonates very easily. As such if your tetering on the edge it's apparent.I bet you go through a lot of melted boots with a pipe that hot ,blue to the stinger is pretty lean .

I was just using my fuel usage times with my 660 which is around 15 minutes a litre WOT then I added 20% if he has got a more fuel efficient model.*Quote posted below

I do cut & sawmill timber for a living, time yourself for a tank of fuel WOT & you will discover why you're over estimating.Yes sir! Guys who cut for a living know. Im sure he will come back with a long drawn out answer.
