I will be going to the GTG


So, T-minus 24hrs to the stock 661 vs ported 661 show down !!!!!!!!!!

should be interesting


bought a 100' roll of 3/8ths RS and a roll of .404 RS hopefully it shows up today as promised.

If so we can do some vids of various saws against various saws. ( Bringing all my bars. )
That sounds alright. Can you video it for us so we can se how slow a ported saw is with more oil. Thankyou looking forward to that vid
 
ok some of you wanted to see how much the tune changed going from 45:1 H1R to 32:1 on the 660.

Saw already had 45:1 in it so that is what I started with....




Then dumped out all the gas and refilled with 32:1 H1R. Started it, let it run for a bit, then did some wot revs then filled tank back up and did this vid.

So adjustment was quite a bit less than I thought. Like I said earlier it wasn't something I really paid attention to because it wasn't a lot and jump out at me like the 361 did.

 
I'm surprised to see it actually pick up 400-500 RPMs. Pretty cool. It definitely leans out the tune.

I'd expect just about any oil would lean it up that much going from 45:1 down to 32:1. Maybe not.

45:1 rpm high 13,300
32:1 rpm high 13,700


But to answer the original question - the H changed ..not very much!

other thoughts -

The 660 was very receptive to going to 32:1. While the 361 and 661 were not. Why I don't know.

That said, IMO the 660 liked 40:1 the best though. (out of 45:1 40:1 32:1)

I am not shocked with that oil..
 
I haven't noticed any change in years..smell, specs etc. The fact is its a very good oil regardless of who makes it.
I know Citgo produced it till maybe the last few years(IIRC in OK). In the past Chevron made it. It's always been a good oil.
I agree, it's one of the few oils i've always recommend, especially in stock saws.

I know you dissigre, but for all out protection R50 is the bee's knees, K2 is second on that list. Never cared for H1R.

So, what order would you rate them for all out protection ?
Just your particular preference .............

R50, 800 off road, K2, R2, H1R(I don't like it so much either), Lucas ............ and any other ones I missed ?

Going to be over 30+ people there to witness it. No one can say I fudged anything!

We are even buying gas there, tomorrow morning, same pump, etc etc blah blah blah

of course I'll video it.

I think he'll lose or it'll be very close at 32:1.

I think we'll then try 36:1 11% less oil so more on par with the rest of the oils out there with their solvents , which make up 5-20+% of the bottle.

See how that goes and maybe 40:1. I don't think past 40:1 is a good idea.

I think at 36:1 will be perfect for H1R and that is where the saw won't be bogged down any longer and then the ported saw will totally kick my muff modded's saw's azz. I think H1R is to pure by volume and I think you guys using it at 32:1 = using to much oil.

That's what I think. Could be totally wrong...and I don't care. We shall see.

I suggest you do the reset procedure with this new gas you are going to be running

I'm sure some of the caster oils will have advantages in the most extreme conditions, but that's not really going to happen in as saw.

R50
Motul 800
Silkolene pro 2 sx
K2
H1R is fine, I just didn't care for the tuning oddities, and it's one of the most expensive oils out there.

Out of the thinner oils

Yamalube
Motul 710
Stihl ultra
Never ran any Lucas, I'm sure it's decent oil, but I can't get over how watery thin it is.

Do you seriously think going from 32:1 to 36:1 is going to make the ported saw go from losing to kicking your rear? Seriously? It's stuff like this that makes you totally lose credibility, IMHO. That just craziness.
