OK.......tell it.
I wanna hear all about the GTG.
I wanna hear all about the GTG.
What exactly did you compare?
I was just into the local dealer this morning and I inquired about Husky 390's eating bearings. He confirmed that they were in fact having bearing problems and that he reccomends running that saw at 32:1. Kinda made me chuckle as about ten years ago I told the same guy I ran all my two cycle OPE at 32:1 and he thought I was crazy.
I also asked about the 562xp and he said he waited some time before ordering any because he had heard about problems. He also said that he has only had 1 issue with one and that it was an early saw purchased from another dealer. I must qualify that by saying a 60cc saw is kinda a bastard size up here for commercial use. Loggers start at the 372 and go up and the tree service guys run mostly 50cc saws paired with 70cc and up saws.

Performance and Production is what makes me smile.
I'd rather run the risk of replacing a bearing than leaving HP on the table by running too much oil. But that's just me.

Ive been runnin the dogballs out of my stock 241 other than a muffler mod with 32:1 and it runs just fine.
Am i doin it wrong ?

I think your jumping to conclusions by assuming more oil reduces HP. It appears it does with H1R in Redbulls saws, but that oil sucks and has a history of altering combustion. Even so, I am very supprised how bad of an effect it has. Wasn't it 25% IIRC?
There is peer reviewed research out there that suggests the opposite. They also run very low oil ratios in sports where very small differences in HP mean alot.
And when a bearing goes at full.load you will be replacing alot more than just the bearing..

If your happy and it works for you who's to argue with that?
I'm impressed with the 241c. Nice overpriced 40 cc saw. The 261 pretty much just sits now.

Probably....but are you ever doing it right?

Unwanted Riff Raff.
Dis was good when it was done.
Hedgerow's mdavlee 7900 "mutt" is a fast sob.
Plus bacon. Lots of bacon. Iowa is very bacon intensive. Should have tried a Wild Thing on 33.774:1 with bacon grease.

Nope. I'll continue to use 32:1 in everything. I think H1R is off the list now though.
I'm gonna jump in here and say that the H1R is just too thick......
I know when I wash it out of my measuring cup it takes several times to get it all out.
You should see Motul 800 2T Road Racing!!! It's far thicker yet!

I'll be staying with 32:1........just on the hunt from that "perfect" oil again.

vids done...
- Both saws first drained of oil and gas.
- same stihl bar oil
-same bar - maul and I both have tsumura 36's. Some debate on if use them both or just use one and switch over. Ended up using same bar and switching.
- air filter cleaned
- 1 new stihl RS chain for each saw.
- one small warm up cut in cotton wood prior to doing the 2 main cuts. Everyone involved was interested in making sure all the i's were dotted and t's crossed.
Muff modded 661 50:1 H1R went first. I was cutting.
log 1 - 22.4 sec , log 2 - 26.0 sec
bar switched to ported 661, new chain used
Ported 661 32:1 H1R - I was cutting
log 1 - 22.0 sec , log 2 - 26.0 sec
bar already on ported 661 so we decided to do back to back.
ported 661 32:1 H1R - Hedgerow cutting
log 1 - 21.4 sec , log 2 - 25.0 sec
bar switched to muff modded 661 50:1 H1R (switched back to other chain) - Hedgegrow cutting
log 1 - 22.4 sec , log 2 - 25.4 sec
Next,
Switched the ported 661 from 32:1 H1R to 40:1 H1R (performed reset)
note - this cut was done after the chain had been used for a number of cuts. Namely the cuts shown (and more) in the very next post.
19.4 sec
The saw ran 40:1 H1R for the rest of the day. About half a gallon. A few people who ran the saw throughout the day, noted that the saw seemed to get stronger as the day progressed.

Where was that guy on this thread that said Red Bull would loose by 30%? Where did he get that number from?
So what this tells me is that it is way more important to have the oil/fuel ratio correct for a particular saw than performance enhancements. Correct? I mean, spend $300 for a port job for .4 seconds of an increase? Wow. And I own almost all ported saws, but running at 43.6:1 and have been for years.
Ported saws do make a difference when they are not gargling in oil. IMO
So much for calling Red Bull crazy from Wisconsin lol.
