3.4 oz less. There's another 3/4 of a pound somewhere! The only aluminum bolts I've found on it are the case bolts. Every other bolt I've checked is steel.

They really did shave a LOT of cooling fins off this thing!
Porting looks identical. I will degree it after doing my the machine work. Squish is about .036". I'm putting a .020" popup on it and dropping the squish down under .020".
So the porting is identical but these are supposed to have more power than the original, no? So where do they derive the extra power from?
Here's a cold start after setting since last night.
Here are the very first cuts.
That saw is a runner stock, so I expect it to haul once you've worked your magic on it
Bone stock, 13" Ash cant.
As mentioned earlier, stock squish was .036". I turned a .020" popup on the piston and set squish to .018". That means it should have close to 2° lower exhaust and 4° lower intake. Port timing is currently as follows:
Exhaust 106°
Transfers 122°
Intake 78°
The exhaust and transfers are within 1° of the previous version and the intake is 3° lower...maybe. I'm not sure if the previous numbers were before or after machine work.
Previous numbers were as follows:
Exhaust 107°
Transfers 121°
Intake 75°
Exhaust 106°
Transfers 122°

The transfers on these are significantly angled. They actually start opening on the intake side at 122°, but aren't fully open on the exhaust side until 135°! All 261s are like this though. I just thought I'd point that out.
Here it is after only a muffler mod. Throttle response is improved and torque got a nice boost. It lugs much better under heavy load.
When are we going to see some aluminum shavings?
She's all back together and done. It fired up and runs perfectly. I'm anxious to get it back in the wood tomorrow! I'll be doing comparisons with the 346XP and MS241C. I also hope to run 63PS on all three of them.When are we going to see some aluminum shavings?
So don't buy the 241 yet.........
You can buy mine
PM sent.You can buy mine
You forgetting something?You can buy mine
You're right, I did. I was thinking you were only interested in the 261.You forgetting something?
