70cc class Dyno day

[huskihl]

Any of them would work too.

462, dolmar 572

Got some fresh ported 461 pics from last night. Nuthin too fancy though



This is before port work

 

[Red97]

So the 462,500 are also that arrangement?

 

[Moparmyway]

Slab piston.
Transfers are like the 462

Pics?

Not seen any of the newer stihl....

Just for the discussion.

I'm not much help till I get home.

But am curious.

462

 

[huskihl]

So the 462,500 are also that arrangement?

462, 461, 500, 241, 661 are fed from the front, but the 462 and 500 have additional runners sealed to the lowers that feed from under the crank

 

[Red97]

Is that one a 462 I take it?

Mopar’s is a 462

500i case transfer pic. Base gasket is slid back 1/8”

 

[Red97]

That 500 is tight...

[huskihl]

What oil mix was used Kevin?

Me? In the 500?
Have to ask @Redfin. I borrowed his pic

I'm taking a nap, sure would be nice to see some discussion on 70cc class saws... gains, thoughts, theory etc.

70cc saws are heavy and unnecessary. I like 35-50. Can we dyno those? Maybe add in some moped and pit bike convo for filler

Doninator in both the 462 & 500i

Hmmm. It carboned up pretty good there on piston top. More than I would have expected.

The piston crown is on the one I shared. Don’t believe he’s running Dominator

Mopar didn’t post a pic of his crown. Pic your thinking of was Mike’s saw that John has. Mr. sausage just stole the pic.

Confused yet?

Done!

Except the pitbike part.

They would laugh us out of here if we cruise up on pit bikes...

 

[RI Chevy]

Wow. I'mma just gonna sit back and have another cold one.
I'm so cornfused...lol

 

[Red97]

So the 462 and the 572 share a similar transfer layout...?
