Tree Monkey 661

I think it's the small aluminum flywheel and placebo.

If you don't watch it sounds like a husky in the 661 videos

That 64/66 is hard to beat.

Maybe it's got Husky parts in it.... Lol [emoji6]

I see what you did there!

 

[tree monkey]

all ya want to talk about is the old out dated junk?

 

[MG2186]

Yup! If it's got it...it's got it, don't matter how out dated!

I will dispose of your outdated junk for you

I didnt ask about anything old or outdated ..........
I asked about transfer shape in the Redbull 661, are the roofs still splayed or flat ?
Do they open at the same time ?

A one word answer to each of those questions would put a smile on my ugly mug !!

Carefull, you might get a package with a bucket of stool for disposal

Yeh but the only difference in a 660 would be the big rod bearing. I think case capacity is the same.

Are the wrist pins the same and the difference in the bearing O.D. ? Are there 2 different wrist pin 064s?

 

[Gunn]

No Keith, wrist pins didn't vary in 064s

 

[Keith Gandy]

No Keith, wrist pins didn't vary in 064s

But the bigend bearing on the 064/ early 066 r the same but the later 066/660 are bigger? Then the diplacement of the cylinder on the 064/066 makes the difference instead of the 440/460 being in the smaller crankcase?

 

[Definitive Dave]

064/earliest 066 cases gotta have a smaller case capacity, unless there is some break in physics

I think it's the small aluminum flywheel

and placebo.

There is very convincing opinions on this : the 044/440 heavy flywheel is know to be the "key" for torque

Jay,
Any chance of weighing the two (small aluminum v plastic flywheel)
I'm betting the one with more A55 is the one with more "mass".
I'm seeing some "porting" of flywheels in the future.

 

[Deets066]

I'm not so sure about porting flywheels, but there might be a desired one over the other.

@tree monkey which flywheel is on your 64/66?

 

[Gunn]

064 flywheels didn't come in many variations, either one keyway or two.

 

[jmssaws]

I've got a set of 064, short 066, big bearing short 066,big bearing long 660 cases that I'll cc this week. Without cranks in them I bet there all the same.

 

[angelo c]

Do the coils interchange as well? .
Maybe it's a coil/ flywheel combo that's favorable.

 

[Gunn]

There's a few different combos, but they boil down to limited coil and flywheel combos or unlimited combos.

 

[jmssaws]

064 has more aggressive ignition timing and a flywheel that's half the size of a 066/660.
