90 Degree V-Twin: Firing Order of 270/450?

I tell you Dusty, the answer is ALWAYS bacon.  Accept that.  Embrace it.  Then all mysteries of life willl be revealed.

 Yeah , except I really don't like bacon , so what then ?

Well, for those with religious, personal taste, or too many reads of "Charlotte"s Web" that make bacon eating distasteful, there is an alternative fact available.  That answer is "C".   

But you knew that, or you wouldn't have made it this far.

I think I may have read somewhere once* that the bacon gene is either cultured or dies in the early years, like the yearning to push buttons, or disassembling stuff.  Some kids get it, some don't.  Like the natural attraction to the edge of high places and cat boxes, all babies are born with the natural expectation to like bacon, but for some sad souls, like the little boy surrounded by wonderful machines who grows up and goes liberal arts instead of vocational science, the gene does not exist.  For them, more the pity.  For me, more BACON!! 


* no, I didn't.

so what do you cook at 9 am?  what about midnite? 

[redhawk47]

you're kidding, I take it.   

And I am still clueless about the 180 degree interval.

Kidding about what?

What 180 degree interval? There is none on the Moto Guzzi twin. Are you referring to 450 - 270 = 180 ? That is not a valid equation because the 450 degrees is not from the initial starting point. It is from the 270 degree point. The proper equation is 450 + 270 = 720 (2 revolutions of the crank).

We are in total agreement.  I posted the same thing several times earlier in this thread...... or you could say the firing interval is 9AM and Midnight.   

the 180 business was posted by someone else and never clarified..... it's not possible with the geometry of a 90 degree V twin

Yeah , with all due respect to the other participants on this thread , how many of you guys are engineers ? Well , besides Kirby .

Could be any one of us Dusty..

[oldbike54]

Could be any one of us Dusty..

 That explains alot , a carpenter would just set the valves and the TPS , check the tires , and ride the dang thing

I've wondered why the cylinders were numbered right to left ( from the seat) rather than the standard left to right. The answer is simple and it dawned on my thick head as I was looking at an engine on the bench: front to back, another standard.

From the seating position, they ARE numbered left to right.

can you do dovetail joint? I always find it fascinating

[oldbike54]

 Sure , not much call for that now though .

WOW!  Sure wouldn't want to see the thread if we were discussing something with a more complicated firing order, like a flat-plane 60 degree V-8.  Or, an 18 cylinder radial.  Or, a 9 cylinder rotary.....

Anyways, I'll take an AR10 over an M14 ANY day!

M14 anytime! (the Vedeneyev M14P  9 cyl radial...)

[Delta425]

M14 anytime! (the Vedeneyev M14P  9 cyl radial...)

M14 because you like things that don't work when dirty!?  When in the Corps we mud tested AKMs, M14s, M16s (same architecture as AR10/AR15), M1 Garands, FNALs and a few others.  Bet you can't guess which type worked EVERY time and all the rest failed a lot?

[Muzz]

The AK.

[Delta425]

The AK.

Uh... No.  It's bolt is just as open to the elements as an M1 Garand or an M14 or an FN.

[Delta425]

Uh... No.  It's bolt is just as open to the elements as an M1 Garand or an M14 or an FN.

Well, almost as open.  The AR15/M16 worked every time.  The AKM and FN FAL were second and the M14/M1 Garands NEVER worked in the mud test.
