Thank the lord that beast was not upped to a 6 stroke or it would be dangerous with all that power.
-
I hope that they import these to my area soon. I am envious of you guys!! 5 Stroke...simply amazing. So much technology to catch up on!!
-
i saw that ad on craigs list yesterday.
i live close to santa rosa so i might go and see what the 5th stroke does.....it could be enjoyable, or just takes a little more money from your wallet.
-
I'm waiting for the twin cycinder 10 stroke.

I'm waiting for the twin cycinder 10 stroke.
Is that the 1100 cc one from England?
-
If that was just a normal B5 he would have paid around $6000 for it around here.
Getting that special 5th stroke obviously was an expensive extra which cost him $2500.00
I think I'll just stick with my old fashioned 4 stroke for now. :)
-
geez guys ... can't you read, that is a 2011 model BRITISH Enfield, not the ordinary Indian ones like the rest of us ride.
-
Oooooh! Are those Whitworth CCs then?
-
Lol.
-
Thanks for the fun post...I enjoy Craigslist, if not for just the idiotic postings..!

The Imperial centimeter is 10% smaller than its euro cousin.

;D ;D ;D ;D ;D ;D 5 stroke ;D ;D ;D ;D ;D

So it wasn't this 5-stroke engine then?

Well, they call it a 5 stroke but I would call it a compound 4 stroke engine.
It seems to be basically a conventional 2 cylinder, 4 stroke engine that delivers its exhaust to the low pressure 3rd cylinder much the same as the old 3 cylinder compound steam locomotives did.
With the 3 cylinder steam engines the two outer cylinders on either side of the locomotive operated normally with steam pressure delivered alternatly to the front and rear of the pistons.
On the exhaust strokes each "side" cylinder exhausted to a centrally located cylinder driving its piston back and forth. This extracted much of the remaining steam energy (pressure) to create more power.
This third cylinder exhausted thru the smoke stack venturi to create the air draft feeding the firebox.
All three cylinders used rods to connect their pistons to the drive axle just like this "5 cycle" engine does.

thats just a fancified version of the "twingle" discussed recently else where on here, there are several people using this technique right now
-
Nah, I used to own a twingle (sears allstate puch 250) it was a ported 2-stroke engine with 2 pistons and a channel (port) cut in the head between the two combustion chambers. The pistons traveled up-and-down 15 degrees apart, the rear piston was the intake and the front piston had the exhaust ports. The 2 spark plugs were fired from a common set of points. It used two 3 volt coils in series. (the bike was 6 volt). Essentially, it was a single cylinder 2 stroke engine with a barrier in between the intake and exhaust ports, so, it was more economical to run and IMO ran slightly smoother than an equivalent single piston engine. (due to the slight lope in the power delivery created by the offset phase pistons)
-
Here is another one. This one is 750 c.c.:

C'mon Kevin !!

That red bungy cord is good for another 3mph of top speed.

my doctoy says 1 more stroke might keep me off my bike

Ghostly looking abduction on the third picture

Hope he's not selling that "750cc" because its too much bike for him.

I have heard the 750cc B5 single can be a touch bothersome to kickstart.
-
I love the special sell it quick price. Only around $400 more then a new one in CA, :o
-
Its back, and its still 5 stroke:

Strictly speaking, a direct injection engine could be considered a 5 stroke, induction, compression, injection, ignition, exhaust.
But who cares ;)

Injection and Combustion aren't "strokes" or cycles. Injection is a separate process altogether that occurs during a stroke (usually near the end of compression stroke), as does combustion (usually begins in the end of the compression stroke and continues into the power stroke).
