Why do you suppose MoCo has never adopted off setting the rear cylinder like the Jap Vtwins. I used to ride a Yamaha Road Star and never had problems with an overly hot rear cylinder due , at least in part, to the rear cylider being slightly off set. Seems to me it would be an esy fix to this recurring problem.

 

Then it would not be a V twin

wtf, pray tell,would it be then?
when you get a chance look at a V-16, V-12, V-10, V-8, V-6 or V-4from above. Almost all have one bank of cylinders noticeably offset front to rear from the other bank, yet they are still V engines are they not?
In fact, look really really close at an HD "v-twin"with the cylinders off, you'll find a very minor offset to the cylinders because the rods cannot occupy the same space on the crankshaft.

 

Yeah, kinda my thinking too. It's still a V something or other. I didn't quite get that response from NCCOP???
Stills seems like a fix or at least a sorta fix for a hot rear cylinder. Anyway. I only ride it, I don't get a say into the design. Willie G, are you monitoring the board ;-).

 

I don't think it's an offset issue. More has to do with EPA forcing the MOCO to run lean. Just happens the rear cyl. is closer to your asssss.I don't see it as a show stopper, it a HOG and they are unique to all others on the planet. Ain't the fastest on the planet but it is the coolest on the planet, if you know what I mean. Justmy 2cents. Keep it real.

 

OK, point taken BUT the EPA says the Japs have to do the same and they don't have a hotter rear cylinder---so----????

 

If you offset the cylinders then you won't have the shake at idle that most of us love about the touring line. Think about it you currently have to big arsch heads that are directly in line with each other that causes the motor to vibrate as each head moves up/down.

That's part of the mystic.

The new PCIII allows you to adjust to front and read seperate whenyou dyno it. It is a EPA problem not the angle. The trick is to find someone who knows how to Dyno right.

 

Harley use's a single pin crankshaft which is narrower. Alot of the jap bikes use a dual or double pin crankshaft which is wider and the cylinders can be offset more. The single pin crank is where harley gets it's famous sound.

 

Ya know, that is a helluve good question.
I know, I know- water cooled and all that.But there's MotoGuzi and Victory- how they doin' it?
