The V-twin engine

[Owenski]

The V twin which suzuki use, is it the same one all through the years 99-present?
Meaning is it only the gubbins around the engine (obviously the carbs became and FI system) But are the engine mount locations etc are they all in the same place.

I prefer the riding postion of the Curvy and as a project Im fantasising about a little project build. Find the newest reg curvey frame I can find the newest suzuki vtwin I can and go from there. Building a custom bike it will take years to complete but the curvy is honestly the most comfortbale I've ever been on a bike.

Yeah the engine is the same but you need to swap the ancillaries. The thou is very different from the 650. Not sure about the gladys.

I don't see the point unless you know something about gladys that we don't. Apparently they made the crank heavier. Twin plug heads rob power on the new stuff.

[Owenski]

well in my little fantasy it'd be something that I'd be building now and keep for life as a little toy and so purely I'd want the lower milage not really new for the sake of new but just for wear.
Although your the bloke to ask; What about an re-built engine if an engine has a re-build, mechanically speaking does its previous milage become irrelivent?
Therefore could I make do with my existing engine if it was re-conditioned.

Depends what you replace. You know about fatigue?

Cases is irrelevant. Crank maybe better to go for a low mileage one. I've heard the 99 crank is the strongest but that's totally unsubstantiated.
Rods, again subject to fatigue.

Pistons, rings and bores wear. But not much. Same with valves and all seals and guides.

[Owenski]

Is fatigue what you showed my on that crank at yours? The microscopic wear caused by the tiny tiny particles of metal which float around in your oil? Or is that something toooooooootally different?

See I didnt even consider the option of buying the parts individually/replacing the ones which looked a bit ****. All the valves, seals etc I'd have thought would be replaced. I'd touch up the exterior but that'd be aesthetic only.

You'll be pleased to know that the little fantasy bike was a naked lol, oh and it has that exuast we were talking about. (dont wanna spill the beans on here in case its something your actually planning on doing).

Twin plug heads rob power on the new stuff.

Is that down to them retarding the ignition a lot? Im sure if that is the problem its not really down to the fact it is a twin spark but the fact that they screwed the ignition timing?

Normally twin spark gives better power.

All I base that on is someone did the same mods to a late model that they did to an early one and got less power. It's on the twin works forum somewhere.

[fastdruid]

Normally you'd twin-spark plug big twins where you have problems with incomplete combustion, has the side effect of better economy and more power.

Could be they compromised the head design to fit the extra plug and while they get better economy it is at the expense of the 'ideal' burn path or they have to fit smaller valves to fit the second plug. I'm just guessing though.

That was just f*cked from lack of oil

[Owenski]

That was is yeah, it had seized I remember you telling me now.
