Gladius engine into curvy frame - what's involved?

[BigFootIsBlurry]

As per title really, is starting with a curvy frame and a complete gladius engine, ecu etc a'relatively' straight forward case of swapping certain bits over or would it need any custom fabrication etc?

Some must have done it, I just can't it.

[andrewsmith]

To my knowledge no. Not sure if the mounts are the same

You will also need the gladdy airbox, exhaust, TB's, dash and all the sensors (inc speedo, Gear position sensor, PAIR gubbins, air box sensors)

its a lot work for not a lot of gain IMO

[speedyandypandy]

Do it just because you can, maybe you'll be the worlds first.

It'll fit in the frame. essentially you'll be fitting a Pointy motor into a Curvy frame.

First thoughts:

If you want FI you'll need the Gladdy's entire fuel and ignition systems, most probably easier to use Gladdy loom and adapt to fit your lights etc, FI fuel pump is in Gladdy tank, so not easily arranged on Curvy.
Curvy tacho easy to drive off Gladdy front coil.
Mark One Eyeball Test suggests Gladdy airbox won't fit under curvy tank, most likely be easier to use a set of Curvy inlet rubbers and carbs.
Clutch cable is different - existing be a teeny bit longer, but might fit.
Standard Curvy exhaust will probably fit as there's no oil radiator.

What is point of that?


Should drop straight in just like pointy lump

Blank off the PAIR, pretend 2nd plug doesn't exist, swap rotor, stator, inlet rubbers, job's a good un.

Fair point
Sid and Yc are right on this one, i was looking the twin spark setup.

Going back ot OP what you think about doing the swap for

[BigFootIsBlurry]

Thanks for the responses guys. I was only looking at it as someone offered me an unfinished project. It sounds like its doable but probably beyond my abilities, which is what I thought really.

Thanks again folks.

With the help off a camera and the guru's on here you can do it I'm sure. Go on, be a daredevil.

pretend 2nd plug doesn't exist.

Thereby removing half of one of the benefits of the Gladius engine/FI system. The fuelling on the SVF engine is so much smoother than that of any SV and this is partly due to the twin plug set up. Junk that second plug and you may as well just find a pointy SV engine up to 2007 and fit that instead of wasting extra time getting a Gladius engine to fit.

If you're going to do it, do it properly, not a half-ar5ed bodge up

[yorkie_chris]

Nothing to do with the heavier flywheel then? (junk that straight off, the 1gen is noticeably peppier with the extra mass machined off!)

Or you could get twin-lead coils and hope the inductance is about right for the 1gen ICU.

I'd be curious to know whether there is actually any extra time in using gladius rather than 2gen engine.

[Lozzo]

Throttle bodies, mapping and a whole lot of other stuff contribute to getting the Gladius smoother. Stupidly, Suzuki only went and spent years and a few million much needed yen developing it, when they could just have asked here how to do it properly.

A million yen is only £8,000

I'd suggest the twin plug head is far more emissions driven than smoothness.

By smoothness are we talking NVH smoothness or throttle pickup "jerk" smoothness?

It's all about emission, to bad, I like both gen of SV, I don't like the gaydius, there I said it, but it's true. Nothing against gay people btw, just a figure of speech.

[Lozzo]

The engine feels more like a V4 than a V twin - they're actually far nicer than the SV to ride because of this, especially at low speeds and through tight corners and roundabouts. The 2012 V-Strom uses the same throttle bodies and motor and that's a damn sight nicer than the older models.

[yorkie_chris]

With the caveat that I haven't ridden one (maybe I should get a test ride :-P), I'd reckon that is down to mapping and the heavier flywheel smoothing things out.

The later SV's with the twin plug head don't feel much if any different to the single plug.
