Gladius engine into curvy frame - what's involved? - SV650.org

BigFootIsBlurry · 27-08-12, 06:44 PM

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.

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

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

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.

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

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.
