650/1000 conversion

Well EXACTLY, that's the third version of the 650 motor and they're still screwing up So why is it so outlandish to think the first gen motor wasn't a screwed up 650 rather than a screwed up 400? Either way, they screwed up just the same.

I suppose at the end of the day all I'm saying is that there's stuff in there that can point either way, but none of it's conclusive, everything can be explained at least 2 wats. On the other hand Suzuki say it was joint developed, but they're unreliable because that's EXACTLY what you'd say if it was just a bored and stroked 400, and you thought people might worry about reliability. So I think we just don't know.

I know the crank pin isn't the same size, but that's kind of by the by... And though the engine doesn't have a 30% overbuild in it, it's not bang on the bleeding edge either. Lots of engines can't be tuned to 30% over without reliability issues, and the SV engine probably wasn't designed with major tuning in mind, not like a race rep where they know it'll go supersporting, or whatever. If you look at it as a race-base engine then you'd expect it to be stronger than it is but if you think of it as a commuter/streetbike engine, it doesn't need as much headroom.

only thing that was changed to up 30% is crank and bore(and heads to match bore).and reliability of 400 went down the drain
oil problem,crank problem,cases problem,tranny problem,cylinder problem,crank bearing problem....all this happens to stock motors,just more offten with built 650 on track.
so,if it is like you said designed with 650 on mind they screwed up even more
regardless of all problems it is still great little bike.

Ooooooiiii!

Northy & Zadar, this is interesting, but helps our friend with his non-sparking SV1000, not even the tiniest bit!

Through the mists of time I take you back to page 2 or so:

The crank sensor will almost certainly feed a signal to the ECU, which will feed a signal to the coils. Places to look for a manual include using bit-torrent type clients. There used to be down loadable PDF versions of all 650 manuals on this site, but the data usage got too much so they were seeded to bit-torrent. Sometimes you can only find the manual you want in Spanish or similar, but for the wiring diagram this is less likely to be a problem.

Best of luck

Oh yeah that's what this thread was on about

If the coils aren't even getting live feed then it's not a crank pickup problem, maybe interlock circuit with sidestand switch n stuff?

I'm still trying to work out the "why"

Didnt Mr Suzuki build a frame to take an SV1000 lump ?

sorry
that is correct.signal for coils goes from crank sensor to ECU and than coils.is he getting power to other side of coil?
