honda cvcc motor in a suzuki?

[chompper]

My brother keeps trying to tell me that my GS850G motor is a honda CVCC motor and when he couldnt find a picture of it said it was still a honda motor is it true does anyone out there know?

Well, that's just BS.
The original CVCC was a special engine with a tiny extra extra intake valve designed to let in a little bit of a very rich mixture, which allowed the rest of the intake to be a much leaner mixture. The small shot of rich stopped detonation even though the overall mixture was very lean.

I have never seen such a thing on a Suzuki GS.

From Wikipedia:

Honda CVCC engines have normal inlet and exhaust valves, plus a small auxiliary inlet valve which provides a relatively rich air / fuel mixture to a volume near the spark plug. The remaining air / fuel charge, drawn into the cylinder through the main inlet valve is leaner than normal. The volume near the spark plug is contained by a small perforated metal plate. Upon ignition flame fronts emerge from the perforations and ignite the remainder of the air / fuel charge. The remaining engine cycle is as per a standard four stroke engine.

This combination of a rich mixture near the spark plug, and a lean mixture in the cylinder allowed stable running, yet complete combustion of fuel, thus reducing CO (carbon monoxide) and hydrocarbon emissions.

The 850 is definitely not a Honda CVCC motor...

Clip your brother round the ear for us please, and tell him not to blaspheme...

[TeamDar]

Your brother sounds like a jerk!

[Nessism]

Not a jerk, an idiot.

[tkent02]

Not a jerk, an idiot.

Not an idiot, just sadly misinformed.

Well he might be a misinformed idiot.

I think we have a new record-holder in the "Weirdest GS Question Ever" category.

He says the 1976

he says the original cvcc pre-civic and he says the block is the same. and i have looked at pictures of an old honda 750 m/c and the engines look surprisingly similar. i personally dont think the GS850 has a honda engine but my bro says the block is the same. I personally dont know im not a honda guy he used to work for honda as a tech. he says "the upper half is changed in the m/c to allow for air cooling" i personally would really like to get some diffinitive way to prove him wrong anyone have a pic or know where i can get a pic of the original cvcc engine at least the block anyway. im really gettin sick of him tellin me my SUZUKI has a honda engine he got honda on the brain i think

Your brother is just flat-a$$ed wrong. Did Suzuki have them recast the bottom end for the tranny and clutch? How about the stator out on one end of the crank and ignition on the other? The original GS was closer to the Kawasaki KZ engine than anything else.

[GregT]

OK I'm old enough to remember the motor he's talking about,I think.
Pre Civic the first real car Honda did was the 1300 - front wheel drive,transverse engine and fan cooled. SOHC - which was laid out just like the CB750. Very nice die casting exercise - state of the art at the time and done by the CB750 design team I believe.
Copious finning and nice fan shrouds.
But - plain bearing crank, SOHC, Camchain on the end of the crank.
And it was not CVCC cylinder head.
How does this look like a Suzuki roller bearing DOHC motor ?

I repeat, clip him round the ear... Brothers are like that.

A good friend had a 1300 - and raced it here. It was the rare high performance version with 4 CV carbs - and would murder a 1275 Mini Cooper in a straight line.
