honda engine ident

Hi, we have two go-karts with 5.5 hp Honda engine & 13.0 hp Honda engines -
I'm trying to work out what size in Cubic Capacity the engines are.
anybody help?

From those power figures, I'd take a complete guess at 50cc and 125cc
respectively. But moe info on the engine types would help. like
2/4-stroke, OHV/OHC, whatever...

Of course, you could always rig up some sort of pipe arangement with a
plunger on one end and the other fastened to the plug hole to measure
the swept volume.

Google is your friend....

 

Four stroke OHV

tried google it give me every thing else but not the CC - so google isn't my
friend at all

Fluke

Has a list of models.

Google for [<model> bore stroke] produces a lot
of hits you may like.

e.g. [gx390 bore stroke]
http://www.honda-engines-eu.com/en/engines/models_range/gx_range/gx390/index.jsp

Looks like the 13hp may be 390c and the 5.5hp 160cc.

 

It looks like you are quoting gross hp. Net hp figures can be found at the
following:

http://www.honda-engines.com/engines/gx160.htm

So it looks like the 5.5hp is a 160cc and the 13 hp is the largest GX series
motor at 390cc.

And I found the above site by googling "Honda go kart 5.5 hp engine".

cheers Tom - I used google myself earlier this morning (thursday) I found
lots of useful info, but struggled to find a clear CC for these engines -
the site you posted here says ** (163 cm 9.9 cu in)

Listen guys don't get me wrong here - I did google this and found lots of
info but nothing was clear, my thoughts were if somebody worked in a hire
shop/had one of these engines they could have given me it straight - if you
don't ask you don't get in this world I'm afraid.

Measure the bore diameter of the cylinder and the stroke of the piston ftom
BDC to TDC.
Using mathematics you should be ale to find out the volume in CC.

V= [(Pi) x (D squared) / 4) ] x S

where:

Pi = 3.14156
D = bore diameter in centimeters
S = stroke length in centimeters

V = volume in cubic centimeters

Measure the bore diameter of the cylinder and the stroke of the piston from
BDC to TDC.
Using mathematics you should be able to figure out the volume in CC.

V= [(Pi) x (D squared) / 4) ] x S

where:

Pi = 3.14156
D = bore diameter in centimeters
S = stroke length in centimeters

V = volume in cubic centimeters (CC)

 

Perhaps he doesn't want to take the head off.

He could put the piston at BDC, fill the bore with oil and upend the
engine above a measuring flask for a few hours.

Or send in the pixies.

 

Easier yet: Fill the gon dab cylinder with water while piston is at bottom
dead center, then pour the water into a measuring cup.

LOL....

 

What a good idea.
