Engine Identification

[JD/QD]

Can anyone help me identify this motor? I asked the seller for some info but he had nothing. Thanks for any help.

Its 2 stroke.... or at least it has the standard appearance of one..

there are two 125cc 2strokes on that image..
and two different ones at that..

both appear to be legit kart racing engines.. (maybe bike engines.. I doubt it though)
thus both must have an ID on the crank case, the cylinder and the clutch cover.

post pictures on all markings you can find, and we can tell you what it is

Thanks, here’s a pic of the one on the floor. No pics of anything number or model wise off the one that’s actually on the kart. I’ll see if I can get him to take some pics.

Ok, got some pics of the one that’s on the kart.

The one with four bolts on the head looks like an '89+ Suzuki RM80. The one with five head bolts appears to be a '90s Honda CR125 and is missing at least part of the power valve linkage.

Thank for the info. Would I have difficulty finding an expansion chamber/ muffler for the RM 80?

Silencer(muffler), no, but if you want an expansion chamber(pipe) that fits in a kart, then I'd say yes.

 

[JD/QD]

Yes, that’s what I was trying to ask. Kart specific. Thanks for the help.

yeah unfortunately bike engines on a kart don't make much sense most of the time

The D106 prefix on the engine code suggest a 82cc engine,
IDK about exact bore and stroke 48 x 45 or such I think..
Anywhoo.. you'd need to find a kartengine with similar specs then you might
be able to reuse the expansion chamber (just need to adapt flanges)
the comer SW80 is no match I'm afraid (50some bore 36some stroke)

I think you'll have to make your own for both in the end...
