Honda and Clone Engines / Re: Upgrade kir for GX390 on eBay
« on: July 30, 2018, 10:20:27 am »
Okay, I did my research and found out that the GX390 crankshaft is 3/16" longer than the GXV390 crankshaft.  Not enough to make a difference.

The Honda Harmony riding lawnmower came with a GXV390, rear engine drive.

Yes, your engine is running backwards when you shut it off.  It is not diodes from your charging system, that is a completely different subject.  I think you have your timing off on your engine.

Forgot to mention that I will bore the GXV block for the 90mm piston.  The stroker crank is my important question.

I would take the carb off and make sure the mounting gasket didn't slip to one side.  When you have the carb off, study the adjustment screws.  The idle screw should be screwed in till it bottoms out then opened 1 1/2 turns, then fine tuned when the engine idles

I recently lost oil pressure on my 2001 GXV390 and seized the piston.  I was looking at eBay and they are selling a 16hp upgrade kit for the GX390 that includes the 90mm piston and (I believe) the 66mm stroker crank.  I have figured out the piston and rod will work after grinding off the splash tang, but my question is can the stroker crank work in my GXV engine?  Or are they not able to accept the extra gear and bearing the GXV needs?  Are the GX cranks shorter or something that keeps them from being used in a GXV390 engine?
