.020 over bore piston, will it fit?

[wolfgang123]

So i am need of an upgrade and i saw on ebay a .020 overbore flat top piston and rings set for $25.00. Would i be able to fit this bad boy in with cylinder without having to bore it?

Also can i use a gx140 flywheel on my gx200 clone?

------------------------------

EDIT: i just double checked and its a dished piston not a flat top so what would you guys do...flat top piston or over bore??

flat top all the way. You would gain hardly any thing from going .020 over.

Ok thanks. What about the flywheel?

If I understand your question correctly, a .020" overbore piston, would require you to bore the cylinder over, to fit the piston. Scott.

they make a gx140? a gx160 will fit a gx200 though

gx140 is the 5hp (production 1984-1993). From the part numbers that I have found it does in fact show that the gx 140 and gx 160 share the same flywheel. So it should be 4 deg advanced when you install this flywheel.

perfect answer thank you.

I was reading on 4cycle a while back that the GX140 flywheel has a smaller taper than the GX200. I have a 140 flywheel so I could compare dimensions if anyone has them for the 200 FW.

To answer the other question, an 0.020" oversize piston definitely will not fit in a stock cylinder without boring it to fit.
