GX 160 Bigger Bore

[brendleboxer]

I am looking to bore out that GX 160 Honda motor that I posted the crank question on a few days back. I am looking to bore it .75 mm over. My question. Is it worth the time and expense to do it? Will it make a noticeable change? Or is it a waste of time? I am going to use it for a go-Kart motor. Any suggestions or advice will be a great help. Thanks for your time.

I don't believe you will see that much difference for the money output, But if you must I would only go 0.50 over so you will have at least one more oversize to go before throwing the block away.
