So I was one of the first to give input to Mr. Horsepower. Here's what I said (post #8):
"I don't believe that the LS650 motor is under stroked. In fact, it has evolved from a 400cc engine where they increased stroke and bore to achieve a capacity of 650cc. There is opportunity (as proven) to increase the bore and compression ratio. The stoke is a more involved change and may not yield results that justify the efforts.
But by all means, have at it and keep us informed. Be prepared to go through several engines in the process of testing."Suzuki has a history of taking small displacement bikes and then boring and stroking them to achieve additional capacity. I've owned several. Typically when Suzuki punches out a motor, there isn't a lot to be gained in the stroke, but there usually more room left in the bore so cylinders can be rebuilt/refurbished.
At no time did I say it can't be done, just that it's probably not worth the time, money and effort. Experience has shown where the low hanging fruit is on these engines. Beyond that you're into cubic dollars. Lots of failure and retesting.
But I love testing. I work for a company that makes aerospace components and we do a lot of DO-160 / MIL-STD-810 testing here. Testing will always surprise you. You just never know how things will come apart.
