Wiseco 440,,,,??
I wouldnt say boreing it out takes away from realiabilty of the bike....but i do believe that it wont last as long as if you kept it stock...
really any time you start taking apart the engine to do mods your gunna take a LIL chunk of life of the bike with it
many will argue this, sure your bike might run with no problems for the first 5 years or so, but i bet you'll have problems in the long run ( most ppl dont keep a bike that long so they dont have to worry about it)

As to reliability of boring. Boring the stock sleeve too large will ultimately lead to wear and or sleeve damage. The stock cylinder has an aluminum sleeve at 90mm (stock) boring that to say, 94.5mm, means you are thinning out that sleeve to the point where it could.. one, get very hot as the metal is thinner, 2, bend or break, causing uneven wear or a catastrophic failure. That is why companies either 1, offer a complete new cylinder with a larger bore and thicker sleeve, or 2, offer a steel sleeve insert that can be put into the stock cylinder after the stock sleeve is removed.
Also, you are correct in saying that anytime you modify the original intended design of an engine, you are submitting it to a standard that it was not made for.

just doing the 440 piston is a step in the right direction, but with out the things that go with it
is near to being a wast of time . you really as well will have to go with a full pipe, a slip on just don't get it, open up the air box ,re jet, since you have to take the head off any way port & polish is smart but not absolutely necessary in most cases it will give you a bout 3 hp . cams are diffidently going to help but can be put in later with out to much difficulty. and oh yes a timing chain . all this should get you to 45+ hp at the rear wheel but no promises.
pretty good when you consider the stock unit comes in with about 27hp at the rear wheel.
