I've read and read, Yet I have not really found a clear answer.

The Topic is.... BIG BORE KITS.

Can a few of the experts please give me a clear answer, no matter what it is.

1. Is there a significant power difference?

2. Is there a reliable big bore kit?

3. Is there any combination with big bore kit with exhaust that has been successful.

Thanks in Advance! Craig in Wyoming

1) definitely. no replacement for displacement.
2) the one a member here makes
Kick Ass 61mm / 170cc Piston, Prototype - Page 3
3) i haven't tried, so no useful info here

Thank you for your thoughts! I'm sure there are so many like me , with that wondering question. there are times when it would be nice to be able to go traffic speed (65) with out running with RPM's at a Max!

Just (mostly :)) guessing here (only ever bought Malossi and/or Polini scooter kits; 50cc && 150cc base; 2-stroke & 4-stroke, respectively), but:
2. Is there a reliable big bore kit?
Most certainly, reliable is highly-subjective in the case of cylinders. 99% you are shortening the lifespan of the engine, when messing w/the bore (even when replacing w/the entire liner, where possible). This is something that I would personally never do, if I had plans to ride w/that engine for a long time (a large number of years and/or as my daily driver).

Much better to stick a turbo on, no?!?? (and/or a lil' bottle of NOS, hehe)

Whatta ya think??

P.S.
no replacement for displacement.
Love it!! =)

^^ So true, ofc.
