I have a great bike but would like to get some more power out of it.
I have a Arnada with the following mods
-72cc contessa bore
-7.9 to 1 gears
-24 carb
-ct crome mani
-typhoon pipe
-oil plug (pre mix at 32 to 1)
Here is the question. Would changing the bore from a contessa to a corsa make a difference?
I use the bike as my daily ride and planing to build a spare motor. I can just save the contessa for the spare.
Thanks in advance for any help.

well just buy pg long pipe,28mm carb and corsa bore. Yes it will make big difference!
typhoon pipe got good low and mid range, not top speed.

I ride to work every day to town so I am tring to keep the noise down. (running a air box) I was thinking of the bigger carb and bore, but kinda worried about a louder pipe. Would the pipe make a big difference?
Thanks again

noise come from a big carb 28mm and make pipe very loud.
pg long is much better than typhoon pipe.
I ride everyday my mod elite w/ pg pipe. cops doesnt bother me at all or mess around.
if you dont like noisy pipe, just run your typhoon pipe.
no matter, when ever any mod parts changes , still need to tunes/carb,rollers and jets. all the times!

Greetings:
My LeoVinci pipe is tuned for midrange and is eerily quiet. In fact when I switched from the stock airbox to an open K&N filter, the noise from the left side became considerably more intense than that from the exhaust. I kind of like it, because I can control it with the throttle, but my neighbors may or may not agree.

Right now I am able to get to 60mph. (on a flat) it take a while though.
I was thinking of another pipe but worried of the noise.

the contessa piston skirts are longer than the corsa so you can cut them, run 7: 1 gears, do a japan dio trans convertion= cheap speed

Here is the update. Wife just bought me a corsa kit. Going to save the contessa for a spare. Still braking in the motor but aready feel a differance. The sound is deeper and revs up faster. Can't wait till I can top it out. Now I need to beg the wife for the pg pipe.
