I've come a long way in upgrading my scooter (http://www.scootdawg.net/showthread.php?t=53309) and I feel it's time to get a BBK (http://www.scootdawg.net/showthread.php?t=53311)

Only problem is... I'm not sure whether to get the long lasting 72cc kit with performance camshaft to settle for speeds of possibly 45mph, or to get one of the 80cc+ kits and sacrifice some engine life for power.

How long will my engine last if I'm riding it every single day with a 49cc vs. 63cc vs. 72cc vs 85cc vs. etc.?

I'm thinking of getting this one:
www.amazon.com/Scooter-Bore-72cc-QMB139-Stroke/dp/B0043X28S2/ref=sr_1_6?ie=UTF8&qid=1369438091&sr=8-6&keywords=47mm%20big%20bore%20kit&tag=vglnk-c198-20

But, again, I'm pretty damn unsure.

Maybe I should get this one...

If you get the 80cc kit you'll always wonder about the bigger kit. I say go big

Hi
If you don't abuse the power and keep the rpms to a reasonable upper limit quite a long time
I've got close to a year and over 4,000 miles on my 4t 95cc BBK scoot with no major issues
I did go with quality components such as NYC and DR PULLEY
Take care and ride safely dear friend
Yours Hank

Thanks Millsc, that is kinda true... I originally thought that 63cc was enough because it's just a little more than stock, but now I'm struggling with 40mph and figuring out roads I can take where I won't get squashed. a good and big bbk would finally mean the end to cars passing and honking at me...

Will running the stock carb restrict the power of the scoot? And if it restricts power does that mean it will last longer? Are there ways to extend the life of it all or keep it just under its pinnacle power to lessen the stress on the parts?

I think I have just enough technical know-how to install a bbk, but fixing anything that goes wrong afterwards is another story...

That sounds great compared to the stories I've read posted by miscelanious users on other forums saying they only got theirs to last 2k miles before something snapped. How much more life do you expect out of the scoot?
