Tried and true 72cc BBK?

[phatboy]

Hey,

Bought a 2006 Agility 50 with 300 miles. I cut the CDI myself but I think it has a jet and variator boss upgrade, it goes 43 on flats (and i'm 280 lbs.)

what i don't like is that uphills aren't great. there's this long, 1 mile long steep uphill leaving my house, no way around it. Its a 25 MPH street but people like to go 30+, and the scoot chugs along at 20, car drivers get pissed and some pass dangerously. I don't need a big boost, if I could get 30 up this hill, the scoot would be perfect, not to mention safer.

I don't want to mess with lots of things that "might" work. I have no dreams of getting the scoot perfect all around with just weights and torque springs, and I read these can hurt top speed and I like the 43 MPH which is perfect for the 40 MPH road I will ride on, if springs/weights drop top speed to 40 or below then I wont feel safe on this road.

I've done lots of reading and I think a 72cc bbk is the answer. but with so many options I want a kit that is known to work, something others have tried.

i read that some kits use the stock head and increase compression, I want a stock compression ratio, I want to use pump gas and not worry about detonation. Regular here is 87 octane and premium is 91, anything more is really hard to find.

Now don't laugh at this next part but I don't want to be tuning this thing for life, just want a bolt on kit known to work, not piece things together and endlessly tweak stuff all summer long, but just a kit that comes with all parts I need and work pretty well out of the box. Want to use stock airbox, stock exhaust, stock carb, and CDI. I don't ride this a lot and its just a weekend toy, doesn't have to be the best stuff, I doubt I'll ride this more than a few hundred miles a year.

There are endless options some with and without heads, some with jets, some with cams, some with weights, on and on. THe simpler the better, i think. I want to buy from a reputable shop even if it costs a bit more (not ebay.) Im in the USA so would rather deal with USA supplier.

This is one I found

There's many more from searches but for some reason I keep coming back to the above kit. Anyone tried it or recommend something better?

Guess there's nothing tried and true

So how about instead you guys tell me what kits and what jetting worked for you. Did you use the stock head, what jetting etc.

ideally looking for replies from those using stock carb, airbox and exhaust and I don't plan to change those.

Go back to the enviromoto page. Get an ncy 72cc cylinder kit and ncy cam. That's the kit I run and its holding up great for me

Its hard to really say what kit is tried and true because tuning is everything with any kit. Its the unfortunate truth. In my experience the 72cc kits arent that much stronger than stock and I would recommend the 50mm/82cc kit. Once you change any power output you have to retune the transmission. If I were you I would find a reputable scooter mech and let him take reigns over the tuning if you dont want to.
