.. cylinder upgrade assy instructions ..

[wordslinger]

...sweet..when it comes to all this cylinder upgrading, imma learning...

[Shaka]

Sid- I believe in the manual it is referring to the opening into the crankcase.  The cylinder bore size is 39 mm.  Seems a bit small, but Idk.  I just measure the OD of my stock cylinder skirt and it is 54 mm so I know my crankcase opening is about 55-56 mm.

[wordslinger]

...i think 39 might be about right for 49.5 cc...

..there's a formula....what is it..dammit..

[sidthesloth]

Sorry, my mistake.

[wordslinger]

..no worries, mate...


..i have always wanted to say that...lol...

[Shaka]

Cylinder Volume = Pi R²   

[wordslinger]

Cylinder Volume = Pi R2 

...pies was made to be eat'n....


..and they're round, not square...

[shubonker]

So i guess its between the 70cc or 80cc, i'm leaning towards 80cc myself.  Dont know about you slinger. 

[wordslinger]

...yeaaaahhhh..i don't ...need a lot of ...speed....damn near ok with that....dang...


..i need a another year or so, along with the speed increase...

[shubonker]

Come again?

[wordslinger]

..i can already hit top speeds of some 72 cc kits..


...there, i said it...

..what i DO need is the ability (guilty) to haul my ass up these damned hills at 45-50 mph...gps...

[sidthesloth]

We have both kinds, round aand square , and yep, theyre both made fer eatin. Think 50 cruise. Hey, the other scoots will be drafting you. :-)

[wordslinger]

.....yup, that's what i'm screamin'.......lmao...they do already....

[shubonker]

If you're already doing what others are doing with 72cc kits, than just imagine how much more power you'll get when you do get a 70cc kit.   

Cars on the road will be at your mercy!

Almost.

I don't think a kit it's made for speed , i'ts made for power ,which you could to transform in speed with other upgrades (smaler ratio on gear, that NCY transmition kit if it have bigger surface on variator and driver pulley and with a bigger belt of corse it will give you more speed ...etc )
