My Zuma Build, Here is what I have... what next?

[kinggorilla]

Hi Guys... first, thank you in advance for you help and input.

So I recently bought a 2005 Zuma (2s 50cc) with only 2k miles on it, it will totally be a zip around town ride, not my primary vehicle.

I have already purchased the following:
[INSTALLED]
Malossi Variator
Stage6 Torque Control MKII clutch

Malossi Wing Bell
Yasuni R exhaust

[PURCHASED BUT NOT INSTALLED]
70cc Stage 6 MKII kit (Not installed yet)
Dellorto RACING Black Edition 21mm
Carb cable

I am contemplating what crankshaft to get to match the cylinder kit and I am thinking staying Stage6 and going with the HPC Crankshaft (I assume they pair well together)
What are your guys thoughts/experience on that crankshaft? Should I consider another, if so why?

Besides the Crankshaft, what would you all suggest next?
Reeds?
Intake?
Am I missing anything?

temp gauge, jet kits (pilot and main), tachometer and a set of tuning roller weights.

Everything Repherence says and I would get  some gears Athena makes some 14/42 gears that would put you at a great Final Ratio that you would still get good take off and your Top end would push over 60 mph with the other parts you have .

Which stage 6 out do you have? There is a Stage6 Sport Pro MKII Cylinder Kit, and a Stage6 70cc Racing Cylinder MKII. They are quite different.
I had that crank in my old aerox, never had a problem with the stage 6 racing kit fitted.

Should be a fun set-up.

I got the Stage6 Sport Pro MKII, I thought the Race kit might be more of a race only kinda situation and maybe to temperamental.

agree Wirth what rephrence said,
but if money is the issue grab a cheap tachometer for 20 on ebay and you could start tuning cvt with out any more$ just by modifying the rollers you already have, 90gt did a video on that , you can remove inner metal part and save some off, or add foil to increase weight, wait...
you would also n3ed to spend 20 on a digital scale, I forgot nit everyone already has those...
glad to hear it all went together well!
with the m2 sport you should be okay with stock crank👍

I do, I got the Polini Tach and 2 temps gauge. Reads to like 400°+ so it’ll work well.
