We need a start up and a speed run 😉😂

[@ka0bit0]

Hoping to get some video of that before the year is up lol

[@robertmason8341]

Have you dynoed it? If not, what do you estimate it’s making now? I’m about to order the same head but haven’t decided what size jug I’m gonna go with. Is that the 5ml motor? Does everything for them fit the water cooled on 16 and up engines, as in is the cylinder stud pattern the same and cam chain location. I like Frankenstein int stuff together and making it work myself. Got small machine shop so that helps too

[@ka0bit0]

Hey! I haven’t dyno’d it yet. It’s honestly been running pretty amazing with the stand-alone ecu I’m running (aracer mini x) The parts on my motor (1st gen) are NOT compatible with the 2nd gen Zuma. You may be able to machine it yourself, but the trial and errors might not be worth it lol. I believe some race shops in Taiwan sell big bore kits for your bike as well as RC Scooters here in the US.

Hey its scooternerds stretch kit, got the same one for my zuma

[@ka0bit0]

Yep! From good ol’ Mike from the Zuma forums. It’s honestly the best stretch kit for the z125. It sucks he stopped making them a while ago

[@Vonjonster]

That’s so cool. Bro Where did you get the TE37s so cool

[@ka0bit0]

Thank you! I bought the wheel in Japan.

Wow nice work!! Where did you buy the center shock kit? I want buy one~!!

[@ka0bit0]

Thanks! I bought the center shock arm from FLP a few Tess ago. Unfortunately they stopped making it some time ago.

[@vladgas5233]

This zuma is so fking sick , i wonder where did you get the engine stretched parts?

[@ka0bit0]

Thanks! The stretch kit I have is actually no longer made.

[@detroitpyro2859]

What is that bar in the middle? I like that fan cover, I ordered one but its flat doesnt have a scoop on it will that hurt the bike if its flatter to the frame and no scoop?

[@ka0bit0]

It stiffens up the frame neck to eliminate flexing. Front tire pivot point is corrected, which makes the steering lighter and more responsive. Also reduces steering shakes over rough surface.

Hey man i have question does 175cc works with an oem starter or have to be bigger starter?

[@ka0bit0]

It should, but I’d recommend getting a Koso starter just to be safe.

[@agatai2291]

This is cool, What is the size of TE37 disk?

[@ka0bit0]

Thank you! The size of the wheel? It’s a 13x5.5

[@agatai2291]
