[@mhz-yn9gh]

Sounds incredible, Mr Xiaoxu!! Wow 🤩 🎶

[@jeremiah1412]

Sounds a little like a 90’s CBR900RR

[@benjaminkreimel8651]

Sounds better than toyan v8 crap

[@jiangxiaoxu8035]

Agree. 😂

[@YouTubeSupportTeams]

best sounding model engine ever

[@memeAlexcheramie]

Amazing how you can make an engine sound more aggressive just by putting larger exhaust tips

[@maniiez]

Just ask any Honda boy 😂

[@thqp]

Absolutely lovely!

[@CISON-ENGINE]

NICE

[@raulromero2105]

Buenísimo!!

[@richardreynolds8052]

Can you show the underside of the base for an amateur like me?

[@jiangxiaoxu8035]

The underside of the base is also a flat surface, the base is actually an aluminum case, all the wires are hidden in that case, also with some rubber cube inside to reduce the resonance.

[@richardreynolds8052]

What carburetor did you use? Thank you.

[@jiangxiaoxu8035]

That's VX 18 carburetor

[@RollingFish91154]

it's an OHV

[@Jesse8478]

advertises new exhaust doesn't show exhaust side....

[@masatau5576]

[@FXCBOY]

[@dblnaknak]

Where did you find the fan?

[@jiangxiaoxu8035]

The fan is 3D printed.
