I'm interested to hear how the 30 series on the 13hp held up after more use?

[@uksmalltorque5563]

Surprised me to be honest. I have changed the belt once but it’s still running fine

[@jonahbmcs7960]

I have one of the hard drives and we have it all sprayed up red and black but haven't got the new engine yet

[@uksmalltorque5563]

Do you know what engine you will go with?

[@jonahbmcs7960]

Mabye 6.5 or 13 hp

Hello I have the same kart for my kid but I'm missing Jack shaft have to make one. Could you tell me what the tooth counts are on the Jack shaft

[@uksmalltorque5563]

26t in 10t out

[@mariogiordano7285]

Thank you big help

[@jasonsullivan713]

What's the top speed?

[@uksmalltorque5563]

It should be good for at least 30 at about 5,500rpm but I will do a video when I finally get out on it. Weather depending

[@uksmalltorque5563]

Managed to do a top speed run and saw 37mph but given the inaccuracies of speed apps I would go with 35mph to be safe. I was surprised at this but happy

Did that 420 fit preexisting motor mount holes, and did you need any spacers it we're you able to mount directly to stock plate? I'm doing a similar build.

[@uksmalltorque5563]

Justin Pfizenmaier I had to raise the engine to fit the torque converter. I wouldn’t recommend fitting a clutch, so if you raise the engine by 75-100mm and fit a 30 series torque converter you will be fine. Its all very tight but manageable. Let me know if you need more help.
