Everything worked as expected! Clocked the scooter in at 20mph today! Very happy with how fun and easy this scooter is to rebuild. I can tell you rebuilding this engine twice now that this kit does the trick and everything fits nicely.I must’ve had a hairline fracture that got worse over the first few heat cycles and had developed nasty exhaust leak within the first three days of my rebuild. I contacted WhatApart and got a whole new kit no hassle, really appreciated how easy everything thing was. Ill definitely be looking for the name next time i need scooter parts lol.
