Seller was very responsive and polite about the entire process of setting up the kit! Kit arrived with a punctured oil valve cover ,seller sent an entire replacement engine out! I'd buy again but I highly suggest you get a different throttle ,this throttle does not wind it self down when in use. You have to manually twist it to slow down. Users beware if your throttle accidentally is twisted down it stays down ,this might cause the bike to take off when starting it up. Also beware there is a rubber ring you need to place on the shutoff valve or it will leak. The instructions do not make this obvious but there is a black rubber ring that is used for it. Other then the mentioned this bad boy takes off and I got about 25 on it ,I'm sure it will go to 30 if your not as heavy as I am.
