Looking to buy first kit
New to the forum and the whole idea of putting a motor on a bike. Lookin to buy a 66cc flying horse from bikeberry.com. Can't spend more than 200 and on the website I have the option to upgrade the carberator to "speed" or "performance" carb. Can anyone tell me the difference and if it is worth the extra money? About 20 for the speed one and 50( too much ) for the performance. Also has anyone had good experiences with bikeberry.com? Thank you in advance in case I have trouble trying to use the forum lol.
