hey, im either getting a YFZ or a Z. Im looking to put a lot of money and time to either bikes. Im going to race mx at my local track every time there is an event which is about 2 races a month and i will go there pretty much every saturday to practice. I also will during the weekdays be trail riding and be riding wfor fun nothing competetion. Im not looking to maintain the bike like a 2 stroke ( iv had a banshee and hated it because it was a money pit just to fix thingS) basically I dont want to use the money on the quad to fix things I want to use money on the quad for aftermarket parts. Please im having a rough descition. I want the YFZ more but im afraid the maintenence will be like a banshee. iv never had more problems with a banshee then any other ATV iv ever seen road and owned
