Awesome big bore kit! My drz was stock with a fmf, also from it sitting for awhile my stock carb was destroyed from the gas and needed a new one sooner than later. I wanted to get a big bore so this including a carb was icing on the cake, carb is really nice and takes away the stock choke line and is on the actual carb. Also has an adjustable needle, unlike stock. The 26mm carb works awesome with the 143 kit. First time I ever rebuilt a motor by myself and it started first kick when I was done, like the description says, if you know how to change a piston you can do this, if you never done it, download the 110 manual and watch a few youtube videos. Highly recommend this over any other big bore kit out there for the price. Bike sounds awesome and has much more power, also the external air filter with a shiny carb and intake manifold is a great touch.
