exactly what the man above me said. It proved to work great on a friends qt-50

Re: bigger carb on my qt50

Mikuni VM18-144. Slide a piece of PVC pipe over the intake manifold as an adapter. It's either 3/4" PVC or 1" PVC. One of those two is the exact size. Just cut it to length and you are good to go.

Re: bigger carb on my qt50

if im doing this to the carb am i going to have to do somthing with the exhust bc is bringing more stuff in at a faster rate is my exhaust going to have to handle pushing stuff out faster or is this not going to hold me back?

Re: bigger carb on my qt50

I run the Mikuni 18 as well. You get them on Ebay for cheap and they are easy to tune and real reliable. I didnt have to do any jetting, it runs good (stock QT50)

I used rubber for around the intake but am going to upgrade to the PVC...never thought of that.

Re: bigger carb on my qt50

about a 70 $ price range for that carb or should i be searching for something cheaper?

Re: bigger carb on my qt50

i would get an expansion chamber if your bike doesn't have one yet. then up jet. ian expansion chamber is the biggest gain in 2 stroke motors other than not running right to running right.
