I think I might have made a Bo Bo I bought a 20mm carb set off ebay for $129 but i only have astock motor as of now . My question is can I run this kit with stock engine or do i have to wait for the big bore kit? HELP
Any body out there with this set up?

 

You will have to go way down on the size of the main jet. Having a carb that big on a stock motor will probably take alot away from the bottom end.

 

You will have to waite to use it with a big bore. An xr70 carb that is a 16mm is as big as you can go without ruining the performance.

Hey ATOM will the 16 carb fit right on a stock fiddy or do you have to get a different intake elbow or whatever it's called???????

 

Use an ATC70 intake. It will take care or any clearance problems.
