jet size for a tb 88, stock carb, Help

I ordered a TB 88 for my xr70 an forgot to get the jet kit. Who has used this setup and can suggest a ballpark jet size?



If you intend to use the stock OEM Honda carb, you need to go up to a #62 main, minimum.

he has a xr70, 62 is stock.

the jets for the xr70 carb are rare but they are out there, known as "kehihn small style".

68 is good for sea level
