What jet size?

Recommended Posts

I have done a few mods to my sons crf-70. I opened the air box, and took the insert out of the exhaust. After doing these and not changing any jets I notice that they do have to be changed for sure. My question is what is the stock sizes in the 70 and what should I go to? Thanks in advance

The stock main is a #62, a #65 should put you in the ball park.
