Which jets for crf-70? by DocCRF-X250 » Fri Mar 13, 2009 5:22 pm
I have opened the air box and drilled out the baffle in my sons 70. After a short ride I realized that I will need to rejet. What are the stock jet sizes? Also what should I go to.

'07 CRF 70 (sons)--Pod air filter, opened exhaust and re-jetted
