Hey board, first post on here, the info has been great! I bought my son an '01 ttr-125 that has a fmf pipe on it. I read the thread on jet mod's and had a question. I looked and the jets in it now are 105/15. With the FMF pipe should I stick with the 110/17.5 combo or do I need to go bigger because of the pipe? FMF's site say's stock, which seems strange! Thanks in advance!
