Picked up two '04 RM65's for my boys. Cleaned the carbs on both of them, the stock one with 190 main/25 pilot jets runs great. The other has a DEP pipe, 180 main/22.5 pilot and it sputters pretty much through the entire RPM range. Starts and idles great. What would you guys suggest for jetting with this pipe? I may switch the carb tonight and see if it helps. Thanks for any advice.
