Pulled my carb apart yesterday and found 155/62 setup for jets (I believe it was 62, maybe 65). Bike seems to run and start well. I have ridden the wheels off of it in the 1.5 years I have had it. Mods: 1. Snorkle removed 2. UNI 3. Header welds ground down some 4. WB Hot Tip (stock pipe) in place of stock baffle Questions: 1. Is there anything to be gained by going richer/leaner on the main or pilot? 2. Should I leave a good thing alone? 3. What is stock jetting? I usually ride between 500-2500 ft., but plan on riding towards 8,000 feet soon. Should I lean it out for this ride?
