arit Posted April 12, 2020 Share Posted April 12, 2020 (edited) I have just stripped cleaned inspected carbs. The bike is bone stock (airfilter exhaust carb settings etc) but it was running super lean, hesitated around 7000roms before clearing and had to run pilot screws at 4 turns out for it to run ok down low - was popping etc... Thought it might have been crud in carbs so cleaned them all out. Wasn't too bad but won't know until back on the bike. Everything is standard jet sizes 97.5 and needles @ position 3 as per factory setting. My question is would it be smart to raise the needles one notch? also anything else I should be checking that would cause a lean condition? cheers ari Edited April 12, 2020 by arit Quote Link to comment
dago Posted April 12, 2020 Share Posted April 12, 2020 Check for air leaks on the rubbers Quote Link to comment
arit Posted April 12, 2020 Author Share Posted April 12, 2020 will do, whatever is causing the lean condition its across all cylinders. All the plugs are light grey Quote Link to comment
CockneyRick Posted April 13, 2020 Share Posted April 13, 2020 115 mains, middle clip, 47.5 pilots & 2.5 turns out. Not tried em yet though Quote Link to comment
p4ddy Posted April 14, 2020 Share Posted April 14, 2020 (edited) Double check your air filter is seated correctly. I've had the nut work loose before and it left a gap. Just seen your other thread stating the pilots were out 4 turns from the previous owner so maybe not a loose filter then? Edited April 14, 2020 by p4ddy Quote Link to comment
