christoph.tamz Posted May 28, 2018 Report Posted May 28, 2018 So I had a shop give me keihin jets. 170 main, 55 pilot. Needle on second clip. 500 above sea level. 421 assassin, 38mm pwk carbs, cool head, cpi in frame, shearers. Anyways, I went riding and was lean as hell. Moved the needle to 4th clip and it helped but not much. My kx125 beat me in a race. Wtf? Sent from my SM-N920V using Tapatalk Quote

Also what needle What is your compression/ fuel your running as well. Ported motor? Edited May 29, 2018 by Ayesully810 Quote

Ayesully810 Posted May 30, 2018 Report Posted May 30, 2018 Did you plug chop the main yet? How does it start and idle with that pilot. You should see what needle is in there. What shop provided you with jetting specs? Quote
christoph.tamz Posted May 30, 2018 Author Report Posted May 30, 2018 I did not plug chop yet. It starts first kick. And a local company, c&m Powersports. He just googled cause he didn't know Did you plug chop the main yet? How does it start and idle with that pilot. You should see what needle is in there.

Ayesully810 Posted May 30, 2018 Report Posted May 30, 2018 (edited) If it were me id see what needle is in there first and then chop the main CGl or CEL for your setup is usually what people run for pwks. Edited May 30, 2018 by Ayesully810 Quote
kawa110 Posted May 30, 2018 Report Posted May 30, 2018 140 psi on the cylinders....Did you pressurize the crankcase with 6psi for at least 6 mins? Quote

kawa110 Posted May 30, 2018 Report Posted May 30, 2018 Sully post a link to your shirtless video...Christoph, you replyed “yes” to pressure test, did the crankcase hold 6 pounds air pressure for at least 6mins? Quote
