Vincip92 Posted April 25, 2018 Report Posted April 25, 2018 I bought a set of pwk28’s to go on a stock motor with a k&n air filter and v4 reeds. Before I changed the carbs the bike ran fine no issues with the new carbs I can get it to idle but it bogs up top and when I get it to run up to. Has anyone else had this problem Quote

Go to a 152 main, 48 pilot, JJH in the middle, 1.5 turns on the air screw and start tuning from there.. jmo Edited April 26, 2018 by JUSTWANNARACE Quote
sleeper06 Posted May 4, 2018 Report Posted May 4, 2018 Run a n68a needle in the middle to start. Check the carb boots really good for cracks n leaks. I would start with 45 pilot 145 main . Report back Quote
sleeper06 Posted May 4, 2018 Report Posted May 4, 2018 Wouldn’t hurt to start bigger like JWR said. I’ve found the jjh needle works well on ported bikes and the n68a needle on stockish engines, the are the same taper and diameter but the length is different giving you the ability to reduce fuel at important transitions off the pilot circuit Quote
Vincip92 Posted May 7, 2018 Author Report Posted May 7, 2018 No air leaks changed the jets still the same issue changed to the n68a runs amazing can’t believe how much of a difference that made thanks for the help Sent from my iPhone using Tapatalk Quote
