Chris-in-Cali Posted March 8, 2009 Report Posted March 8, 2009 I had issues with my mains in my 34's. The MAGIC number for me was 172 and CEL needles work wonders on 34 pj's Quote
speed-racer Posted March 8, 2009 Report Posted March 8, 2009 Start with 165 and work your way down. Look at your plug, it will tell you everything you need to know. Quote
bry Posted March 8, 2009 Author Report Posted March 8, 2009 Start with 165 and work your way down. Look at your plug, it will tell you everything you need to know.i cant get a good plug reading because i cannot use the throttle like i should if i get the bike under a pull it cuts out but it revs great sitting still..

speed-racer Posted March 9, 2009 Report Posted March 9, 2009 Did you put new plugs in it when you dropped from that huge main jet? Quote
