SLORYDER Posted March 23, 2009 Report Posted March 23, 2009 (edited) I am right at sea level in south Louisiana and it is humid as hell (not sure if that makes a difference). I asked the guy at Trinity and he said 155, without even asking me my elevation Edited March 23, 2009 by SLORYDER Quote
wesw Posted March 23, 2009 Report Posted March 23, 2009 i know they are different than cubs but somewhat the same try 48-52 pilot dgh mid clip and 160 main and go from there would be a good start. to make sure the pilot it should idle for like 4 mins if i idles then dies its cause its rich. Quote
SLORYDER Posted March 24, 2009 Author Report Posted March 24, 2009 Wow I just checked the mains and whoever sold me the carbs were running 185's Quote
dajogejr Posted March 24, 2009 Report Posted March 24, 2009 Well...you were by no means "lean..." LOL. Who knows what the carbs were on before, but I can tell you sometimes when a turn key engine gets sold carbs are left VERY Fat and final tuning is on the owner... I agree with Wes on the pilots. I think a 155 to 160 main will get you right. I tend to like the CEL or DEK needles for gas on PWKs. Quote
rubberneck Posted March 25, 2009 Report Posted March 25, 2009 Wow I just checked the mains and whoever sold me the carbs were running 185's I dont know why it is, but some of us have to run big mains on our 39s others dont. Maybe its the needles. I have DGH needles on a 4mil cub, and 185 mains were ok at 90 degrees, went for a night ride at 60 and lost a piston too lean. Live and learn. My bike wouldnt make it out of camp with 160s. Motor was Pressure tested when built and after lost piston, tight as a frogs ass. Some bikes just need big mains. Quote
