[QUOTE="JC Soto, post: 453686, member: 35291"] Katoum, Sorry about the typo. The stock needle is OBDVT. The aftermarket needles I tried were OBDVP and OCEMN. Both after market needles are a bit richer. The DVT is slightly narrower in main diameter, and the EMN had more taper (among other properties - I am using James Dean Jetting Guide spread sheet). I got some backfiring with the DVT when stopping with the engine or hesitant under 1/8 throttle; needle on #4, 170MJ, 55PJ. The EMN felt about right on #2, 165MJ, 55PJ. Also note that I live at 8400' and ride from 6500' up to 11700' (Colorado, US). Like I said in my previous posts, I set my FS at 1 3/4 to 2 turns with the 55PJ after my third or fourth carb rebuild/cleanning! It did get better after fully disassembling the midsection of the carb. Hope this helps. JC [/QUOTE]
