I posted the following in the vtwin forum and have not gotten a response so started looking at some of the threads and the site seems to have little activity. Is there someplace else to go thanks Have a 09 Heritage with a Jims 131 Screaming Eagle 103 heads, 58 mm throttle body and 4.9 grams per second injectors (part number 27797-07) I purchased the bike used and called Jims with the serial number on the engine cases and above info is via them. I forgot the cam info and compression ratio. When starting cold it is necessary to crack the throttle a bit for it to start. I have been reducing the duration the injectors are open but seem to be getting no where. The current setup calls for 59.9 ms at O degrees Centigrade, 39.9 at 20 degrees, 32ms at 32 degrees, 25ms at 48 degrees, and 20ms at 64 degrees Centigrade. From there on it is 17.9 ms. These numbers are for the super tuner and are much lower than when I started. I have been dropping the ms in .3 intervals and wonder if I need to just drop several numbers. BTW it does seem to start without touching the throttle when it is warm. That is new so I am on the right track but tired of taking off seat and dropping it in small increments. So hoping someone has some good input. Thanks for any help. Do not forget Mother's Day is May 8. Best to all.
