Just got it firing!
In regards to my stelvio ntx 1200 with 20000km I put a beetle map to it wonderful sooooo smooth huge improvement I was getting about 7.3L/100 after the beetle map it went down to 6.8/100. Mark from beetle said it should be better he recommended I adjust the valves .1 and .15 synch the bodies and reset the tps. I messed it up! I was not aware of the air bleeds so I cranked the adjustment screw ...the misfire came after this... kept seeing my manometer liquid get sucked away ... so I bought vacuum guages. I put in 2 new sparkplug new ngk caps switched left and right coils to no avail. I don't have intake leaks yet the left idling stutters sometimes 3 "pungs" in a row. 100% I know the bodies are synced at 4000rpm the idle is synced the tps is 4.8 ( and no I did not touch the sacred screw its butted against the linkage nor did I remove a ball joint. The bike runs awesome even at 1500rpm and strong but only at idle it " goes " thung thung" sometimes compression is 150 each I've checked and rechecked many times over and over. The CO trim is set to zero moving ot negative makes it worse when I go + 20 the misfire goes away. But I'm not riding it Like that because I'm pretty sure my milleage would be compromised. Please anyone?
