screaming eagle 103 stage 4
Just had a 103 stage 4 race kit put on my 2007 sg. I allready had a thundermax ecm on the bike. The 103 kit included the 58mm tb with high flow injectors. The bike rips unbelievable throttle response, just blipping the throttle results in a hard powerful surge of instant smooth power! Best $ 3800 I ever spent. Here is my problem the bike stumbles and pops during warm up once warm it run great althought the idle fluxuates a little. I called thundermax sent them a download of the bike and they told me that the 58mm tb was to blame for the poor cold performance stating the tb throttle plate shaft has to much play. Anyone have this set up or have a similar situation? Gregg
