hawk dlx 250, mouse nest high throttle

[WNY hawk dlx]

Hello I just bought a hawk with efi. when i got the bike home it was running pretty smooth. I checked the airfilter box and there was a huge nest in there.... I cleaned it out and the now bike runs at very high idle. If i press the spring back on the bottom of throttle body I can get it to wind down a bit, but I dont see how to actually adjust the throttle body spring where the cable goes in... also wondering if it has to do with the comoputer, since it looks like it was running with that nest in there for awhile. any help would be appreciated!
