C21,c28 and C29 on my K6 GSXR600
Just picked up a 06 gsxr600 with 10k on it. Looks really good but it has c21,28 and 29 codes going right now that i personally verified. Prev owner said it only needed the stva replaced. I havent dug in yet but i believe the butterflies and set all the way open at the moment. It idles at 2000rpm all the time. Runs 200-220 in 95 degree weather we are currently having. Just want to know where i should start or what i can test so im not replacing stuff i dont need to.
