Took my buddy to pick up his 2007 GSXR1000 from the dealer today. Went in for a recall and to add that new Bazazz programmer, only mod to the bike is a racefit exhaust. 10 miles down the road headed home he rolls into it in 3rd and it goes boom at 9000rpm, smoke pouring out the exhaust and starts knocking and goes dead on the side of the road, hit the starter a few times and it just pours raw gas out the exhaust!! When the shop came and picked it up on the side of the road they said it ran fine on the dyno and made 175 and said the air to fuel ratio was correct. What do you guys think may have gone wrong?
