I just need an opinion here.. Just got the valves done by the Honda shop. I ride the bike home (8miles) everything is great. Ride to work the next morning (24miles) great. Riding home just get on the highway going about 75 I hear a click noise and the bike shuts down and the FI light comes on.. Get the bike towed to the shop (5days later) The shop tells me that a cam broke. The guys asks me if I down shifted on the highway. he said the high revs broke the cam. I was in 6th gear when the bike shut down. Can anyone tell me if their is a possibility that when they did the valves they screwed up. When I told this to the service person he said the bike would have never been able to start if it was something they did. This could be just bad timing but of course if they did something wrong they would never admit it..Thanks for any help.. Also the fi code was 18 (cam sensor) I'm wondering if its just the sensor and they are trying to pull a fast one.
