Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I have heard the rear camshaft on the twin cam engine is weak. And that too much power will cause it to break,causing the engine to stop running. Possibly placuing the operator in a traffic safety situation. Upon contacting, I was told this was a problem, but they were not going to recall it. I also noticed for the year 2000 models they have changed the cams and they are now splnined. I feel this is a safety concern for motorcyclist and should be addressed before some one is injured.”
