“Charging LED showed that the bike was not charging. Stator and voltage rectifier/regulator failed. The charging system was no longer charging the battery or supplying electricity to the electrical system. Replaced stator and voltage rectifier/regulator. Old stator is still available, threw out the r/r. Replaced the oem stator with an after marked switching stator.”

“The motorcycle start-up is not consistent. More often than not the main high beam light would dim indicating that there is battery, but it does not start, and when this happens you cannot even hear anything clicking. Start-up on the first try is less than 1% of the times. Internet research yields results of this issue being common among motorcycles of this year and model yet there is no documented recall from the Suzuki. According to user's manual everything on this bike is properly connected and functioning as it is the case for most reported issues. …”

“I have a Suzuki motorcycle it's 2005 c-50 boulevard not a c-90 as that is the only selection in the next menu. The speedometer is off by 6-8 miles an hour in the plus side so when I think I'm doing 60 I'm doing 53-54. I have checked the speed with another vehicle and a GPS. I have been told it is an uncorrectable problem by the Suzuki corp. They claim all their bikes are off 8-10% intentionally from the factory. …”

“The contact owns a 2005 Suzuki C90. The contact stated that the motorcycle hesitated and failed to shift gears at low and high speeds. The gear shift fractured due to the failure and the contact had to replace the part. In addition, the battery was replaced four times and taken to the dealer three times. The failure was unable to replicate and diagnose the failure. The motorcycle was also taken to an independent mechanic three times. The motorcycle stalled several times without warning. The manufacturer was notified of the failures. The failure mileage was unknown.”
