The following information was received in 2008, a Tech Tip sent out to its dealers by Yamaha.
SYMPTOM:
"On some 2007 SVS1300 models, a rattle noise may be heard when the transmission is in neutral and clutch lever is released. The noise stops when the clutch lever is pulled in or the transmission is not in neutral."
CAUSE:
"The primary driven gear on the back of the clutch basket is dampened to reduce drive/driven gear lash noise. In some cases the dampening may not reduce the gear lash noise sufficiently for customers' expectations. This gear lash noise sounds like a rattle near the clutch area of the engine. While not a defect, the noise can sometimes be reduced to a customer's satisfaction."
REMEDY:
The primary driven gear dampener was changed on the 2008 models from a rubber cusion type to a spring type to reduce rattle noise. In addition the 2008 model primary gear has slightly more gear lash to reduce whine noise."
The 2007 primary driven gear will be superceded to a kit containing the 2008 parts in the table below."
(added: The box that came from the provider of this information has a complete clutch assembly, except for the two gaskets for the side case and clutch cover, so make sure you dealer has them or orders them.)
The part number is 99999-03812-00 Driven Gear Asst Set
This should be covered under your warranty and cost you nothing. The dealer may charge you for oil and the two gaskets that are not in the clutch kit, but this individual's dealer also provided this at their cost.
