Hi I have an xvz 1300 , hasa hi pitch noise comming from g/ box at high speed Thank you greg
Unfortunately, you can get noise from the transmission, clutch basket,
drive shaft, pinion gears or rear wheel on the Royal Star. No way to
tell which you have so:
Barring a failure of the clutch,
a change to a multi-grade synthetic oil THAT DOES NOT HAVE AN
ENERGY-CONSERVING SEAL ON THE BOTTLE will quiet (but not necessarily eliminate) gear and clutch noise.
Energy-conserving oils tend to make a wet clutch slip. Try Shell
Rotella-T (T6) synthetic, available at Walmart for about $19.00 a
gallon. Broken clutch springs and bent or warped clutch and friction plates can also be noisy, but that is typically experienced across the whole speed range; fixing a problem like that would involve replacement of the clutch assembly. The transmission gears are straight-cut for strength, and tend to be noisier than bevel-cut gears, still, if the noise remains annoying after an oil change, have the dealer or, better yet, a veteran Royal Star rider, evaluate the noise to see if it is excessive.
The drive shaft on the Royal Star can also make noise
if both ends are not properly lubricated; tourers have found that Honda
Moly 60 paste on both ends at about 15,000 mile intervals will
eliminate that aggravation.
Hypoid gears in the final drive can
also be noisy. Short of having the drive disassembled and replacement
shims installed, changing to a good synthetic 75W-140 lubricant will
quiet or eliminate the whine.
Splines and pins in the final
drive and rear wheel assembly can also cause noise. Remove the rear
wheel, put a thin layer of Honda Moly 60 paste on the pins, dampers and
in the drive spline, ditto with the mating spline on the final drive. I
relubricate all of these every time I change rear tires, probably more often than necessary, but it's convenient to do when the wheel is off.
