bottom end motor noise

Post by filupsd »

How do I know if the noise in the bottom end of my 84 GL1200 is transmission or something else. I am getting harder shifts and can not shift into neutral while the motor is running. I was originally thinking Clutch but as I was talking to an older mechanic, he said it sounded like the transmission to him. Any way to know without dropping the engine.

By the way this has all happened since I changed to Delo 15W-40, And yes it is the JASC etc stuff. I am planning to drop the oil and put some Mobil 1 in and see if there is any difference.

the trans is inside the case haves situated below the crankshaft,
you have to split the case to get to the trans, the clutch is at the
right rear of the engine and can be changed with the engine in the
bike, mine is an 86 1200 sei and I installed a new clutch in my bike
the hardest part was getting all the old gasket off the case.

I would bleed the clutch hydraulic line … might help with shifting by getting full travel of pushrod. Won't do much for them noises though.

What noises you hear anyway? Loosely adjusted timing belts will flap or flop at low speeds. Rockers will also make noises at low speeds when hot if rubbing the shaft collars, was a bulletin on that years ago, noise is heard from under rocker / cam cover area.

PS .… my 1200 LOVES the Dello 15W40.
