Yamaha Virago Output Shaft Noise...Should I be worried ?!?!

[@Fireballspc]

Dear Steve's... directly from Nashville, the capital of Tennessee, the music country. I live in Brazil. Great video with explanations and disassembly of this transmission system, which appears to be very robust and if well cared for, checked and periodically lubricated with grease, these moving parts of the driveshaft (grooves/joint bearings) should last a long time. Thank you.

Ola from Nashville ! Thanks and glad the video helped some with how the output gearing and system is put together 👍. Yamaha did a good job with the design on this part I think judging by how big the bevel gears and bearing are in the gear box. Obrigado y all the best ! Steve

This is amazing, never seen before. Thank you Steve, keep up the good work. 👍👍👍

Thanks and glad the video was interesting 👍. Yep, these are designed pretty robust so unless something major happens with the oil flow, the gearing should last for many many miles first sure. All the best ! Steve

Great video on dismantling the front bevel gears Steve. I installed a 2nd gen rear wheel on my 1st gen bike. It allowed me to run a wider tire. It has a clicking sound in the differential when I move the bike around in the garage. No sound tho while riding. I’m wondering if the gears are meshing properly. There’s no slippage and it’s normal while riding. Have you done this conversion? What might be the clicking sound?

Thanks and glad the video helped some with how the bevel gear train works👍. I’ve never swapped out to a 2nd Gens wider wheel so not sure what that might affect, but there’s a small plastic plug in the side of the tunnel that the drive shaft goes through that you might be able to look into to see if the universal joint may be binding or rubbing on something.

@ thx Steve.

Dear Steve's .... Sorry for the size of the text and asking you here in this video, because it has nothing to do with the subject discussed in this video. I recently had a 1996 XV750, and I was checking and imagining from the images of several videos and electrical diagrams how the injection system of this motorcycle works, And seeing that it uses only 1 pulse coil (Pick Up) that controls the positioning of the pistons in relation to the moment of the spark in the spark plugs ...... Then several questions came to my head: - How can only 1 pulse coil (Pick Up) synchronize the correct moment of the spark, given that there are 2 cylinders out of phase with an angular difference of 75 degrees? I even thought that suddenly the magnetic flywheel has 2 elevations out of phase 75 degrees, but aligned in the same rotation alignment. on the flywheel. And if that were the case, we would actually have 2 sparks offset by 75 degrees in each turn of the flywheel, which is fine, since one of them will be at the correct moment (combustion) of each cylinder and the others at different moments during the stroke of each piston. In the case of these elevations on the external part of the flywheel to generate the pulses, does the spark occur at the beginning or at the end of each elevation? - Since the flywheel and the pulse coil (pick up) are fixed... how is the ignition timing advanced in each of the cylinders? .... would it be through the electronic module (TDI) that by decreasing the time between the pulses would calculate the engine RPM and advance the spark? If you have a video explaining this, please let me know the link. Thank you and I am grateful in advance;

Hey ! Yep, the 2nd Generation uses a different trigger pickup than the simple 1st get one that uses one trigger plate and two pickups (one for each cylinder). From my understanding, the 2nd Gen seems to trigger the spark at both the beginning and end of the pickup plate (triggers when the induction rises as well as falls) and its length is the rotation between the two cylinders. The timing advance is achieved as you said by the CDI advancing based on the time between pulses to calculate the rpms. The 2nd Gens also have an additional timing “switch” based on the vacuum that helps with popping on deceleration. The vacuum switch sits on top of the two coils at the front of the motor and also tells the CDI when the vacuum high or low to change the spark timing. Hope this helps a bit and all the best ! Steve

I may or may not have a steak knife or two out in my garage. Defiantly have a turkey baister.

lol ! Yep, my wife is constantly coming out to the garage and checking to see if I “borrowed” one of her kitchen utensils 🤣🤣
