If I was racing a late model XS500 on the track, I would chuck the balancer and related junk in the trash can too....

If I was restoring an early model TX/XS500 because the historical engineering importance of the first ever production 180 degree twin with twin OHC, 8 valves and balancer shaft damping appealed and intrigued me... I'd probably leave it in....

Not sure whether I would claim the laws of physics and engineering did not still apply either way though, maybe just my perception of the lack of, or addition of, increased vibration if it was in or out....

I apologize for the (perhaps) stupid question, but will I have to drain the oil prior to removing the left side cover? Ordinarily I would not ask this, but it appears that the chains are kept separately from the rest of the crankcase.

I have been giving a second life to an old TX500 my friend left me for cheap. I just changed the oil and finally got it running and I can hear very loose chains rattling around in there. It's time to check the tension, but I don't want to ditch the brand new oil! Cheap, I know. But being wasteful is never good.

Just thought I'd ask.

Cheers.

The chains and generator flywheel are oil flooded behind that cover I am afraid.  In fact you will notice the oil level dipstick is mounted in the cover, so there is oil in there!

You could try tilting the bike over onto it's right side, which will allow the LH cover to be removed without draining the oil....

Thanks for the reply!

I think I will try and salvage the oil as best I can. I'll make a judgment call once I see how clean I can keep it. In putting the bike on its side, I'm liable to screw it up and damage it somehow, I can feel it.

Cheers!

If anyone still come here I need help with my 75 xs500 where I dont have the tensioner shown in the pictures above and am wondering if I will have to take more apart to get to it.

So after reading this how to I though Iíd check my balancer chain and itís certainly got too much slack. However when I opened my XS500C I was presented with this setup which is different to whatís in the write up here. It looks to me like there is nowhere to use the screwdriver to make any adjustment?

Whatís more after I loosened the hex bolt and went to tighten it back up I got that dreaded feeling where it gets tight then loose again, tight then loose again... so looks like the thread is now ruined.

Not a good day... thinking now perhaps itís best to ditch the whole balancer setup.
