There's a hole in the front that the camchain tensioner bolt comes out of- cannot think of any others though.  You got a photo of this hole?

Just to update...I took carbs back off and had to replace the left side carb body cause one of the float towers had broke off. So while I had then apart I rebuilt them both to spec. Foam wrapped the stock air filter unit (after removing the old paper LoL). Also I rebuilt the brake caliper, installed new fork seals, added sum preload to forks (I'm 6'2" 240lbs), sandblasted and painted lower tubes or fork legs (whichever u choose to call it). I will continue to update as the build progresses.

The rod numbers are inked on the other side from your photo and will be just two characters, i.e. F 6. Your rod journals on the crank are 1 and 1, the numbers stamped into the machined flat area.  Then do the math.  Rod#- 1 (rod journal#) = X.  For example if your rods are 5 it will be 5-1=4. Then start with the -03 bearing as 1 and go down the list to the four bearings listed which would be 371-11656-33-00.

So in order the bearings listed go like this

-03 = 1
-13 = 2
-23 = 3
-33 = 4
-43 = 5
-53 = 6

I suppose you will want your main bearings too unless they are still good. For those you will need the numbers stamped into the cases at the front. Your crank numbers are 2 1 2 which read left to right. left 2, center 1 and right 2.  The case numbers are stamped, not cast into the bottom side of the front engine mount bosses. You have to turn the cases upside down to see them. Mine are 4 3 3 left to right. If I had your crank I would need 2 2 1 bearings left to right. The main bearings are listed the same way as the rod bearings so I would need 2 of the 341-11416-10-00 bearings (for left and center) and 1 of the 341-11416-00-00 bearings (for the right).

Hope that helps (Corrected bearing placement error- doh)

From my motor rebuild, I do remember something in that hole.  Let me research.

I think mines an xs500 c. I'm losing oil which is running out of a cylindrical hole in the cylinder which is located under the camchain.

The manual doesn't show any hole or plug so I'm thinking there must be a grommet or bung that's missing.

Does that sound right ?

Cheers.

The TX was never officially sold in the U.K. so they’re very rare bike over here, looks like we have very similar bikes, I’m looking forward to seeing yours coming together.
