I read through this thread but didn't see/couldn't find an answer to this question: Does anyone know the size of the FD filler bolt (#90340-14002)? I dislike Allen-Head bolts as they tend to eventually round out. I had one of these filler bolts round out on my 2013 Super Tenere and it was a bitch to remove (took several blows with a hammer and chisel), so I'd like to replace it with a regular Hex-Head bolt, like the FD drain bolt. I note that on the FJR both the filler and drain bolts are Hex-Head bolts so why the difference on the Super Tenere? Perhaps the filler bolt from the FJR will fit the Super Tenere? I note that both bikes use the same drain bolt.
Also, earlier in this thread there was some discussion about how to fill the Super Tenere's FD with the proper amount of gear oil. I put the bike on the centre stand and put a 3/8" thick piece of wood under the left foot of the centre stand, thus leaning the bike slightly to the right. I then fill the FD using Yamalube Shaft Drive Oil Exclusive (80W90?) with a nipple on the end of the bottle, until the oil reaches the opening of the filler hole, then I remove the piece of wood from under the centre stand and allow the excess oil to drain out of the filler hole. This leaves the FD oil at the proper fill level.
In my opinion, the design of the Super Tenere's FD filler hole is dumb. Why Yamaha didn't angle it upwards like they did on the FJR is beyond me.
