I think kevinyorks used to fill the bars with silicone or something similar to help damp them.
That was/is me. Filling bars with silicone sealant cuts vibes by a true 50%. Tested on the equipment used to test vibes on power tools. I have done this on every bike l have owned in last 20 years. You just need the sealant, gun and some pvc pipe to go over threaded end of silicone tube. Pipe needs to be length of bars - start at furthest end, pump and slowly draw out the pipe so you get it uniformly filled with no air pockets.
 
No, sorry .... all you need (apart from silicone and the gun/applicator) is some of that transparent flexible pvc pipe youcan get by the meter in homebase/bnq. Get the diameter that fits the threaded end of the silicone tube. The pipe l got was a good fit, but l cable tied it as well. The pipe is the length of tbe bars .... feed it in, then pump and slowly draw it out till bar is full. Insert any handguard fixings before it sets.
 
For the TPI I just bought a new throttle tube, lhs goes straight on the bar as normal. 350 had heated grips fitted so I cut off the grip carefully and fitted pillows. These are lock on so I imagine the previous owner cut the original grips off.
Found a tpi throttle tube/grip in the spares pile. 5 mins with a stanley knife and grip is all off. Pillow tops ordered 👍🏻
