Yes, I was getting a bit of tennis elbow as well. I've had it before and it was only cured by a stunningly painful cortisone injection (in fact 10 injections) right into the painful bit. Ow.
Anyway, here is the bar end thingy.
The main big black bit is the original bar end, and you can see where it has been machined down to the correct diameter to fit into the Renthal bars.
You can also see the bolt running through it. The hole the bolt goes through is much larger than the diameter of the bolt, so you need a bush of some sort, in fact the very sort which is shown at the top of the pic. The ribbery thing on the right is from a cheapo set of Oxford bar ends, but I had to trim its diameter a tad with a sharp knife (taking care not to slash an artery or disfigure myself) to get it to slide in nicely.
I used a washer on the "outer end" of the bar end to ensure the bolt didn't get drawn into the big hole in the bar end.
As it's now warm & sunny, you could happily run without handguards if you like, and just temporarily put some cheapo bar ends like the Oxford ones in. This will sort your comfot problem out at the cost of the bars (£79 or so) and the risers (£60 or so from Nippy I think).
In the meantime, it may come to pass that I develop some properly machined Renthal fitting bar ends which slot straight in. Wont be cheap, but a complete bars/risers/bar-ends set looks likely with you choosing your own Renthal bar sweep, rise etc etc, then getting the risers & ends from Nippy.
By the way, my Renthal Twinwalls are the "Sebastian Tortelli" version - lots of different versions with different angles etc. You can also fit Fatbars as well, similar but no crossbar.
