Finally got around to checking out the ODI site and they don't make a throttle cam ( or at least don't list a useable one) for the TR.
I just replaced my bars with Pro Taper EVO Woods High 1 1/8" on Powermadd risers and thought I'd pass on a few numbers. First of all, I'm not sure why it's hard to remove the grips. Once I removed the second screw, the one on the bottom, the left grip slid right off. Drill an undersized hole. I did...9/64ths looked good...and the screw dropped right in. Well, shit. I had a slightly larger screw in stock and saved that fumble. For the second hole I drilled a 0.136" hole with a number 29 drill and the stock screw went in nice and tight. The 9/64 bit is 0.1406. A number 28 drill is 0.1405 so don't go there. If I had a set of metric bits I would have used a 3.5mm one and gotten a 0.1378 hole; I'm sure that's what they used over there in metric-land when they did it the first time.
My grip slid off just fine from the OEM bars, too. On the aftermarket bars is where I had trouble. The throttle side went on fine, but the knurling on the left side seems to cause a significantly tight grip. I had to hammer the grip onto the left side.
Not the same thing. The stock grips are lock on style. The inner diameter is 7/8" but hard plastic. The knurling on the left side of some aluminum bars increases that measurement a small amount. But it's enough to make the tight fitting hard plastic inner portion of the grip real tight. Switching to full softie grips would not be an issue. It's retaining the lock on grip that is where the trouble can be found.
I just replaced the stock bars with some Renthal 7/8 bars and am wondering how to reinstall the barkbusters. Obviously the stock bars are threaded but the Renthals are just an open ended tube. Is there a special expanding lug fixture available for the barkbusters or something similar? I'm thinking that MT bike style bar ends which use a bolt and nut to compress a rubber sleeve may work but I'm guessing that there are standard attachments available.
