moshe_levy Posted April 6, 2007 Share Posted April 6, 2007 All- Today I whipped out my new Twinmax, adjusted the valves, and attempted a TBS on my GF's '04 R1150R. The valve adjustment was straightforward, but the TBS less so. I used the "TBS for Dumnmies" article from advrider for reference. Upon initial inspection, the right hand Big Brass Screw was "normal" at 1.5 turns to seat. The left, on the other hand, was barely 0.4 turn before seating. Instructions said a deviation of more than 0.5 turns is uncommon and cause for concern. Synching at idle was easy enough. But at 3-4k revs, the best I could do was get the needle to waiver between "1" and "2" to the right on the Twinmax. Everything would zero back out at idle. I could not get it to zero out no matter what I tried at revs, though. Admittedly, I gave up after about 30 minutes, and there's plenty of time to get it right before the big trip in May, but I'm wondering: 1) Why the disparity on the Big Brass Screw position? Last TBS was at the 6k mark and done by the dealer. 2) What am I doing wrong? As I left it, I had messed with the Brass Screws and right hand throttle cable to the point where both Brass Screws at 1.5 turns out. It's definitely better all around than when I first started, but not perfect yet. Any help appreciated. -MKL Link to comment
