Well in all honesty I don't have a tach on it, so I am just going by what feels about right. The tallest gearing I have run on it is 15 / 44. If I could first gear down low enough I would leave it, if I have to switch 5 th gear out I will go to 15 / 47 maybe 48. When I am runnig a short course, or just goofing off I switch to 14 / 46. The bike is tons of fun on the road, and I feel much safer on it than I ever did on a sport bikes. I have had to run the thing off in the ditch at 70 mph to miss idiot cagers on the freeway, and this morning I had jo jump a curb to miss getting hit. In both cases I would have probably gone down on any other bike. I just hope I can get the gearing sorted, if not I will just keep it this way for a year or so, and look at converting one of the Honda 450's when they come out with their WR version. Thanks of posting the WR / YV ratios, that will at least get me started.
