I am looking at two, hopefully inexpensive, mods soon. A stage 1 jet kit to fix a small flat spot I have and to increase power somewhat and a gear ratio change. So far in my research, threads posted on here and elsewhere, of this I was told not to look to drop my front drive sprocket for fear of slipping my chain off under hard riding and to look to make my changes to the rear sprocket. I am not too concerned about high end b/c I don't spend much time in 5th at WOT. I have always most liked and most used the SV's low end torque and acceleration. I am only looking to increase my torque a little in this mod not looking for some wheelie popping stunta bike or anything. Has anyone made a gear ration upgrade for street use? Were you pleased with it? My rear is stock so it is presently 45 tooth correct. What do you recommend going with? 46? 47? 48? I will probably also go with a 520 while I am at it. Thanks
