[QUOTE="Fred W, post: 1246566, member: 3828"] No. The final drive ratio is the same on all FJRs. The difference is in the transmission output to middle gear shaft gear ratio. (the middle gear shaft resides in the back of the engine cases) On first gens that ratio is 35/36 and on 2nd and 3rd gens the ratio decreases to 35/37. All other gearing is identical. Note that it is the later Gens that have the lower (taller) ratio, so the engine turns higher rpm for the same road speed on the 1st Gens (not lower). There have been some folks retrofitting final drives from other Yamaha shaft drive bikes (Yamaha VMax) to make the gearing taller and accomplish what you want to do. There are a few threads on here about their adventures. It is a subtle change at best. The FJR engine never seems to run out of rpm range out on the road. [/QUOTE]
