[QUOTE="ionbeam, post: 282106, member: 277"] I see this as two separate issues. Drive line lash is a mechanical factor; it is there on all FJRs. Even if there was no abrupt fuel issues, coming on and off the throttle will give a little driveline bump due to lash. Separately there is the rude Acel/Decel fuel management that causes abrupt engine rpm changes. Even if there was no driveline lash this abrupt fuel management will give you a rough ride. If you do a search you will find that the Acel/Decel fuel management is recognized as a real problem and it has been pretty well documented. Putting it all together leads to very rough throttle transitions, worse on some bikes than others. [/QUOTE]
