advance unit

So I have an issue with my revs sticking higher than normal. One thing is, if I blip the throttle up to 2k and let it close, it will hang and suddenly want to go further BY ITSELF and reach up to 4k RPM. This is both in neutral and idling, and in any gear with the clutch pulled in. I did some...

Hi XS650 fans, I am new here but i ran out of search options on google. I have 1892 XS650 that i bought as a barn find. This is my first xs650 so there is some learning curve for me. I have two manuals and both say that i have to remove the ignition advance unit, the rod and so on. I want to do...
