tappet adjustment
how do I know when the back jug valves are fully closed to adjust the tappets? I was replacing the gaskets on the rear jug of a 2001 883 and we moved the bike in gear moving the original position on the valves. The result was of course difficulty replacing the rocker arm rods and finally after putting them in by loosing the bolts on the lower plate the tappets were very loud when it got started. How do I fix this problem ? I did this procedure on the front jug years back without a problem because I did not move the bke in gerar during the operation! can anyone give me some guidance my question is this, do I remove the tappets and then set the front jug at TDC and then reinstall them with the the front jug at TDC ? will this place the valves on the rear jug in the correct position (lower) to reinstall the rocker arms ? Help

There are couple good videos on youtube that will show you exactly how to do it.

This one is for an ironhead. Same principle though.

If your bike is stock, your tappets/lifters are hydrolic self adjusting. They are NOT manually adjustable. Oil can drain out of the tappets and take a few minutes of running to get them filled up again to self adjust. So the noise is normal, just run your bike a bit longer and get revs up a little, take her for spin around the block. They'll quiet down by the time the oil starts to warm up. The most common time for them to drain down is during long term storage, but sometimes they'll drain down in a matter of minutes if you have the rockers off and there's no pressure on them.

thank you so much, my dad and i were fixing my bike and he knew exactly what to do from reading the manual, but we wanted to make sure we were doing the right. however we got paranoid when i turned it on, from the clicking noise, not letting it run more than a couple minutes. also because the bike was sittin in the driveway for a couple years, which led to this situation. thanks again drum412
