Lacing a rim

Like many people on the forum I opted to go with an excel front rim (still sourcing a rear hub), unlike many people I have opted to lace and true my own hub and rim. I have done this on many dirtbikes and did it on a few old RS125s so I am not a novice at it. That being said it is not that difficult but there are some issues to be wary of. I will be making a few videos of the truing process and will post links. This is a photo guide to the laceup for an excel rim, heavy duty spokes and a stock hub. If you do not feel completely comfortable doing this sort of thing leave it to the pros (Woody's), it can be catastrophic to you and your motorcycle as well as the new rim and hub if you do not do it properly.

Step one, remove your stock hub from your stock rim. I had a damaged rim with no tire so all I did was squirt all the nipples down with some WD40 and let it sit for a few hours before I came back to it. I loosened the nipples with a spoke wrench and then removed them one by one. Once complete I then inspected my bearings and everything internally to assess for rebuild etc... Because I did not know the extent of use on these bearings I replaced them all. After this was complete I cover the axle hole with some tape in preparation to drill out the stock holes. The stock hub needs to be tapped out with a 0.2055 (#5) bit. This is relatively easy, I just did it by hand with a regular drill and some machine oil to reduce friction and hopefully yield a nice hole (which it did).







Once it is tapped out it is a good idea to determine which part of your hub is for the "inside spokes" and what part is for the "outside spokes"

This is the inside.



This is the outside.



It is identical on both sides. The great thing about this hub/rim combo is that with the heavy duty spokes you only have one type as they are all the same. You have 36 spokes, divided into 4 sets of 9. On each side you have 9 inside and 9 outside, with 18 on each side and 36 total.

Normally I do the inside (9 spokes) and then do the inside (9 spokes) on the other side because the spokes are usually different for the outside but since they are the same I laced up the inside (9 spokes) and then did the outside (9 spokes) on the same side.



If you notice I put all the inside spokes in the hub and checked the lace up pattern to ensure I was doing it right, it is no fun to get two sides complete and realize you messed up and have to start over. I use the valve stem hole as a reference when I start. On the picture there is a spoke then another 5 spots later. This pattern repeats itself for the entire side with the inside spokes (same on the other side too). For this rim I screwed all the nipples down till I could see 5 threads at first, I wanted to ensure I was symmetrical as well as not being too tight so I could manipulate the hub/rim if I needed too.



Always make sure you grease up your spokes, this will ensure that they do not rust together and make future adjustments impossible.



Once you have the inside laced you can go to the outside or you can do the inside on the other side (always do inside then outside, other wise you may screw yourself). This pattern is the same as the inside with 1-5. In the picture I reference it as bottom (inside) and top (outside). The inside and outside holes that are the closest wind up having 1-11 spots between them. Ensure that you have this pattern or you are doing this wrong.



Once this is done, flip and repeat.



Once you have the inside complete go ahead and do the outside, If you followed my method this side will be more difficult and may require a bit more leverage to pull the spokes through. If I was doing it again I would have went to 7 threads as opposed to 5 so I had more wiggle room.

This will be just like the pattern on the other side though.



And now you are done with the easy part.



At this point if you are at 7 threads go ahead and crank them down to 5 threads, and from here you will mark your start point with a piece of tape, the valve stem hole, whatever and begin doing half turns until the rim gets fairly taut (not tight) as the real tightening occurs on the truing stand.

Now I was sick so I didn't do the truing today and an inmate wants to watch so I will wait for him. Also I got my nice new Renazco seat in today and this little piece of farkle for my soon to be fiance.

So someone pointed out that the ring was public so I deleted it for now
