I wouldn't worry about the wheel bearings at all. Pay more attention to the steering head bearings, swingarm and linkage bearings.

ya.. but i think they have the same seals.

They don't have the same seals. You need to be careful when greasing your linkage bearings though, don't push the bushing all the way out of the bearings or you may risk having some of the needles fall out....then its a pain in the ass. Only push the bushing out far enough to get some grease on the needles. Then push the bushing the other way and grease the other side. You don't need to worry about the wheel bearings, They are sealed I believe. Just do your steering head, swingarm and linkage.

I have had wheel bearings go bad. Not a bad idea to pack them as well and it takes 5 minutes. I don't remove the rubber seal however. I simply pack grease between the seal and the bearings.

When I did mine I just pushed the grease in real good with my finger on the wheels, you can feel when it gets full. The little rubber seals never came out except on the linkage the ones closest to the ground when put together fell right out (both sides). It was so dry in there a few of the needles fell out of place too. I thought it was easy to put them back, once I had plenty of grease in there to hold them in place, just don't loose any.

Now I have a question: I rode through a lot of water last weekend at Hatfield McCoy do I need to redo any of these? I was planning on doing them tonight with a sprocket and chain change seems how I am working in the those areas any way.

OK while I have the thread Hi-Jacked.

One more question on jetting.

I put in a 165 main jet and the upper range runs great I tried a 170 and it felt worse so I went back to the 165. The bike would backfire like crazy when I let off the throttle so I went to a 48 PJ now it only pops a little on deceleration not a real backfire so I think that is good from what I have read. Now from 1/4 to 1/2 throttle it runs like a POS it misses and lugs forward sometimes. I think I should raise the needle (make it richer in that range) is this the correct way to move the needle or is this the wrong thing to do for these symptoms?
