I used an old engine hone. it was long enough to get 1/2 way down the tube, then I went from inside to get the other 1/2. if you are doing a build and really worried about the crud/junk in the tube, just pull the r&p to do it right. why shortcut something that you obviously are concerned about? you will delay completion time by what a few hours by removing the r&p and cleaning it right? Kinda nice to know in the back of your mind that it is really clean and not just a bunch of crap waiting to push by the inner tube seal and possibly get into the gears. Or you could just slap it together, call it good. it will only mean pulling it apart later and doing it then if the gears get some crap in them. why not do it now while you are thinking of it and have the knuckle off already.
I am sorry if it seems like I am pushing ya to clean it right but its really annoying to watch, read or hear about someone that rushes through something and not take the time to do it right the first time.
I think I read somewhere :
why do we have the time to do things twice but not enough time to do it correctly in the first place?
Flame me if it will make you feel better but am I wrong?
