Does someone have a picture or a diagram of what bolts need to be changed. ??? I think I know, but I don't want to be taking anything off I don't need to. I'm would like to get it taken care of this week end(I'm scared) :-\
wow!

Looking at the photo below, you can see the bar that connects to the rear wheel at the lowest portion.  That bar, and the associated bolts on either end, keep the brake drum from rotating when you brake.  If those bolts sheer, you're either in for a bad day (if it is the rear one that shears) or a really, really, really bad day (if it is the front one that shears.)

Those two bolts are part of my usual "pre-flight" check.  They get checked about once a month to make sure they don't have any signs of stress.

Thanks. I thought it was the on that is attached to the frame going vertical.
wow!

Read the post carefully - there is a second bolt located at the forward end of that rod.  If that one fails, you WILL pogo off the rod and crash!  You need to replace BOTH bolts.

If you have an accident on a motorcycle, it's always your fault. Tough call, but it has to be that way. You're in the right, and dead -on a bike. The principle is not to have any accident. If you're involved in an an accident, it's because you did not anticipate. Then, by default, you failed.

Yes, you want to at least check both bolts, I checked mine when the bike was torn apart.  I don't have a photograph of the second bolt at the front of that bar, but you want to make sure that neither is going to fail on you.

 jh, dont let anything on the bike scare you, everything can be made safe with just a little work and asking questions.  take your time, change those bolts , and check them about once per quarter.   Visions do not ride well on the sides, and they tend to get messed up , but with some work and a lot of friends ,it can always get fixed .

These bolts have a 10mm shank with a reduction to 8mm thread. In reality the torque applied to the nut is suppose to be sufficient enough to keep the bolt from wiggling.  The book does not call for much torque.  DO NOT replace the bolt with an 8mm. Otherwise you have left youself prone to slop enough to then cause the bolt to break. A good check is to roll forward and backward applying the rear brake. NO clunk should be heard.  If you wish to replace the bolt. Get a 10mm and grind the head to fit in the drum. The only time these break is if there is slop and/or corrosion.
looks aren't important, if she lets you play by your rules

I will take a look now that I know what to look for. As far as any clunking is concerned when applying the brake, is nonexistant. And nothing on this bike seems to corroded at all. :) As far as I can tell(aside from little hidden jems like this) my bike is fine mechanical and physical shape. :) I was actually thinking the other day how lucky I was to find this bike. I look every day on craigslist to see whats out there, and haven't seen anything even remotely close to as cool looking and  running condition for the price. $1300.00 cnd. Anyway I love this bike and look forward to preserving it in the future and love reading about it on this forum.
wow!

I just had a good look at what I'm up against, and I just have one question......... how the hell do I change the front bolt? ??? The bolts look good but I will change than anyway just so i know where i stand on time frame.

Oh.............. and to back pedal a bit.................. maybe not no corrosion, but very very little. :) :)
wow!

they say it's easier to take the peg mount off.... I wouldn't know  ::)
replacing 25 yr old bolts that may endanger your life,  for like $6 from the dealer, is a no brainer

if it ain't broke..... take it apart and find out why

To me the easiest way would be to remove that silver plate on the right side.  It's actually pretty easy for that part, think it's three bolts, one nut, two foot pegs and maybe a couple of washers.  The only trick is to watch the springs behind it (that attach to the rear brake pedal) as they like to try to pop off or move around whenever you pull that plate out.  Once that's pulled away a little it just requires a little patience (and perhaps a smidge of contortion) to take care of it. :)

If you have a drill bit small enough don't forget to drill a hole through the new bolt at the very end for a cotter pin. ;)

Ah, such fun to be out riding...

:) Please remember that it is not visible surface rust that should concern you...but the stress that these two bolt's have put up with for 25 year's :o Every time you hit the back brake pedal these fastener's are put under a certain amount of stress. We have had a couple of "The Family" injured when one has broken free...Is your life worth $10.00 :-\ Don't think about it, just change them, NOW!!!

I believe if they're tight they should be ok. That being said, they DO take alot of stress, but i think what really kills them is if they're loose. If you find them loose, dont just tighten them, take them off and replace them.
