We are generally discussing the fact that his rear wheel locked up.Originally posted by blowerbike View Post
We then progressed to some of the common causes of rear wheel lock-up.
One of the reasons could be lack of lubrication in the driveline, specifically the secondary drive (the front sprocket area on a chain-drive bike).
Another reason (which could happen on any bike) is that the compensation port in the master cylinder is blocked, not allowing fluid transfer.
As I mentioned in post #16, if that port is not open, the only place for expanding fluid to go is behind the pistons, pushing on the pads, locking up the rear wheel.
Did you follow this time?

yes but i would have thought he would have popped off the caliper to see if the wheel would then turn.Comment

Yeah, you would have thought that and I would have thought that, but he evidently doesn't know to check that.Originally posted by blowerbike View Post
You can also just loosen the bleeder nipple to release any pressure that has built up.
As tkent asked, "what was hot?". That is most-likely where the problem lies.

Yes... you did it for me remember?Originally posted by Steve View PostBut did you rebuild the master cylinder?
Even more important, did you clean out the compensation port (which can be done without rebuilding the master)?
If that compensation port is plugged, it will not allow fluid from the caliper to bleed back into the reservoir as it gets heated from the friction of the pads rubbing on the disk. Since the fluid is expanding and can't get into the reservoir, the only place it can expand is to push on the pads, which can lock up the wheel.

Yes, I do. (I even see him at work, occasionally.Originally posted by blowerbike View Post
)
And yes, I cleaned the master cylinder.
I have worked on more than one bike since then and I have slept since then.
"Memory" is such a wonderful concept, I wish I could remember how to use it.

OK got it apart. The secondary drive was full of black water......... yes water and dirt
WTH? Dont ask me... that is just something I never check because I assumed that the crank case oil lubricated the drive shaft. Well, that sucks. But at least I didnt destroy anything and my bro is OK.
So I need a secondary drive assembly for 850-1100 shafty... anybody?Comment

You want one for a 1000 or 1100, not one for the 850.Originally posted by BIG_brother View Post
The ratios were different.

Clean it out as good as you can. Long Hemostats and rags maybe to swab as much crap out as you can??? Put a new oring on the unit when you install it. Rcheap lesson to learn all things considered bro!!MY BIKES..1977 GS 750 B, 1978 GS 1000 C (X2)

NEVER SNEAK UP ON A SLEEPING DOG..NOT EVEN YOUR OWN.
