Re: Rebuild forks?

I’ve never rebuilt a fork unless,
A) it’s leaking,
B) it’s sticking, or
C) it’s clunking.

This method has served me on both on forks with 1,000 km on them, & over 100,000 km on them...

Re: Front Drum Lockup When Wet?

The "lock up" is caused by the friction material used by BMW. All you need to do is order a third party set of replacement brake shoes, like EBC or Emgo. THAT’S something that makes sense to me. I’ll put it on my list of winter tasks. Thanks! Apparently (so Google tells me) Ford Ranger pi...

Re: Front Drum Lockup When Wet?

I grew up with drums, the most memorable ones being the huge ones on my 72 laverda sf750. That old Laverda of yours was already 20 years old by the time I started riding, but I remember drooling over SFs & 3Cs as a new rider, sad that I was unable to afford one at the time. As my first bike I p...

Re: Front Drum Lockup When Wet?

Do you know if the shoe material is OEM?...Or maybe the shoes don't arc enough to match the drum. Is there a good chamfer on the leading/trailing edges of the material to help with mating to the drum? I've never replaced the shoes myself but they have the BMW emblem cast into them so I assume they'...

Re: Front Drum Lockup When Wet?

Update: after spending the night in a warm & dry garage, I can confirm that the braking action has returned to normal. I find this very odd, especially since I’ve had vehicles with drum brakes before & never encountered anything remotely close to this issue before. Perhaps our pads are compo...

Re: Front Drum Lockup?

Duane mentions grabby (and squealing) brakes... Thanks for the link. In it, Duane writes, "The /5 double leading front drum brake is a superb brake... It is, however, sensitive to humidity. The first few uses on a damp morning can easily lock up the wheel. Solution: warm it up by gingerly usin...

Front Drum Lockup When Wet?

I’ve never ridden my Airhead in the rain before but I recently got caught in a downpour & waited it out in a cafe while the bike spent 2 hours outside getting soaked. When it was time to carry on, I found the front brake had become VERY grabby, like binary. It locked right up at the first stop s...

Re: Quick’N’Dirty Center Stand Tang Fix

You could have a welder repair your old stand and save it...Were your bushings in good shape? Exactly what I was thinking. I’ll keep it on hand & repair it properly for that imaginary time in the future I do a concours restoration on it. :lol: Surprisingly the bushings were still pretty snug. I...

Re: Quick’N’Dirty Center Stand Tang Fix

Got to wonder if the holes will create a weak spot. Great question that I spent quite a bit of time asking myself before I pulled out the drill. No doubt there’s been some marginal reduction in strength, but nothing that appears to be of any practical consequence. The cross members seem to have mor...

Re: rubber boots

I learned a lesson about fork boots; don't buy 'em unless you're sure of their quality AMEN! I recently purchased boots online after carefully inspecting the seller's photos to verify that they at-least appeared stock. I was very disappointed when they arrived to discover that they look nothing lik...
