Re: '78 R100s kill switch fried
Is there any possibility that the replacement battery has the positive and negative poles located opposite of the other battery? I've seen seemingly identical batteries with opposite pole locations. Not sure what hooking one up backwards might cause, maybe Rob F could enlighten us on what would happ...

Re: '78 R100s kill switch fried
Immediately when you connected the battery, or immediately when you turned on the ignition?
Was the bike running before you replaced the battery?

Re: Engine Housing Repair
Ya, what Rob F said +++ You have no speedo cable, so probably no speedo or a GPS one. but that's not your problem, right? I've seen a lot of people use a cell phone GPS app as a speedo. Works perfectly, but won't pass a DMV certification. Function: As far as gearbox venting goes, drill a small hole ...

Re: R60/5 Final Drive Backlash
FYI - With the wheel installed, check the driveline backlash with the transmission in first gear. You should be able to 'klunk' the wheel maybe an inch or so back and forth. In fifth (top) gear it will be 2 to 3 times that amount. This is normal for any manual transmission bike or car. As far as the...

I would just check it again after another 48,0000 miles.

Re: Measuring fork slider wear .
I was wondering if some of the noise was being caused by worn fork sliders. I don’t know a way to measure the diameters of the internal bearings or other way to ascertain if they worn. The age old method of 'measuring' is rocking the front axle back and forth with the wheel in the air, with the spr...

GSPD enters the 21st century...
So, my old speedo was now up around 20,000km and the needle started bouncing around (again). Took it apart, fixed the bouncing needle (again) and I tried to calibrate it as best I could with strategic needle placement. I did some speed checking with a temporary GPS speedo hooked up. It read dead on ...
