OK Great, thanks for the clue...I sorta knew it was there, but I'm crawling at this point. I'll get better. Bike is in great shape mechanically, just needs a good going over, cleaning & a little new paint maybe...
In the shop...
I'll try again
Not quite part of this thread, but it is sortof.
What size front disc is on the GSPDs that have the caliper upgrade?
My 1991 has a 285mm( 11" ) Looking at an article on what I believe to be 1992 or 3 model, looks like it is bigger?? I know it appears to be a floating disc.
Is mine the wrong size for the caliper upgrade?
All you experts, please help.
Dude, start your own thread!
Check the part number(s) using the on-line parts fiche (sp?) at max bmw.
Iknow I should start my own thread, but this one has run off the rails, so I thought it wouldnt matter.
I checked the Max site, and yes they are a different p/n. This could be because of one fixed, and the other a floater.
Can someone "please" measure there later disc for size? Pretty please??
No pix, but helicoiled the batt neg/trans vent bolt hole last night... no problems
scraped the battery box in prep for a coat of paint to get me through a riding season or two before powdercoating....
:huh Are you copying what I'm doing? I did the same thing to my RT last night.
I found some pictures from a November 1980 magazine I scanned a while back.
Thanks Rob, that's great! don't know that I believe the bit about 370 lbs...
or the 50Hp
maybe they meant 370lbs without gas, trans oil, rear diff oil, the float bowls drained and no air in the tires
iv'e read that some manufacturers measure dry weight without the battery even. though i didn't think bmw did that.
Nothing like a little optimism?
The electric start was an optional extra on the 80/81 bikes so I suppose 370lbs with this junked and a dry bike might be plausible.
I think it's great the speed you're moving on that bike Solo. If it turns out anything like your Paralever GS it's going to be a great bike.
One of the UKGsers put his siebenrocked 1000 G/s on the Dyno and It measured 43BHP at the back wheel. The standard bikes obviously going to be a lot lower than that. I've heard 37BHP quoted.
This is it on the Dyno

Rob, that G/S is what I'm looking to do... thats a nice piece
Look at that thing jack in the cradle!
It was built by a Belgian guy and then bought into England by Johnny Boxer, he then sold it onto Wreford Miles (another UKGSer).
Johnny posted a few of the build pictures here :- http://www.ukgser.com/forums/showpost.php?p=721309&postcount=10
The frames been heavily reinforced round the cylinder head and swinging arm pivots along with a 4" extension on the swinging arm. It's a really nice bike when you see it.
The European guys spend a fortune on their Airheads and never seem to hesitate to hack them about to suit their needs..quite an eye opener.
Weissbeers (Danish GSer) mono is one of my favourites - http://www.ukgser.com/forums/showpost.php?p=1113501&postcount=54
Hey SOLO...congrads...sorry I missed out on your bike. I am just going to have to settle for that ugly 95PD Classic.
tough luck Tony !
I enjoyed the video of the Dyno test, but correct me if I am mistaken: did that old airhead take a dump at :19 and :40.
Sure looks like it. Check out the center of the engine under acceleration.
