1978 GS750 - Brat Tracker, First Bike
« on: Jan 13, 2013, 18:47:13 »
Here's my starting point. It'll do the ton but it takes a while to get there...



Here's my first goal for it. Originally I was thinking cafe because I love the look, but I turned the bars down for a week or so, and I would much rather ride more upright. I also rode my brother's cb750 and was not a big fan of the clubmans and rear sets. My inspiration is mostly Mike Salek's cb750, but also Eric Meglasson's cb450 and the Scratch Monkee cb750.
 


So far I've got a set of progressive springs in the fork, new wheel bearings up front, oil, brake fluids, brake pads.
Aesthetically, I've put on smaller turn signals, removed the highway bars, front fender, side mirrors and replaced the mirrors with bar end ones.
I've got a few things on order from amazon and dime city to streamline it a little more (gauges, grips, tail light) and the slugs. I've got the 1" tubing, but have to wait for my buddy with a new kid to have some time to heat it up and bend the rear loop. I was thinking about laminating 3-4 layers of hardboard for the seat pan and doing the upholstery myself...
I ran it without mufflers for a couple weeks and loved the look, but it was too loud and would wake my kid from his nap. It also seemed to leak more oil out of the exhaust ports and gas out of the carbs. What causes that? Is it the lack of back pressure? (with my luck, its much more serious...)

Here is what it looks like today:



Things I need to figure out:
oil leaks
stainless brake lines up front (one piece)
fork brace?
simplified, hidden electronics
battery holder
move, adjust, shrink (?) both master cylinders - i saw an article on using a rubber tube for the master...
exhaust, pods?
oil leaks
seat pan, upholstery
headlight (bottom or side mount)
remove remote oil cooler?

Cool bike. Love the GSs with the spoke wheels. You don't see many of them. Looks like a clean bike.

definitely started with a clean, running bike... as a first time builder, that was one of my criteria... i picked the gs because cb's seem to go for so much more in similar condition

nice... i do like that tank a lot...
ive not seen those lines on a bike before, the swapped tank must sit a lot higher on the frame to create that gap?
your gs is nice... im thankful for the pic of the electrics stuffed in... i was trying to imagine it in my head...

Sweet bike man, I was gonna picture cut cafe mine, but decided against it cause I like the stock bodywork on the gs. Cut down the seat to match the bodywork better and clip ons or clubmans and a header, they look killer... IMHO

Good luck on the build, make sure you salvage what you dont need cause that bike looks to be in good shape!

i know what you mean... Mike Salek's cb750 is kind of like that.
it would make things simple to keep the panels, so i may do that for the time being and ride it with a chopped seat... doing a cafe style would make it easier because I could just move the tail section forward and make a seat to fit the new dimensions... but im not a tracker kind of person, which would be what i think it would turn in to if i kept mid controls and the moto bars with the stock tail section moved

i think my problem in trying to save as much as i can is the wiring... getting rid of the stock gauge cluster... i havent looked at the wiring too much. i was thinking about welding a slug into the rear loop and then tapping it and drilling through the stock cut frame and bolting the loop to the back from the inside rails so it.. then the guys at gsresources can put it all back together when i move on... hahaha

Mine started out in a very similar look although a 550, very similar, I had the cast wheels originally but managed to score some early spoke ones, looks way better, good luck, this is mine at the mo, not quite finished, just a few small details.

Hope you enjoy your GS as much as I do her younger sister.
