1978 GS1000E Project by a Rookie

[erickson_ron]

This is the starting point for my new project. I am new to this level of project so I am looking for lots of advice. I have read a lot of posts on front end upgrades and want to find a solution that doesn't change the existing geometry and allows for better brakes and clip-ons. If someone has a complete parts list of a workable solution please let me know. I do not intend on changing the swing arm. I have a set of water buffalo spoke hubs that I may use as well.

This is the first picture of the tear down. I have found out that the tank I have is full of a nasty coating and the tank has lots of bondo. If anyone knows where I can get a tank or what other tanks will fit without modifications that would be a plus.

This is the inspiration I am using for the build. Love the stance just need to make it mine. Smaller front fender, custom side panels that fit in the triangle and very simple electrics.

Well, for the front end you can just buy clip ons for the stock forks or use clubman bars and do Salty Monk's brake upgrade. That will get you decent brakes and the bar position you want.

Just for curiosity, what is your budget and what is your estimated time of completion? Good luck can't wait to see the finished product.

 

[erickson_ron]

Overall budget is $8k plus the original bike. Hope to have it finished by Christmas. I have a guy in Dallas rebuilding the motor, tranny and clutch and that should be done by the end of August.

I would have sold you mine for half that.......

 

[erickson_ron]

That is beautiful. Did you do Salty Monk's brake upgrade or swap front ends?

 

[Guest]

Stock 78 forks, sonic springs with emulators and Saltys brake upgrade.

Well final first tear down as it heads to the blaster tomorrow so we can inspect welds, add bracing and take off tabs no longer needed. Any good info. on removing bearings from swing arm? I assume they are pressed in.

Too many bikes not enough garage!

I used a propane torch to heat the swingarm pivot tube, then knocked them out with a hammer and punch. If you use oxy/acetylene instead be extremely careful you don't melt the swingarm.

Too many bikes not enough garage!

I have 3 bikes in my garage in about half that space, my sympathy is pretty minimal.

Will a 1980 GS1000L tank fit properly without mods to a 1978 GS1000E frame?

Pretty sure the answer is no. A '80-'81 GS750/1100E tank is a direct bolt on though and they are somewhat available in the marketplace.

Not saying you don't have a well thought out plan....but from my experience, I learned to wait a while before blasting and prepping the frame till you have all the new components designed and mocked up in place.
Some tab or bracket always needs welded on for some accessories or custom peice, or something ground smooth for clearance or fitmental.
Plus all the test fitting seems to bang up the new finish.
I know you only said you were blasting , detaining and inspecting. Just sharing that I learned don't be too quick to get all painted up pretty.
Looks like a great project, keep the pictures and progress coming.

 

[erickson_ron]

Good thoughts loud et. We are justing cleaning up to inspect welds and start all of our mock ups. Definitely won't go to powder coater until all is fitting to our satisfaction. I have had bad/cracked welds powder coated before because we didn't get a good inspection done first. Are there any weak areas on these frames that people tend to gusset or brace on these bikes?

Does this look like a 80/81 1100E? Sellers seems a little unsure. Thanks

Yes, that's the one.

The tank you have is a valuable one... don't cut it up even if it's in ropey shape!

The 1100 tank on the same bike... bit more inspiration for you!
