I resolved the problem. All it needed was a little bacon grease and it slipped right in.

Welcome, steven. How about posting a photo of your bike tangled in this dilemma?

The front hooks fit under bumpers on each side of centerline, the rear posts drop into the grommets. Bingo. If you don't have clips, it might ride high. The clips can still be purchased. Having the tank connected at the rear will make the side covers more secure in their mounts. There could be cables, insulation or hoses interfering with lowering. Are hoses attached to the two rear ports? Are the fuel hoses in the front keeping the tank from lowering?

Why was the tank removed anyway?  :yes   Maybe somebody will move this post to the Workshop where it belongs. In the meantime, what's the story?

The Motobrick Workshop / K75 fuel tank reinstallation
« Last post by steven1969 on Today at 06:12:35 PM »
Hello everyone.
Any tricks or tips on how to reinstall the tank on a 1987 k75. Can't get the 2 bolts on the back of the tank to sit all the way in the rubber grommets.
By the way the 2 clips that hold the tank down didn't come with this bike.
Any help will be greatly appreciated.
Thanks.
Steve

Is it fair to assume that the bike hasn't ran properly for a long time and that is the reason(among others) for the incredible price?

If so, my recommendation is to go through the entire bike front to back getting everything right before taking it out for a ride.  This is a  bike with a troubled past and there is nothing you should take for granted. 

If the bike has sat unused for an extended time, the old fuel has probably built up a lot of varnish in the injectors.  You can take them out and send them to be cleaned, or possibly dump a bottle of Techron fuel system cleaner into the tank.  Run the engine for a couple minutes to circulate and mix the Techron throughout the system.  Then let it sit for a few days and restart the engine.  Depending on how bad the varnish is, it may take a couple weeks of doing this to get things loosened up.  If they still don't work after two weeks of circulating the cleaner, you will need to send them out to be professionally cleaned.

If you haven't drained the tank of old fuel, do it now and replace it with two gallons of no corn premium mixed with a bottle of Techron.  An easy way to drain most of the fuel out of the tank is to pull the return line hose from it's spigot on the tank and put it into a container so it can't spray and splash all over the place.  Start the engine and let it run until all the gas is pumped out and it quits.

Since this is a "new" bike, when you have the tank empty, you should remove it and use the opportunity to do any service that requires the tank to be off the bike.   This includes cleaning all the connectors under there, especially the ground connections on the frame backbone.  Then you can drain the cooling system and put in new coolant.  It will also be a good time to do some improvements like an Eastern Beaver headlight relay harness and a manual fan switch.

Tank removal can be done without removing the main fairing.  The hardest part is disconnecting the fuel lines which should be replaced anyway.  You don't even need to remove the seat, although it isn't very difficult, and makes tank removal even easier. 

Once you've done the under tank stuff, get the tank back on and start circulating the Techron fuel mixture while you address everything else.

It comes with a monogrammed, titanium gin pole to aid pick up when it's dropped.

Please forgive me if you have already answered this.   Is this a new to you bike?  Did it run properly for you in the past, or did this problem come with the bike?
The bike was pre-flogged by others before he plopped down cash for it, Gryph. He's had it a few weeks.  Some of the sordid details can be found in his first post.
