So the rear fender still needs to be planned and or part sourced. The one mirror is still off and yes the hand guards are going back on. Both the rear foot mounts are coming off once I shorten down the exhaust pipe.

The valve heads need to be painted, the list will continue...along with that back tire..wow needs new shoes!

So far no oil leak from the makeshift lines, but I will have some better lines made when I find a place. It will always be in the back of my mind that they could leak or worse. I have to work on the speedo sending unit today and program the new gauge.

 

Did a little more tweaking of the tail section, I didn't want to get caught in the rain and get the wiring wet. So for now it does have a rear fender. Also got the magnet speedo working and now to calibrate it.

 

If I would have had more time I would have stopped in to visit on my way to or from Hayward last week. Would have been cool to see some of these bikes in person.

 

Yes it would have, sorry it didn't work out. Maybe next time.

Today I got a chance to take the Throttle Bodies (TBs) off the R1100 today. The plan was to do the throttle shafts as I thought they were loose and or making noise. Pulled the right side off as that one only has on throttle cable to it. Easy to pull off once you watch youtube vids. Went well but I didn't change out the shafts. There was nothing wrong with them but the TB was really dirty, I mean like they were never cleaned in the entire 80K miles or something else is going on. The TBs have a synic screw that I backed out to see what that looked like. I think I found the issue with the bike not running so well and maybe doing a little surging. That was so full or carbon or much or what ever it was. I don't see how either one of the TBs were working as they should have been. The passages for both of the air passages were blocked.

Put it all back together and started it up, didn't need the choke at all and she ran at 930 rpm nicely. I will play with it some more and see what I find out.

As for the Acewell 28xxx gauge I put on the bike, love it. I don't know if I would go with that much cost again but I wanted to try their product. I am still dealing with the fuel indicator and trying to find out if it can just sense the voltage coming from the "low fuel" on the bike. I think I will have to use the "warning triangle" on the gauge and just turn off the fuel indicator.

 

Got the bike sync done today, took it down the road and WOW. Nice to have it all cleaned up and ready for the next mod. I have to take a bit of the muffler off so I can show off that sexy single sided swing arm tire.

 

I have been noticing that this bike has been dripping a little gas out of the overflow tubes. Well I thought I should check that out and here is what I found. The two vent tubes in the pic below didn't have any clamps on them. They were just sitting on the nipples and with more gas came more pressure and drip drip!

The clamps you see are from the top of the gas cap as the rubber goes to the venting on the cap. I replaced those with something not so necessary. Being that all the connection in this pic are under gas all time you would think that it has been altered at sometime. There were compression marks in the rubber so I am not sure what had happened. I could blow air bubbles into the gas tank is how I found the leak. One of the hoses was weak and I think had a tear in it as well. We will see.

Other interesting note and this will I am sure bring up a lot of discussion and or questions. BMW has a factory coating in their gas tanks. This bike is a 96 and I would guess with no rust in or outside the tank that this would be a ethanol issue?

Got my hand in there with a rag and did the best I could do. I also hit it with hi pressure air and got as much as I could out. These bikes have a good gas filter in them, a rectangle shaped bag that is about 4" in length attached to the fuel pump and then a can filter before it hits the fuel line.

So is this just from age or is it from being in a country and area that uses Ethanol in their gas?

 

probably both

 

The missing clamps could have been caused by a DYI fuel pump replacement, and a lack of sense.
