Gas Tank

[Dreamrider]

I have been doing a lot of searching and don't find a thread on modifing the R1150R gas tank. I have tested my gas tank on my 2002 R1150R and I have .8 to .9 gallons of gas on the left side that never gets used. I plan on drilling a hole in the left side and installing a blukhead connector making room for a cross over line from the left side to the right side of the tank. I was looking for anyone else that has done this, or if anybody has a better idea?
I saw mention of CycleRob and tank modification but could not find the thread.
I ran out of gas one time and leaned the bike over to let the gas flow to the right side, when I got to the gas station I could only get 4.2 gals of gas in to the tank.
I do a fair amount of LD riding and carry a aux gas tank mounted to the back of the bike for the long trips. But when don't have the aux tank I want access to the rest of the fuel for that little extra millage.

Is this the mod you were thinking of?

Everytime I fill up, I spend ages trickling the last few drops into my tank - and each time I swear I'm going to do the mod. Maybe this winter I'll find the time.

Does anyone have a picture of the filler neck with the holes drilled. Would like to make sure I am drilling the right part.

That helps get the tank full but does not let you use the trapped gas in the left side of the tank.
When I install a cross over fuel line I will make sure I take pics and give a report of how it is working for me.
At a motorcycle rally I discussed this with Paul Glaves and he agreed that a cross over line was the only way to use the gas trapped on the left side of the tank.

I remember reading about one in which a bit of brass tubing was brazed on to connect the L/R lobes. Thought I bookmarked the site but can't seem to find it. Have you checked the archives here and on the IBMR site?

Recieved this post on another web site and wanted to share it.


Before you start drilling holes read this thread http://www.advrider.com/forums/showthread.php?t=2490

I made my own up with tygon line and brass fittings covered with heat shrink. Works well - a hell of an idea!
Picture below is for a GS tank (Heatshrink not installed yet on brass ends to prevent scratching)
Be sure to drill filler neck low enough to allow lid to close.

Not sure I follow the approach here.
Does the modification wind up bifurcating the line, with a separate hose then inserted into each lobe?
Would this be the same mod on the R as the GS? The fuel pump, float and pickup on the R are accessed via the side plate, no?

Interesting concept if it'll work.
