Touratech tank install on XC, problem

I bought a used TT tank for my XC. I ran into an issue wiht the install of the front tubular support:



There are square brackets that slide together to hold the tubular frame in place around the fornt vertical frame tubing. These bracket are supposed to center around the horizontal cross tube that is part of the frame. However, there is a big goober of weld that you can see in the picture above that prevent the brackets from centering around the horizontal tube. this means that the square bracket will not seat into place since the weld of the horizontal tube interferes.



Now the square bracket will not clamp together.



Has anybody run into this before and if so what have you done about it? Grind the weld, force the bracket together. None seem to be a good solution. Maybe grind the square bracket somewhat to allow it to slide around the weld?

How critical is the location of this tubular tank support. I assume having it 3/8" lower will not matter?

If I remember correctly, I basically muscled it together using a pair of vice grips, lots of colorful language, and elbow grease...

I squeezed the clamp together with the vice grips while screwing the bolt & nut together. I thought about grinding some of the weld off to make it easier but I could not find my dremel tool and needed to finish my install...

Eh? Touratech tank install on XC (my fix)

I didn't have quite as bad a weld on mine but did end up doing the same as macadamia, a set of vice grips and then bolted it together.

I also found it a little nicer to start on the side with the weld problem giving me a little more shift and then did the other side and it worked better for me.

And having it 3/8" lower, might make fitting the tank to the outside tank mount point quite a bit more difficult, I would recommend finding a way to make it work where it is designed to go.

Good luck.

Well, that is what it took, lots of the middle one, plus a grinder to grind away parts of the locking brackets that were interfering wiht the frame weld.

The tank is now installed and I am working on the fuel lines. I need to find some heat shielding where the fuel line runs close to the exhaust, or maybe turn the fuel valve around. Something for tomorrow. I am thinking of putting an inline fuel filter before connecting it to the bike fuel tank vent. If I get one large enough it should not interfere with fuel flow... I think. I see others have worked on the guts of the fuel tank vent. Why have you done that?

Lastly, is there anything to be done withthe filler cap on the bike fuel tank? It shoulkd be vapor tight, so nothing to be done there, right?

The guts of the fuel tank vent is a check valve, allowing the vapor out but nothing in... If you don't remove it, the TT tank will not flow into the stock tank. The stock tank has the fuel pump in it, so as the bike uses fuel, the stock tank draws down creating a vacuum on the fuel line attached to the TT tank via the vent cap. As the pressure lowers, the fuel will flow to keep the stock tank filled.

The guts of the vent fitting - it's a spring loaded check valve...




I did find one issue with this setup... If I was going faster than about 75-80 mph, the bike would drain the main tank faster than the vacuum created would draw fuel from the TT tank and I'd run out of gas with plenty of gas in the TT tank.

Also, I would only keep one side petcock open at a time. On my long trip last summer from Southern California to Chicago and back, I'd stop about every 100 miles and swap petcocks, and get gas about every 250-300 miles.

As for the fuel filter, I do not recommend it as any additional items in the line between the TT tank and the stock tank can slow the fuel delivery. The stock fuel filter still works fine within the stock tank with this setup.

The TT tank now becomes the high point of the fuel system and that is where the fuel vent will be located. Just use a piece of fuel tubing and not one of those stubby check valve vents. This also hampers the flow of fuel to the stock tank.

And, finally, I plumbed the TT tank as such: the left side petcock was attached to a tee on the right side, right at the right side petcock. From one side of the tee, I fitted a very short hose to the right side petcock, and from the other side of the tee, I ran a hose vertical from the tee up just behind the radiator, then followed the contour of the air box, then back down along the frame rail under the seat to the stock tank fuel vent fitting. I ty-wrapped the hoses to the top of the TT tank bracket under the radiator, and have had no issues with hot fuel lines or any scorching.



The stock fuel filler needs to seal tightly, to ensure the fuel pump can create a vacuum in the fuel system. If there is any air in-leakage, it will not vacuum drag the fuel from the TT tank to the stocker... When I first completed this install, I noted some weepage around the seal at the fuel vent connection and also around my stock fuel filler cap. I replaced the fuel cap and the seals around the fuel filler and also the vent fitting. They had dry rotted and would not seal properly. After replacement, it worked like it should have.

You can see the dry rot cracking on the lower right side of the hexagon-shaped gasket under the fuel tank vent fitting...


If my explanation is confusing, I can take some more photos of the install and post them...

That description was perfect and very helpfull. Much appreciated. I will try to finish the project tomorrow. It turned out to be more work than I expected due to poorly fitting TT parts, but it will be worth it when I am done.

Curious: if the tank vent is a check valve that only lets vapor out then what on a stock bike lets air in the tank as it empties out? That has to happen thru the gas cap then? But the gas cap only lets air in at a substantial vacuum? Or at least more of a vacuum then what is needed to suck gas from the bottom of the TT tank.

Thanks again,

KP

That's the benefit of this forum and the experience of other riders and owners of the same models... I would have had tons of issues if Tim (TBarstow) would not have shared all he did when I bought the TT tank from him. He and I talked for over an hour about fitment, issues he had, solutions to those issues, and other miscellany.

I am glad I could help...

Im interested and a little skeptical of this description because my self and at least five other people I know have xtanks which draw fuel through the breather valve into the main tank as the main tank empties. To plumb them in all we do is pull the breather hose off the tank breather ( that white hexagonal thingy in the photo) and push the fuel line off the xtank on instead and it will syphon. No need to fiddle taking bits out of the breather valve.
Why does the TT tank require this extra step?

Having rethought what I described and what you are stating above, I was mistaking in my explanation of why the breather check valve needed to be removed. Thank you for pointing out my mistake.

The tank vent check valve does not need to be removed to allow the vacuum drag to occur from the TT tank to the stock tank. I believe it was recommended to me to remove the check valve to ensure free flow, as in no obstructions that could possibly hinder the flow gas.

I made my own 1.75 gal tank that looks and fits similar to the X-tank that's plumbed off the top of the factory's vent, same as everyone else's is plumbed and have only had one fuel flow or transfer issue in 16K miles. My only issue was due to the rubber gasket between the factory gas tank and the locking gas cap started to leak a little. I first noticed a little fuel leakage on the side of the tank after the bike was topped off. Then one one occasion the low fuel light came on at around 100 miles and no fuel was pulled from the accessory tank. That gasket leak at my main tank filler "broke" the vacuum that pulled fuel from my accessory tank as the main fuel was used. A quick tightening of the bolts that hold the filler in place brought everything back to Golden, and all has been well ever since.

Nice tank!
Any details? What did you use etc.
Thanks!

Yacugar is also a Dutch motorcycle suspension firm, like Hyperpro, but they are not quite the same people - tho much of the componentry is the same.

KTM bought Dutch motorcycle suspension firm, WP, from its founder Wim Peters back in the late 1990s, and in 2006-2008 moved the production to Austria. Many of the Dutch suspension engineers who used to work at WP in Holland didnt want to relocate to Austria, so they stayed in Holland and decided to start their own motorcycle suspension company - which became Yacugar. As it was too expensive to buy all the tooling and metal working machines, and because Hyperpro already made their own high quality components in Holland, they decided to source their components from Hyperpro. So a Yacugar shock and Hyperpro shock will look the same. Same reservoirs, same piston rods etc.

Ok thanks for the complete info. Not the same people, I believe you, but that is a different story than the US rep told me, but that still explains why all the components look the same. I was wrong about the progressive vs. straight springs however, it is unrelated.

My Yacugar is working great so far, and I never could get my Wilbers to even stop bottoming even after going up 3 spring weights. But I imagine other Wilbers work fine, just don't know what was going on with mine.

anyone using the renthal twin-wall handlebars? Are the 1 1/8's a straight swap with existing controls?
thanks....
