Newish idea to mount stock gas tank

isn't the problem with those the studs leak at the tank becase of spotty welds? If thats so it may not matter how well you mount it?

I hope I never have problems with the studs breaking due to vibration. One tip that I used on my installation is placing small square rubber pads between the tank and the tube. I actually just cut up the original handle grips which already have a curvature to them. So far, no problems.

You are deffinately NOT alone. I have tried several things to mount, and fix these super awsome (sarcasim) penut tank studs. I had at one point thought about welding brackets onto the top tube so that it would be imposible to bend the studs by tightening the nuts. I have abandoned the idea due to the fact that I really want the keg style behind the seat and don't want to ruin my top tube when I make the swap.

As far as vibration goes, I don't think rubber helps. I have used a cut piece of tire, the square pads that came with the kit originally, and innertube (the length of the tank folded ove 3 times so it was thick and soft). My bike isn't a vibration monster, in fact its pretty smooth till it hits about 30mph. Still trashed 3 seperate tanks and every time I patched the leaks, about a day or so later of riding the patches fail.

want to know the secrete to keep your tanks from springing leaks from the mounting studs? take two chunks of heater hose, cut slits in them and put them on your top tube, and mount your tank onto that. it isolates the vibrations. never had a tank crack or start leaking with that.

That's a good way to work around it.. Nice work.

Form follows function. You can always make it pretty after testing.

Necessity is the father of invention!

that is what I did for that problem

One easy and secure mount is to use two muffler clamps welded to the stock tank studs. I used this method on a ONEX 29'er and it worked great. I got a weld on each stud at least 1/2 inch long so it was nice and secure.

i've had leaks in 2 tank from vibration the tanks got leaks around the studs, i've even brokes the tank mounts, this is my solution. get some flat steel cut it to size and bend into an L-bracket, make 2 for the front of the tank and 2 for the back, drill a hole in the end of all the brackets then cut a piece of steel to run from the front bracket to the rear bracket, drill a hole in each end and pop rivit them together, drill 2 holes in the vertical side of the L-bracket and pop rivit them to the top bar of the bike, use sticky backed velcro cut to length then stick the 2 halves of the velcro together( the velco sides not the sticky sides)peel off the backing from one side of the velcro and stick it to the bracket, clean the bottom of your gas tank then peel off the backing from the top side of the velcro, line your tank up exactly where you want it ( you only get one shot at this so take your time) then press the tank in place pushing down firmly to assure that the velcro is stuck firmly to the tank and bracket. now you have a removable tank that won't slip( i'm using a 1 gallon tank that is very heavy when full) or leak. as you can see from the photos this is an older build with many miles, you can see just how many times i failed before i came up with this solution. hasn't leaked since.
