Finaly found a gas gauge sender unit, this one needed a good cleaning, I used a ultrasonic bath and wiped the contacts with very very fine sandpaper. It should work correctly with the Acewell I have on order. The price was even lower than what I had in mind, I got it for free (well almost, I will bring them some food goodies).

I have gas taps like that one on each side.

Where did it come from? New, used?

Used of course for that price :wink: I was told it was a Kawasaki unit but I don't know which model. I asked a ocal salvage shop to find me one and they came up with a box with 6 senders in various condition, this one was the most promising size wise so I took it even if it measured open. After cleaning it, the resistance was 0 to 100 ohms which is one of the values asked for the Acewell 3250 I have on order. I think it should work out well. Now I can start to close up the tank and start thinking abou paint.

I was going to offer you a ZRX guage I have on the shelf, but it is designed to fit inside the ZRX idiot light cluster.
 
My shocks are a bit shorter than the stock units so I extended (just tacked in place for now) the lower shock mount. Doing so has a few advantages I can see:

1- the lower shock mount is closer to the swing arm pivot which means more leverage on the shock to get a smoother ride. The Fournales is an air shock, no springs, thus I could adjust the "spring" with more pressure if it is needed.
2- the shock is more vertical so it should work better up and down and it should not load the isolastics as much as the stock laid down shocks.

I am not yet sure if I will use the stock top mounting point or place the shock even more vertically than they are right now. There will of course be a plate on both sides of the top mount.

Less progressive more constant loads on shocks the more vertical plus might give back chassis stance from the shorter shocks.

As long as you don't feed the force into the cradle you just change the direction in which the cradle is pushed against the iso.

Just sitting on the bike with the stock setup will tend to put a load on the ISO towards the back as the swing arm is pulled by the shock no :?: By fitting the shock more verticaly, that front to back force will be diminished don't you think :?: That's the way I see it.

Before finalising anything, you need to check the suspension travel is close to what was provided by the OE units. Secondly if the oil capacity of the shock body is reduced substantially over that of a longer unit, the oil volume will be reduced, and as such will heat up much faster, and this will lead to reduced damping performance. None of this matters a great deal if you are building a show bike, but if its intended for serious use then it would be worth looking at getting hold of some performance units of similar dimensions to OE parts.

Too late for forethought. These were sized for a buggy so I am not worried about them heating up. As far as shock travel, even if they had less (which I doubt) by placing them closer to the swing arm pivot, the rear wheel travel is increased.

This is my final top shock mount (tacked in place)

I placed them more vertical than yesterday which should make for a smoother ride and less tug on the isolastics.

Drill multiple holes in case you want to change the shock angle. And to reduce weight, of course. :mrgreen:

The plates would have needed to be curved on the bottom to have multiple holes. BTW, having the multiple holes is mainly to adjust shock leverage without changing spring pre-load, I can do that by changing the air pressure. As for Swiss cheesing the plates, not my cuppa :wink:
