About time ACC was privatised, then I would be happy to have private medical insurance. Paying around a couple of grand levy's now and dont have any choice except to walk everywhere.

To baffle or not. What do you think should hold about 15 Ltrs

Baffling would help with structural rigidity, especially if this is going to be a metal tank.

I don't think rigidity is going to be a problem its 1mm panel steel just thinking of 15Kgs moving around down there ie: under brakes or side to side

That's why I said about baffles introducing structural rigidity. It's all central, so slop will be fine. My nylon tank is divided by the frame spine, which gives some baffling, but there is a heap of potential movement there. But nylon can move - steel not so much... 15ls is not much though

You could put some evomx foam baffle cubes in . Got them on the klr with the big tank and they definitely work.

**GSers** · 3rd January 2013, 22:03

So your saying you dont feel the fuel slopping around at slow speed. ie: changes in bike weight feeling.
I wonder how they would stand up to being put inside the tank before I welded the top in place.
I will google it tomorrow and check it out. Thanks

Hey Woodman, that looks like the stuff I am after save's adding any more metal / weight to the tank I think I should be able to push that through the filler pipe hole.
Did you buy it in NZ (where) or bring it in from over the seas?
Thanks

I got it through work, still have a box on the shelf on clearance at the moment. I have 1.5 boxes in my tank (28 litres) which pretty much fills it up except for a couple of litres at the top.

If you want some it can be arranged no worries.

Day in the shed couldn't find fittings that I wanted to make these tanks work so have had to make them.

1 evomx foam and inspection
2 old petcock YZ tank
3 replacement for petcock to 3/4 hose
4 outlet to weld into the bottom of the tank

Hey Woodman how is that nose going? Hope your healing OK
Bike riding next weekend wof rego go for a ride.

Nose is healing up ok thanks, stitches out last week so now just waiting for it to heal up. My nose will be a different shape I think.
