I am currently drafting auxiliary aluminum fuel tanks for my RD07. On the left side, the mosfet regulator can easily be moved inside the toolbox under the seat. What about the coolant reservoir? Has anyone found a different location? It can't be moved to where the RD03 coolant tank sits because of the oil cooler. Unless I move the oil cooler at the front.

Please let me know your hack. ;-)

TIA

I'd like to know how you solve it, too. I'd thought about doing the same to my RD07a, but for different reasons. The idea I settled on was to move it to the underneath of the tail fairing, in between the frame rails, but it relied on getting (or making) a reservoir to fit. And I haven't got around to it yet....

In my case, I wanted to experiment with some closer fitting panniers. I can't abide the wide, chunky boxes mounted up high; they aren't good for stability, filtering, they look clumsy, etc. Personal opinion, I know. So I'd looked at removing the side panels, moving the coolant reservoir etc, and mounting the panniers close to the frame. It would also need an S-shaped link pipe on the exhaust, to get the can below the pannier, but this would give a much neater and more symmetrical mounting arrangement. I've seen it done on a RTW bike and it looked very tidy.

One day......

So far, what bugs me is the key actuator for the seat release latch. I might have to cut it out, and pull the latch with a simple wire. The voltage regulator can easily be moved into the tool box. All that remains is the coolant tank, which I know can be moved.

On the Transalp, I took the pull cable from the lock & mounted it somewhere partially hidden but not too difficukt to access.
Very handy abdceffective it was too.

Isn't there room inside the fairing behind the rad for the header tank?

I have waterless coolant in my RD03, it never boils so you don't need the overflow bottle.

Bit pricy but definitely worth it, one of the best things Iv done with my bike.

Doesn't waterless coolant expand between say 0* & 100* either?

It expands but very very little, not enough to boil over.

Another plus is you never need to change it.

Also no water so It doesn't corrode your system.

And I gained about 5-8mpg after installing it, Apparently due to better cooling witch leads to better combustion (because of the lack of steam & pressure that comes with water)

And..... if you sell your bike you can drain it and reuse in another bike :D

You run a closed cooling system?

The coolant expands, where does it expand to?

Pressure will quickly build in a closed system completely filled with liquid. You don't need much expansion.

Low vapour pressure doesn't mean low expansion.

The coolant system is not closed, the pressure cap is still on the radiator and if it expands it will flow out and down the pipe onto the ground. I have filled the system almost to the top, there is about 1cm air gap to allow for expansion.

The overflow system still works, there is just no overflow bottle because it's not needed.

I had similar concerns, wanting large pannier storage but without the width. The majority of the width of most setups comes from the OE exhaust and bulky rear side panels. I fitted an Arrow Dakar exhaust and chopped the panels where necessary, but left the RegRec and coolant bottles in the OE positions. I used a pannier rack with a cut-out for the exhaust (Heavy Duties brand) and modified both sides to bring inwards by around 50mm each side.

Here's a pic (cardboard top box is a mock-up only for one I'm thinking of getting made!).

PS: Sorry for the mini thread hijack.

Looks tidy. Do you have any pics from behind, to get an idea of width, exhaust position, etc? Ta.

I'd intended to remove the side panels entirely, rather than cut them, and relocate the reg/rec etc; shouldn't be too difficult, but might need some rewiring. The coolant header is shaped to the frame though, so a different tank needed, depending on where it goes. The waterless coolant is an alternative solution (see what I did there?); might think about that, as it would be a lot easier.

The exhaust is the main obstruction, and the S-shaped link pipe would sort that. Once that's done, the panniers could almost mount to the under-seat frame rails, which would make them much narrower. Yours look like they are pretty much there; got any pics of mounting details?

With ethylene or propylene glycol head temps will rise because it is less efficient at cooling than water, has a higher viscosity, can carry less heat than water.
If you are getting more mpg that's good so long as your engine isn't suffering.
I can get more mpg by leaning out the mixture at the carb, if you do it by raising head temps the results will be the same.
What is your mpg? Are or were you running rich before?

Here's a few more pics that I've just taken for you. Let me know if you'd like any more.

I used "Evans waterless coolant" it doesn't contain any water or ethylene glycol.
Before switching to Evans my bike was running perfectly, spark colour was normal, air filter clean. Choke not sticking. Etc etc... Everything was stock OEM.

I track my fuel by KM per Litres.
my fuel economy was 12 to 14 km per Litre. After using Evans it has gone up to a lowest of 15kpl and highest of 21kpl.
I normally get 17 or 18kpl.

I should mention 95% of the time I ride two up with about 70kg luggage.

Thanks for the pics, Matt. Interested to see what you've done with the steel rack frame; I've always thought the standard plastic one was a bit Mickey Mouse and am intending to do something similar. I'm not ready to cut up the side panels yet, so I'll have to find a slightly different way of mounting the panniers. But they are obviously much narrower than the usual setup. Any idea what their full width while fitted is, compared to the handlebars?

Interesting murals, very, ermm, distinctive.;)

I looked at a full custom rack but in the end decided that modifying a pre-made one was more economical - mostly because I wasn't doing the welding myself, and the labour time was much lower.

The width is 88.5cm. My handlebars, with the bar end plugs removed and handlebar guards fitted is 89.0cm. So, I have 'whiskers'!

You may notice also that my panniers are significantly deeper than any others on the market, that I have seen at least. To be honest, I'm not sure why this isn't more common. It gives great storage volume with the weight low down and a narrow pannier width. As an additional bonus, the bike sits relatively upright when dropped, making it easier to upright.

The whole bike is something of a wacky work of art in progress. I'm travelling around with the bike at the moment and inviting people along the way to contribute by adding to it. One of my more mature friends added the pink member on the rear of the tank... We will be painting the panniers with something more silly in the coming weeks, watch this space!

They are all blends of it, eg and pg, even the prep fluid is eg.

Propylene glycol is the stuff people vape and rarely appears on msds.

Now to convert some sums
Wow that's news to me. I had no idea what was inside it. I don't think a lot of people would know that eg and pg is inside.

One of the videos I included above (Delboys garage) he talks on about how it doesn't include eg and it's toxic free etc, but what's more interesting is that a sales rep from Evans was helping him with that video...

I think my bike runs the same if not better with Evans, theres no pressure, no boiling, engine temperature never goes to high and fan rarely comes on. And Iv been in traffic in +35. It's been on the bike now for about 23,000km

Its good it works for you, I'd just say that high head temps won't transfer to high coolant temps with a less efficient coolant, which compared to water the glycols are.
Good fuel economy.
