So my guess is it adds oil capacity by filling the heat-sink with oil, which is then cooled by the increased air flow. It looks like you then have the ability to bleed the heat-sink as it becomes the highest point of the system.

and then a heat sink solution like this which is a simple stick on item:

Then lastly, an air duct solution:

I wonder if and how much these additional reservoirs change the brake feel. would it make the pedal spongy?

As long as they are rigid inside, the theory of hydraulics suggest that is should make no difference to the feel at all, but I would try and find someone who has tried them.

The in-line banjo ones mentioned first seem to be the most commonly used.

What about trying a different fluid Digsta...one with a higher boiling point or get a better front brake perhaps

I have put the highest temp boil stuff in it now. maybe I will just ride up hill from now on.

Digga1111 - Brake Fade

[QUOTE=digga1111;22645429]I have put the highest temp boil stuff in it now. maybe I will just ride up hill from now on.

Have similar issues on occasion here in Vic on very long/steep down hills ie Billy Goats Bluff track dropping from 1400m to the river in not many Kms.
Tried a variety of brake pads but same issue.
Put DOT5 fluid in and still the same issue (pedal loses pressure and needs to be pumped to get any reaction).

Shortly after purchasing the XR I had some significant brake fade front & rear.
Fixed the front with an oversize BRAKING rotor, replaced the rear pads and removed the wear indicator (thin metal insert between pad and piston) as I have removed this on other XR's I've owned reasoning that with it gone heat would dissipate from the pad to caliper and fluid more efficiently however I'm rethinking my logic on this issue after experiencing brake fade again on the rear.
Refitted the wear indicator prior to the last ride but that was a three day in the Flinders Ranges and we had nothing like Billy Goats Bluff track to check for fade.

Interested to know if you have the wear indicators fitted?

Question

g'day lads,

I've put 26,000 clicks on my XR250R and want to go up a few sizes as i'm mostly on the open road nowdays and have a big 2 month solo trip planned for 2014, are there any things in particular I should be looking for when inspecting second hand BRP's?

I own a few bikes, including two old 1940's BSA's, I have a reasonable idea as to what to look look for when inspecting used bikes but I was more interested in if there were any unique BRP tell tale signs of abuse, misuse or lack of maintenance?

I'm mostly looking for something close to original or with a documented service history, big kay's on a bike don't scare me off as long as it's been serviced accordingly.

Any honest help or advice for me being a young fella would be greatly appreciated.

-nick

Nick,

Your main priority should be to get one that has not been dicked around with. Idealy a dead stock example with service history, as you mentioned. The km's advertised are rarely genuine, so look for signs that support a low km bike, wear and tear etc.

If is going to be a keeper we can help you do the mods to make it handle and be bullet proof. Don't touch anything with a dodgy sounding engine. This is the best part of these bikes & if you never have to open it up, you're likely onto a winner.

Let us know what you find.

Cheers!
In a perfect world I'd keep it and buy another, but as we all know...
