I don't know what a "old berg" mask is (09?) looks like. For what it is worth... I had this on my 07 exc with a 08 KTM mask.

Coolant constantly running out overflow

OK, I searched the other threads and didn't really find an answer.

It started just today. I warmed her up, went to the end of the driveway and smelled coolant. I looked down and noticed a splash out of the overflow. Odd, I thought. I figured maybe just a burp. So I went down the road to the gate, up and around and double checked. Coolant was now streaming out of the overflow. It wasn't overheating. The fan (yes I have one) wasn't running. I could touch the rads with bare hands and hold them. I popped the rad cap off(It seemed way too easy) and lots of milky foam was at the top. Odd, I thought. I started the bike, and the coolant rose, bubbled and went up and down with RPM. Odd, I thought.

So I turned around, went home and came here.

Prognosis gentlemen? Head gasket or loose rad cap or something else?

Thanks in advance.

Edit: Oh, it still has tons of power, and no evidence of coolant in the oil.

Sounds like the head gasket to me.

The higher pressure oil is being pumped into the lower pressure coolant.

If your coolant level is going up, is your oil level going down?

Make sure it is not something simple like it is overfilled. When cold, the coolant should just cover the top of the fins and no higher. Any more than that, all the extra will overflow out. A different cap is easy to try out too.

The coolant level hasn't changed in 20 hours. This started just all of a sudden.

There is no visible evidence of oil in the coolant either.

I let her cool down and the foam disappeared. The level was below the fins, so I topped it up a bit.

I flashed her up with the cap off, when reving, the coolant just went up and down gently with the rpm.

I put the cap back on, then warmed it up practicing wheelies up and down the driveway for 15-20 min or so. No coolant coming out. I parked it, let it cool enough to take the cap off.

This time, when reving, it started out smooth, but after a minute or so, bubbles started showing up...more and more agressive as time went on.

I'm starting to suspect head gasket. But I'm trying to eliminate the simple stuff.

OH, and this time, I tightened the cap by bending the tabs a bit.

When you said "milky foam" I thought that meant something else besides coolant was in there (ie oil).

If that's not the case then I think (some small amount of) the cylinder pressure is escaping (through a break in the head gasket) into a coolant passage - over pressurizing/introducing gas (not gasoline) into the cooling system.

Yep, sorry for not being clear. By milky foam, I just meant really fine bubbles like it's been whipped by a cappucino machine.

I'm starting to think head gasket also.

OEM subframe conversion to aux fuel tank

Link to PDF of conversion provided by Åmme.

The subframe does look different than mine and that extends beyond the color (black vs grey).

Thanks to Blakduk for also sending me a copy to post.

I did not follow that description I will try to make a description with photos in PDF format tonight (can't upload photos here for the moment) and if you PM me your e-mail I will send it to all of you.

Thank you so much for putting that up! Also, thanks Amme for making the howto.

It doesn't look too bad, provided the subframe doesn't leak too bad on its own.

I love my Rekluse too - but I love the fact that I can "turn it off" too with the adjustable slave cylinder.

In reality, the adjustable slave is for setting the clutch free-play correctly (yes, apparently, even hydraulic clutches have free play) - and it allows trail-side adjustment, without the need to open up the clutch on the side of the trail...

It's sounding like a head gasket issue to me too... BUT - try this first (if you haven't already). Drain the coolant as completely as possible (checking for any obvious contamination) and then refill with *JUST* distilled water. Run the bike until warm/hot then drain again. Check for any visible contamination again. With just distilled water, anything other than water should be more visible.

It might help answer the question...

You can pump compressed air into the cylinder at TDC and see if the coolant bubbles. This will tell you 2 possible things: 1) your head gasket is bad and you are leaking compression into a coolant passage forcing coolant out of the motor...or 2)...ignore 2 because you would have oil in your coolant if it were the case and I just thought it through

I have converted to a LHRB (Left Hand Rear Brake)...so no clutch for me. However I have heard there are now ways to do this and still maintain both clutch and LHRB.

Fan Switch

I'm planning to install the radiator fan on Friday but can't find the NAPA temperature switch mentioned in this thread in stock anywhere. Are there any worthy alternatives? Has anyone used a different temperature switch?

Many, many thanks!

Just install it as is. When you do need a lower temp switch, buy it and install. I replaced my switch, in place, and lost no more than 1/2oz of coolant. It took 2 minutes.

I bought one of these 91F 2 pin switches
