Expansion tank exploaded
So, a group of us were out hammering thru the riverbeds and single track...totally abusing the bike.
Stopped for a rest and and "kaboom", scared the hell out of everyone! Sounded like a Glock 45 The whole bottom of the tank blew out. Anyway, I just eliminated it and ran a straight connector hose. Anyone else running wthout the tank? Just curious. |

It happens. That tank is a bad idea, as its prone to damage from abrasion and subsequent failure. I remove it before riding the bike, and leave an air gap as was mentioned. A KTM 1.4 bar cap works fine. Moto9, for the real slow hell rides you do, you can add a couple of the inline alloy finned coolers, they work great. I have those and an LTR impeller and never loose a drop in any conditions, even grunting around with the kids. EVANS NPG R coolant is also an option.

I'm running my 2010 GG 300 without one. Took it off when we removed the light for a numberplate; no problems to date.

I boil the piss out of my bike regularly, I always know it its coming cause the KTM's are puking way before mine. I need to try the expensive coolants. But water is just so cheap and always available, plus I don't start gagging when I inhale plain steam.

Paul,
Likely from elevation. Run an LTR or Checkmate impeller and the NPG R. It will not boil. If it made my Cannondale ridable in the gnarly stuff a GG is no problem. Engine Ice may be slightly better than basic water/antifreeze, plain water boils easiest. |

That was a must on my 2006 450EXC or it would spit out anything over the fins when the going was slow. RLR made a nice little overflow/recovery bottle that allowed me to run the extra coolant.

I have always taken the tank out and replaced it with a connector hose. Never ran the tanks at all as it is a bad idea. I have no overheating problems except that I sometimes have to empty my Camelbak into my friends' KTM 4Ts radiators.

I couldn't ride a 450F around here without EVANS coolant.
