not to be a pain, but what parts do I need there? I just want to get it right. Thanks in advance for your help

The long hose going across the front of the engine that connects the WP to the right side radiator. The short hose on the left that connects the left side radiator to the top of the cylinder head.
Use silicone heater hose. It makes the bend easy in the front. Takes all of 10 minutes to retrofit, fill and bleed the air out of the cooling system.
so by doing that we just get rid of the thermastat alltogether right? Hope that helps, because I have been overheating allot, its not even hot outside at all

Sethro,
Make sure you use the bleed screw on the head when refilling the radiator. If you have not been doing this I can guaranty overheating. Also make sure to leave 10-15mm of air space for expansion in the top of the radiator.
You did install the factory fan kit right?

don't have the fan kit, but I did bleed the motor with engine not running, should it be running??? And yes I have the air space right, thanks for the heads up as I am new to Hussy's

yea I was afraid that I would, I am going to hook mine up on a SPST relay, only works with engine running, wish I could find 1 no one needs anymore

To add to the others, I too had a chronic overheating problem. Per BOSS, I did the FC-style routing, even used his cool blue hose. I run a couple of ounces of Water Wetter with a 30% antifreeze, 70% water.[/quote]
Have you folks tried engine ice, motorcycle specific coolant? The guy at the local KTM shop said it works great, and KTM's tend to overheat more easily due to the impeller that moves the water turns at 1/2 speed on a KTM vs full speed on a Berg.

Engine Ice is Propylene Glycol based, and it does have a higher boiling temperature than regular antifreeze.
However, it does not transfer heat as well as regular antifreeze, or water. So, you will have lower temperatures at the radiator, but higher temperatures at the cylinder. It will still boil over too. I tried it in my Husaberg and it just did not work. It just boils over at an even hotter temperature, which created bigger problems.
As far as KTM's overheating worse than the Husabergs, I can tell you from direct experience that is not the case. The KTM has a bigger impeller than the Husaberg, and flows just fine. I can ride my KTM in tight and technical spots without problems, and in the same places my Husaberg boils.
For a Husaberg, the best thing is to run as much water with as little regular (ethyl glycol) antifreeze needed for freeze protection, along with Water Wetter. It doesn't matter if the antifreeze is motorcycle specific or not, as long as it does not have any silicates.
At Moab, BOSS told me part of the problem with the old-style tanks ('05 and down) is that they limit air flow through the radiator. This was fixed with the '06 and up tank. When I can, I am going to fit the new style tank and shrouds to see if it helps.
I met a guy whom had overheating problems on his KTM 250sx with slow canyon riding. That is interesting the KTM has a slower turning , but larger impeller, and engine ice makes the radiator cooler but cyllinder hotter. A lot of good that does !!

The EXC's are nice bikes, I was looking at a 525exc prior to getting my Berg, but the ones I checked out were cost prohibitive. The bikes with the heat issues. were 250 sx 4 - strokes, that ran hot, and also were almost impossible to start once they got a little warm. So they sold them and went with 450xcw's , which don't have the hard start issues.
I've never had a problem with overheating on my 98 501. Includes gully bashing on 40 deg days in first gear. Closest it comes is idling on the start line. Pre 01 Bergs have the cam mounted pump that KTM cloned, and Sherco and Vertamati and VOR for that matter.. Dunno why they needed to change for the new motor as it seems complexity is up, as is hose length, and the seals are no better.

Hello.
I am about to install PC fans on my bike. Are there som pictures in the gallery showing how to install fans?
