how hot is to hot?

15 posts in this topic

With all this talk about over heating how hot is to hot for the bikes? When should I start getting worried, I just installed a Trail Tech Vapor on my wr426 so I can tell the temp but not sure on what is to hot? Thanks In advance

If you bike is box-stock, it comes excessively lean from the factory. This makes the bike run hot. Re-jetting cures all but most difficult overheating issues.

If you been riding four strokes a while you will get used to the feel of more heat from the engine through your mx pants.(not like 2 stroke).

That said if you do alot of technical sections one day and its very hot out you will even feel it get hotter through your pants. Sometimes even experience a bit of "burning smell".To me that was my warning,switch off to cool down or get out of the riverbed/rocky section for more airflow!!:thumbsup:

When the water shoots out, than it's time to speed up or to kill it

Stupid question, I'm sure, but where does it shoot from when it's too hot?

Coolant first goes into the coolant recovery bottle. Good idea to locate this item. If it overheats so much that the bottle is filled, a hose runs from here down to the ground behind the carb with the carb vent lines.

If you search Hardrock RMEC race, colorado 2009. a trials like rock section had all kinds of slipping of clutch and cussing of traction/gravity etc.

i had my 06 WR boiling gas and the tank swelled up as i had a one way vent on the tank.

i took that off and put on a regular uncorked vent hose.

the tank swelled up so much it popped off its grommets. its an IMS oversize tank btw

And this is the question then; the previous owner has done a bunch of weird stuff to this thing, the overflow bottle on mine has the line leading in, but no other leading out...

I set the early warning light at 200, and the red warning at 225. Mine usually pukes some coolant around 230. I like having the Vapor, because when the yellow light comes on at 200, I can usually get some airflow, and get it cooled down before it overheats.
