Water Temp

8 posts in this topic

I have a Acewell speedometer with tach and water temp gauge

The reading I get are way cooler than I thought I would get

What readings are you guys getting on your temp gauges?

There are times on the road mine wont even register cause it says that the water temp is below 120 degrees. Im finding that hard to believe

the only place I can see to mount the water temp pick up is the hose leading down from the top of the shifter side radiator

How do I mount the pick up in the head?

Do I have to drill and tap a hole for it?

That isnt going to happen and I dont see anyone else doing that, are they?

Remember these bikes have no thermostat, so if you are not stressing the cooling system, eg. lots of heavy throttle, they will run quite cold. I ran my WR 400 without water for about 30 miles after loosing the water pump seal, just by taking it real easy and it never got hot. I have an oil temp gage which is probably a better indicator of how hot the engine really is.

Mine runs about 150 with both rads taped off, but I have to really ride hard to get it at that temp. With the rads open it wont read the temp (below 100) outside temp was about 20 fairenhight. If I dont tape off the rads my oil will not burn off the moisture in it and turn a milky color. It has even ran out the dipstick hole when checking the level.

The vapor reads as the coolant exits the engine. My 426 runs about 160-170 but will start to go over 200 when sitting still. I set the "warning light @ 200 and the "danger" light @ 240.

So this might mean you need to try and mount the pickup on the other side down low:excuseme: I am not sure just a rational thought based on the posts in this thread.

No, it just means I'm not a very fast rider :smirk: Reading the temp as it exits the engine (the hotest point) it always best IMO.
