WR450 Eng Temp ?

Hi all

anyone happen to know what temp range a WR450 should run at

I cant find the info anywhere

Cheers

Kris

Don't know for sure about the 450, but my 426 runs at around 160 f with a significant air flow. In the tight stuff where there isn't much flow it is pretty steady at around 190-220 f. Hope this helps.

i made up a electronic temp guage and mounted it to the top of the right radiator.It runs at a bout 50 - 70 open to tight.

Thanx for the help guys

I only just fitted my trailtech vapor and seeing temps from 140 on open tracks and up to 221 in push your way thru bogs

i was a little worried but it sounds like the norm

I have seen a Jagg oil cooler for the Yamaha 400/426/450 models.

Also used oil coolers on ebay from Honda quads that look like you could make them work.

What temps are you guys setting the warning lights at? I set yellow at 200 and red at 250. In the desert last weekend and we had to keep stopping for a rookie, the max temp recorded was 224. Should I back the red light setting down?

I set mine at 212 and 240 respectively.

Thanks for the reply! What prompted you to use 240 as the high setting?
