Hey all,
I have a 2007 WR 450 thats pretty much stock except i disconnected the grey wire and shortened the throttle screw. I have only been riding for almost a year now so im still learning a lot about maintainence and appreciate all the help here.

This past weekend i went riding in the mountains at about 5000 ft. All day the bike ran really good until I went on a particular trail that was technical and slow due to the trees and really deep rutts. The last half of the trail I was pretty much walking the bike while it was still running and thats when I could here it boiling. It then leaked a lot of fluid and I am just curious about was exactly i need to do now. Im guessing the fluid was from the radiator and do I need to flush it now? Should I replace it with "engine ice?" Also should i rejet because I will prob only hit that elevation a couple times a year.:thumbsup:

Thanks in advance!

Bob

My WR boils over regularly as I tend to ride tight and technical, pack & carry stuff like you described... it boiled over into your overflow bottle until that got full and then started coming out the overflow tube that runs out at the bottom of the bike.

I use engine ice and while it's a better coolant than stock, it will still boil over.

With the bike cold, fill the radiator and then replenish the coolant overflow to the line.

If you want to switch to engine ice, just drain everything and re-fill with engine ice:thumbsup:

Ok so if I want to replace with engine ice I need to drain whats in the radiator, is there some sort of drain plug under the rad? And after I fill the radiator back up with the new engine ice, bike cold of course, i need to fill the coolant overflow to the line which is located on the rear fender right? and what should i fill the coolant overflow with as far as brands go? Thanks a bunch this helps a lot!

If your using engine ice then put that in the overflow bottle as well. The new generation of the Alum. framed WR's have a smaller overflow than the earlier ones and it doesn't take much to blow coolant out onto the ground. The overflow should still allow the rads to refill themselves after it cools down and draws the coolant from the overflow bottle back in. On the older WR's I never had to refill the overflow after heating the bike, but on this one you need to keep an eye on the level in there. WR Dave.

There may be a cleaner or neater method but I just place a large drain pan under the front of the bike and pull the lower hoses, open the cap to vent... yeah it's messy:bonk:

An old-wise man once suggested (well, Agent Smith :thumbsup: )

1) drain original coolant
2) flush with distilled water
3) flush with 50/50 distilled water and white vinegar
4) flush with distilled water
5) fill with engine-ice
6) :worthy:

If you are putting in engine-ice, all of the old glycol must be completely rinsed out.

You don't need to pull all the hoses, just the drain screw on the water pump.

You can't miss it.

Look for the copper washer.

I have excused your ignorance because of your age THIS TIME ONLY.

Don't forget to blow out the line to the puke bottle.

You can give the old anti-freeze to the neighborhood cats.

Very.

You can't find the drain plug on a bike you've owned for a year.

But you had enough time to put graphics on that would embarass a mexican pimp.

Just messing with the kid.

At least he's trying to fix the thing himself.

Most kids would just scream "Daddy buy me a new one, this one's broken".

engine ice will not solve the problem. The JD jetting kit worked for me. You have a jetting problem. Once you get it dialed in you can change jets, needles in minutes without removing the carb from the bike.
