oil level?!?!?

6 posts in this topic

I have a 2000 yz426f and I’m never able to get a proper reading when I check my engine oil level. The manual states that total capacity with filter change is 1.69qt's. When I fill the bike with this amount of oil and do the proper procedure for checking the oil level on the dipstick it always reads past full. I warm the bike up, kill it a put it up on my step-up stand, then remove the dipstick to wipe it clean and then re-insert it without threading it in, but when I pull it out to check the level oil is just dripping off the dipstick because it’s so full…what the crap???

It sounds as if you aren't draining all the oil from both the tank (frame) and the crankcases. If you are, just don't add so much when you refill.

I’m pretty sure I’m getting all of it out. I drain from 3 points...drain plug on down tube directly behind the front tire, then from the drain plug on the bottom of the crank case, and then finally the oil filter.

Try it with 1.6, then, and see how that works.

One of the great things about a dry sump system is that the oil level isn't as big a deal as in a wet sump. Overfilling a wet sump will make the crank splash in the oil, which will throw too much on the cylinder walls and overwhelm the rings, besides the drag it causes. A dry sump isn't overfilled to a problem point until the oil being returned from the crankcase won't all fit in the tank, in which case it results in the crankcase being too full, and the same sort of trouble I just mentioned.

At lower levels, a wet sump is much more likely to have oil slosh away from the pickup than a dry sump is to have oil move away from the feed fitting at the bottom of the tank.

try letting it sit for a few mins before you remove the dipstick... and see if that gives you a reading...

thanks for the info grayracer! I just wanted to make sure i'm not going to destroy my engine some how by putting a tad too much or too little oil in it. I'm gonna try letting it sit a couple of minutes next time before i check the oil level.
