This is fairly easy on the Evo engines.

Remove top of rocker box cover.
Ease up old valve (not a good time for gorilla tactics here), being careful not to pull valve off of stem, leaving stem in the hole.
A little spritz of WD-40 down the stem might help.

Position new valve stem into hole, push down on center of valve until stem pops into hole.
If difficult, a dab of oil might help.
After insertion, GENTLY pull up on edges of valve to make sure stem stays in hole.

Replace rocker box top cover, repeat for other rocker box.

Go for a ride!

How do u replace umbrella valve in rocker box cover

Hi Nathan, no pull the old one out and lube the new one with oil then use a pair of needle nose or duck bill pliers to pull the rubber pointed end through the hole, trust me it will stretch skinny. Get back to me if you have any more questions. Do you have a service manual? For $6.50 you can download one at the website below:
Good luck

2002 fatboy with oil in the air filter

Hi Anonymous, oil leaking from your air cleaner is caused by oil carryover from the engine. For what ever reason the breather system is not seperating enough oil mist and air from the piston downstroke. There are cheap and quick easy fixes and there are more exspensive ones. Start by trying the following:
1. Run your oil level half way between the add and full mark when hot.
2. Run oil breather lines from head into a TEE fitting below carb/induction module then a single line into a mini filter under frame.
3. Purchase Arlen Ness Super Sucker.
4. Replace umbrella valves and realign oil pump
5. Upgrade oil pump and cam plate
Good luck

Oil blow by comeing out of carb at higher rpm ,on my 2001 heritage

If the crankcase pressure is too high due blowby on the piston rings, you may in for a upper end refreshing. Or, it simply could be the "umbrella valves" in the rocker box covers. You can remove the four bolts that hold the rocker covers on and replace the umbrella valve in the center section. That may cure your problem.

Good Luck

Oil leak

Welcome to harley ownership, been through this often on my bikes. The air that is displaced in the crankcase during operation builds up pressure and travels through the motor out to your air cleaner. Based on the age of the bike (no disrespect whatsoever), the umbrella seals more than likely could use replacing. What happens is the displaced air is really a mist of oil and air and as this travels up through the engine its last stop is the umbrella seals, which look like a very small umbrella with a short shaft. The bad news is that unless you want dig into the top end of your motor you are probably going to more comfortable having your shop replace these for you. If you decide to do it yourself repost and we will go from there. Also there are some after market parts that work pretty well too to help most are around $200. Hope this helps.

There is oil coming into the air breather on a harley 883. can't seem to locate the problem

This is normal, the sportsters vents oil out of the air breather. You can lesson the amount of oil by running the oil a little low, I run mine with the oil mid way between the lines on the dip stick.
