Most of them are going around 100,000 now with good maint,so enjoy it!

I have 67,000 on my 99 FXR2. Did have to have head gasket replaced under warranty the first year I had it but since then nothing but oil changes, runs as strong now as when I bought it. I did read somewhere that someone said lifters should be replaced every 25K miles and have always wondered if this is true. Comments?

A friend of mine has an Evo with 120,000+ miles on it.

Heard that also but I don't know anyone that has followed that recommendation. Probably written for the guy that never changes oil or cleans the screen.

Due a compression check every 10,000 miles or so. If the cylinders are within 10 % of each other just keep riding the pizz out of it.

165k on mine when traded for the 09 I have now. Still no smoke, ran great, no problems, no rebuild. The key to it was changing the oil and filter every 2500 miles and making sure to clean the lifter screen. Oil of choice ? Castrol GTX 20w50

I was told that the change to the newer "B" lifters on models that had the previous would negate this, but that there was a bulletin back in the day suggesting we change lifers at 25k.

The Evo's are a great engine, and with proper mainrenence, will last well over 100K miles. Over the years, the biggest issue is the tappet rollers. The roller bearings, or wheels on the tappets wear out in the neighbor hood of 40K miles. It will start with a slight ticking noise, and progressively get louder. Then the roller will quit rolling and skid on the cam, ruining the cam. By that time, you will hear a lot of noise, pounding and screeching as the roller skids over the cam lobe. If the issue isn't dealt with immediately, the roller bearings in the roller will fall out and work their way back into the oil pump, also ruining the oil pump. Keep your ears open for the noise, and if it starts making noise, get it diagnosed by an expert. It could save you the price of a cam and oil pump. Also, avoid the cheep Taiwaneese lifters that sell for under $100.00, they are the worst. I like S&S's the best my self.

I did my '96 BadBoy at 100,000 miles. Then, the main reason was a base
gasket leak. I did the engine Reman. Nothing wrong with this program but
I wish I had done the New Engine.

drjones...will replacement tappet rollers wear out around the same mileage?

I've got some pretty good tick / clatter comin from that side...probably time to do those.

Is that a job a fairly inexperienced wrench can do?
