Title: Mid 90s Evos - anything special to watch for?
Post by: Finn on July 11, 2019, 05:44:06 AM
Soo, after 8 months without a Harley in the garage I'm heading tomorrow to check on a mid 90s FXSTS.

Are there any bigger issues with these mid 90s Evos to watch for or are they as good others? This one has about 37k miles on the clock but that is about all that I know of it at the moment.

leaking base gaskets, rocker box gaskets, primary gaskets, and with anything that old, intake mani gaskets and wiring.

What year bike? '96 was a changeover year to better, waterproof upper controls.

So, pretty much standard stuff fairly easy to take care of.  :beer:

Most likely a -97 but I can verify that after I see the VIN.

Pretty much, there'll likely be a long list of little things that pop up.

It's also likely to have been modified a bit by someone in the last 20+ years. So if they happen to know what was changed, be sure to double check the quality of the work. My '92 had some dude get too happy with dikes and a roll of black wire. Everything was run with black.

Thanks, guys. Bike has been sitting for the past 18 months so let's see if it runs and how well - old gas need to be replaced etc.

Gaskets are nothing . Evo's are pretty much bullet proof and a lot less maintenance and cost to fix than a twin cam .

my  '95 evo has been fairly bullet proof.. at almost 160k it is a dead nuts reliable bike. I have replaced some of wear items over the years, cam & lifters, rotor& Stator a couple times.. took the top end off at 110k and everything was within tolerance, re-ringed it, just because it was apart, had the heads checked, put in valves and guides, i did replace the the studs and head bolts....as i had a small base gasket leak for years. I replaced the spring plate in the clutch pack(still original clutch plates and drive plates.
   The best bike i have ever owned, i am keeping and eye out for a 90's FXLR, I am an Evo guy all the way, i have a twin cam, love it... if i could only have one bike, it would be a mid 90's evo

Springers tear up steering head bearings and races frequently. Check for flat spots, or tight spots when moving the handle bars right and left. Also looseness when pointed straight ahead.

Early 94 back all have the messed up narrow rear sprocket that will come loose and eat the splines.

A left side trans leak is a giveaway on these.

Sometimes you can see if the sprocket has a single lock screw (or none because it has sheared off) that is the early narrow hub sprocket.

If it has the 2 bolt locking tab it is the updated style that won't fall off.

It turned out to be a -97. And here it is at home.  :smile:

I agree. My '90 EVO had that problem.

Thanks, Hoss.  :beer:

I wasn't sure and I had to see it first.

Was an interesting trip home: front tyre seemed low and I stopped to put some air in it but the rear one looked OK. Bike was a bit of a handful in roundabouts and intersections. At home I noticed the rear was at about 12 psi. It being a Metzeler Marathon it kept it's shape nevertheless. One should not assume...  :embarrassed: Marathon is from year 2000 so it is time for new tyres.

Bought a pair of Hiflo filters and a some Valvoline VR1 20W50 - old oil was black but I have seen worse. Need to change the plugs still so off to the shop now.

Them Screamin' Eagle slip-ons are a bit too loud but they will have to do for now.

my 96's base gaskets started to weep after about 103,000 miles, my cam, cam bearing were replaced due to a tweeker of a wrench I had working on the motor before I had time to.
if a Springer, the neck bearing and rockers 'should' be replaced. 
added later  :emoGroan:
:doh: finally seen the pix, nice lookin Springer - enjoy

Post by: rageglide on July 12, 2019, 07:08:17 PM
Nice find.   Always liked the FXSTS's.  Badboy or standard models.

Get the proper grease for the neck bearings, invest in a neck bearing installer and remover tool, then plan on replacing the bearings every 10k or so.  Like Larry said the springer is hard on neck bearings, first sign is notchy self centering behavior.

My last two machines were FX springers, 94 and 95 which is a Badboy. I love them,the springers aren't weak.I changed the bearings on the 94 after 40k but they really didn't need it. I like to play with them so I changed out the cam bearing and added an EV27 to the 94 and the same with the 95 but put a EV46 cam in it and good Cometec gaskets. The 95 I bought 3 yrs ago and it only had 2300 miles on it so it sat and was hardly used but there were no issues and I've had non except for my tinkering and I do that in the winter. Enjoy your bike.

Thank you, guys, for kind words and advises. I will "try" not to let it get out of hand so first tires and normal maintenance including brakes - that should do it for a while.

very cool bike...I'd like to have a springer, but I'd want to add some rake to the front. I like the 96+ bikes for the better controls an connectors an no speedo cable. enjoy

I believe '97 (and '98) were 2 years that HD went to the tight clearance rod bearings (why - no one knows for certain - oil control?).  with the jugs off, pistons removed, you can position a rod so it isn't resting on the spigot hole and it will STAY where you position it!  Most rebuilders say that it isn't a good idea to get too carried away with hot rodding these engines without opening up the rod clearances a bit.  Just some information to keep in mind.  Nice bike though.

Doesn't that clearance open up when the motor is hot?

I don't think it was intended or on all engines.  Most 98's were tight and it became known as a 98 issue.  I have 2 and they both "were" tight as described.  I was told by a couple of techs and a dealer friend that the MOCO had a goodwill campaign for a few years after warranty to fix failures but mine were noticed too late.  To be clear, mine did not fail but were noticed when freshening the engine and the barrels were removed.  I fixed mine and added the later model crank pins with better oil galleries etc..

No tuning yet, just a couple of heat cycles.
EV13, about 9.0:1, mild cleaning of the heads, Dyna 2000i and Supermeg 2-1.

Had a 92 flhtc and on a long trip pa. to colorado kept getting this oil leak. Turned out it was the engine case was seeping oil, from what i was told the casting was pouris when the cases were made. Not sure how many were like that.

Clutch and brake levers are some cheap chrome junk and loose. Found the original aluminum levers in the box but brake lever is bent so need new one/ones.

Kury Silhouette levers too blingy or just about right?  :teeth:

The fact that the brake lever is bent means the bike might have fallen over on the right side at some time, an all to common situation. The fact that it only bent and did not break is a testament to the toughness of the stock levers. Personally I'd look for a stock lever, either new (~$50) or on eBay. Many dudes replace the stock levers for the froo-froo chromo parts and sell the stockers for cheap. Part number is 45016-96.

I don't understand why folks spend the bucks for a dyno session and only focus on peak HP.

Horse Power is a mathematical expression embraced by marketeers who want to impress FARMERS!

We'll, I'm spending my Euros for tomorrow's dyno session to get the bike jetted, ignition adjusted/checked and Supermeg dialed in. I'm mostly interested in maximising the area under curve, we'll see.  :pop:

Ask for the run files when they are done (e.g. bring a usb stick or have them emailed to you) - it makes it easier to create and post charts.

Here is a link to the result of the tuning session a few years back of my 1994 FLHR w/ Supermeg, incl. testing w/ open and closed endcap and various discs - 1994, 80", FLHR, V-Thunder 3030, Supertrapp Supermeg (http://harleytechtalk.com/htt/index.php/topic,111258.0.html)

It was a fun day.  :smile:

This is the only graph I  have at the moment and that has torque in Nm and DIN values.

SAE figures I believe are around 70 hp and 83 lb-ft.

It runs very, very well but in the dyno it appears to have a stubborn rich area from around 2000 rpm to 4000. From 4000 onwards AFR is good. Rich middle starts just when you open the throttle, sort of like accelerator pump would pump too much but everything seems to be OK there.

Tried some combos with HD needle and jets but it was even worse with those - not so many different needles in stock. With Dynojet kit stuff it was better but with Dynojet spring it got worse.

For the moment we ended with Dynojet needle with circlip in 4th groove from the top and 160 main jet. Slow jet was 45, IIRC. Supermeg has closed end cap (open not in stock right now) and all 20 discs.

Probably would run very well as it is on the road but we will look at this again when the season starts.
