^^ I have to ask, what went wrong with the Evo?

 

A piston seized up. The bike rode home to Candler, NC from Montgomery, AL in the back of a U-Haul truck.

 

YUP had one do that too but closer to home ,

 

Had that happen on a brand new 73 XLCH. Picked it up and tried to drive it home. Nice easy ride on country roads. It wasn't feeling at all well, so I turned around to take it back to the store, and it seized at the next stop sign. They told me they put a new jug and piston in it, but when I tore it down that winter to change the pistons, the rear jug was .030 over.

 

I will get back to you on piston jet squirters for my EVO. ( to stop piston scuff)
The project got put on hold for a bit (too many others), but back at it.
AFAIC and most other engine people, Harley installs them in the wrong place.
Off to the side does not help much.
Porsche, diesels, and most everyone else, has them aimed so they hit the bottom, above the rod or close.
It has taken me a bit, but It finally came to me as how to get this done .
In theory anyway....LOL
A very tight squeeze.

 

Looks like its just a question of enough meat in the case. And you can buy extra meat in rod form. This is an S&S 4 inch case with squirters. They look to just be trilled into that tappet block oil galleys.

 

If you guys want pics, i will post them, good grief I don't want to start another war over this..
One can like the idea or not.

 

My name is Maximus Decimus Meridius

My Name is Jeff

 

Thanx!!!
Where did you find that? ^^^^
I am going in from the front and from the rear ,,,on a stock case. I hope.
Remains to be seen..
-------------------
Parking lot?
My old iron head popped the finger in the transmission on my old iron head 500 miles from home.
No shifting for me!
In the HOT sun in Spokane or Eastern - Hot WA somewhere.
I was with several other riders.
They all thought I was finished.
They went and had beers whilst I went to the auto parts store (in parking lot) bought a drain pan,
And some other thing and pulled the trans out right there!
Got the shift finger back into place and WEEeeeeeee hour or so latter was ready for a sunstroke but done!

 

Lol You brought it up.

 

I do not think there is a best engine, every one, from shovels forward have their own set of issues... evo type as well as TC type engines I like.. they have problems, and are well known.

 

not so much about performance and reliability but my favorite big twins are the old ones you
could back down the idle and get a nice potato-potato lope. think it was still an option with
the evo but went away after that.
i've always wanted to do it to my TC, won't happen because i've read it's bad for the compensator
and oil flow.

 

Depends on what year you have 5 speed TC have a good comp and at low idle I bet my pump is pushing more oil than the small external gear pump

 

Very nice oil lines

 

do you have a tach on your bike Hoges? what RPM does your engine idle at?

 

I don’t.

 

There are gerotor pumps available for the Evo and maybe the shovel That put out way more volume...
I just bought a new one a couple months ago.

 

Thermodyne,, is that rad8cal pre 1971 sportsters one of yours?
As I got older and I think wiser, I went with a large but not easily fatal dose of power, (engine),, blended with streetability and civility, also in the mix rel8ability and upgrades to all systems on the bikes.. especially major brake improvements. Stopping is more important than accelerating

 

Bloody Hell sorry for double posting ^^^^

 

Terry is it not a 750 XR ? Therm posted.

 

That's a great idea! ( from return on oil cooler)

 

Yes Mate trying to keep head and piston temp down to stop pining . I do have adjustable timing. Trying to run a reliable performance engine. So far so good 😊

 

My only question is, being on the scavenger side, the oil will take the path of least resistance .
So How did you make it go to smaller orifices>?
I am thinking of robbing it off the oil pressure switch, but have not got that far.
Thanx

 

I’m running a 3/8” I’d hose . When I disconnect at oil tank when full flush oil change it still has the same flow or more than stock bikes I service. I have removed sump plug after a hard run and measured 3 oz of oil. So no issues with scavenging side.

 

Most of the time,it’s the one you own,when being asked.

 

^^ maybe for some.
I certainly miss the simplicity and romance, of my old iron head Sportster.
As I have said elsewhere , i rode it coast to coast and back after vietnam.
If it had a belt drive, it would have been a perfect bike!

 

Twin cams are great, 100k on 09 classic

 

I like the TC 96" I have right now. My wife had a Sportster for a couple years with the evo engine and it never gave me any problems. I rode it more than she did. It was a fun bike to ride. She sold it to my daughter in law. My 2010 Electra Glide had the 103" TC, no problems with it. I just do the routine maintenance and don't ride (too) hard so that probably helps.

Back in 2020 my son bought a new Low Rider with the 107" M8. Wow! Lots of power and fun to ride. That's all I can say about the M8's.

 

I will add to the display of thoughts and conspericies here..
If one is at the mercy of a "shop" as to what is better and what they deem worse, as needing fixed, then we have that to lean on, their opinion.
Not necessarily correct.
Maybe a way to look at this is, if you had to be broken down on the moon, so to speak, which would you rather have to fix?
A mystery of electronic parts, pumps, computers, and numerous features that may have caused the breakdown?
Or a simple machine with points?
That's how I judge which is better.
Do I need someone to help me, and am I at their mercy?
Or can I do whatever is needed, besides the road?
That's the scorecard I use.

 

The best Big Twin is the one you have now.

 

I think the most dependable motor Harley ever made was the motor that saved them. The EVO.
