Harley EVO vs Ultima

I have a 92 Ultra that I need some info concerning witch detection to go first of all this is what I'v done to the engine
Screamin eagle heads
high lift roller rockers .675
30 over cyenders KB pistons
510 S&S cam
S&S super e carb
tech ii ignition
true duels
Vance & Hines mufflers
Andrews adjustable push rods

The last ride I went on I lost all my oil through the crank vent and it puked it all over my rear tire and brakes , I lost the suction side of the pump so i need a new oil pump that's the least of my worries . There is aluminum shavings in the oil so I figure I need to rebuild it or replace the engine , What are the thoughts on the Ultima 107 engines and the longevity of life for them

I'v found my info on the site I should have looked a little before asking sorry

Rustyone, Sorry to hear of your motor woes. Lots of knowledgable folks here willing to help with any technical questions you may have - I'm just usually not one of them LOL. Welcome to Bike Talk!

Thanks Josh that is good to hear because there is a difference between the Auto engines and the Harley

What do you think

I've found a few reman Ultima 107 for 2,700 it's just the motor no carb or ignition , they have been re manufactured by Ultima and carry's a 6 month warranty If any one knows of a better deal on there motors please let me know . when I do buy the motor from whom ever then Ill be asking a lot of questions on setting it up , at the same time Ill be installing my Ultima six speed trans kit and will need some guidance there also

Re: What do you think

Seems pretty good....6 month/6000 mile warranty is nice...Good Luck

Re: What do you think

I would stay away from a remanufactured chinese motor. There's prolly a good reason it had to be "reman'd". JMO.
I've heard lots of bad things about them.
Go with S&S and you won't regret it.

Are you sure it's aluminum shavings, did you put a magnet to them?
You may just need an oil pump. It the pump blows it will most likely leave metal shavings behind in the oil.
I would drain the oil, add new filter and new oil pump. Check the compression and oil pressure and then decide if a rebuild is required. Rebuild your motor if you have to. You have a lot of good parts in it.

yes I did use a magnet and they didn't stick on it , the oil is full of shavings I bought a new pump but got to thinking that what ever is coming apart in the motor needs to be addressed and rebuilding it would cost as much as buying a reman from Ultima . I would not use the old cylinders I think that 30 over is just to much for dependability , I have 44,000 on the top end sense the rebuild on the the top end

Re: What do you think

my understanding was the Ultima was built here in the USA am I misinformed

The rebuild price is dependant upon what parts need replacing.
Did you get a quote for the rebuild?

Re: What do you think

"built" here is different from where the parts are actually made. My understanding is they are chinese made. Rev-tec is too I believe. That's why they are so cheap.

Re: What do you think

Money is an issue so is the 107 the same as in the problems , I see a lot of the 107 s being sold on the internet for 2,600 to 2,700 and this is why ive asked so many question about them . Ive gotten a lot of good miles out of my harley EVO but not being that familuer with cycle motors I'm just a little skidesh about going into it , I know auto motors inside and out but they aren't the same

No I did not what I did was sit down and figure the worst case possible and the best . Harley wants 2600 for a reman and they wont reuse my heads witch is bs , they also wont sell me the engine unless they put it in

Re: What do you think

Ultima's are good motors now...Run from Rev wreck though....

Re: What do you think

so the reman 107 s shouldn't be an issue ?

Re: What do you think

If you know auto engines inside and out...you shouldn't have a problem...seems like some GM parts and sensors are interchangeable lol....Get the service manual and parts catalog and a box or bottle of your favorite beverageand go through the books...

Re: What do you think

Who is the seller? A private Ebay seller or a reputable company?
