Need Help Identifying two motors
 
I just picked up three older Polaris sleds, and have two extra motors that I picked up as well. The guy was all Polaris, so I am pretty sure that they are both Polaris free air motors. One is a triple, with three larger carbs--probably 38+mm, and it has individual coils mounted below the carbs, and what looks to be a cdi box. It has a motor tag, but only says 1614. The second is a smaller twin cylinder, which is also air cooled, and it says 9300 on the tag.

They are air cooled for sure, but I do not know what cc, or year.

Any Polaris gurus out there that may be able to help me?

Thanks,

Monza.

There wouldn't happen to be a FUJI HEAVY INDUSTRIES tag on them anywhere? If not, the engine model # is stamped on the cases...somewhere. Usually by the recoil.

If it's a Poo triple free air it's a 500 from the early 70's... or maybe a 650? Unless it's the 634 Hirth f/a? Got some pictures?

Look on the base of the cylinders (pto side) and you will see some numbers cast into them. This will tell you the size and other info.

your not giving us much to guess on? not so many triples, but a lot of twins, some HOT some just another moter!

If you have a triple free air Polaris motor I want it, please.

Polaris Motor Identification
 
3 Attachment(s)
I looked at it a bit more closely, and found an EC 65 on the case by the recoil, and an E 65 on the cylinders. Here are a few pics.........

Looks like it might be a F/A from a Centurion.
It is a 650.

Monza406 11-21-2010 02:20 PM

Any idea what vintage it may be?

blue avenger 11-21-2010 02:36 PM

free air 650? is what I'm thinking. Tag below the PTO exhaust port blank?

Monza406 11-21-2010 02:55 PM

The tag is blank, except for 1614.

OCR 11-21-2010 03:13 PM

What is the whole casting #? (EC65***)

Monza406 11-21-2010 03:25 PM

That is all I could see, but maybe there is another larger number somewhere else on the case.

Air Cooled Twin Identification
 
I took a look at the twin cylinder, and there is only a blank tag, with 9300 on it. The cylinders have EC34PF-02 on the base, so maybe a 340? Again, not sure what year.

Any help would be great.

Thanks,

No F/A centurions, only 500 cc triple liquids.

The next 2 digits for the triple would be PT as in EC65PT. That's a free air 650 triple most likely. They may have used the 650 bottom end and put 500 f/a cylinders on it. Early to mid 70's I'd guess but they didn't have CDI's then? Might be a frankenstein motor? Take a picture of the front and back square on as in the cylinders lined up like this 000 so I can see alignment of the cylinders. I think this is a 2+1 engine.

The twin is a 340 fan cooled engine. The PF gives it away as being fan cooled. The T's were free airs and the L's are liquids.

Where did you get these engines? PM sent by the way.

They are junk, you better send them to me.:poosy:
