Hi everyone, anybody who can help and share pictures and general info on this swap?
I'm currently working on a Polaris 2001 500ho swap for one of my fl350 that has been seating for a while, I'm planning on using both clutches from the Polaris to maintain all the ratios as it was intended, designed and ingeniered and to accomplish that I'm modifying the secondary clutch to fit in the oddy transmission shaft, so far I'm looking for a local machine shop that can do that for me, I already have the Engine mount from Farr a while ago, but I would appreciate any help from those that already done it and are willing to share the info.
Thanks in advance for any help
JP

51 views one respond......I guess I'll have to figure out some how......lol
Thanks Canadian oddy for responding, I promise if can successfully finish this one I won't be holding the details of my build and I would share it with anybody who may be interested on doing the same swap
Cheers

I tried to reply to your PM but my computer crashed and shut down.
When I logged back on the messages were gone and said something about pirated software ??
That don't make sense to me but what ever. My computer is clean and I update daily.
So I will reply here.

I just think that this Engine swap is very rare and that's why there is limited info on it.
Post your project so we can swap ideas and make recommendations.
I am really looking foreword to this because it is so different and rare.

Well I think I just found out my computer issue.
I was downloading a youtube video using "free youtube downloader".
Now it don't work. It has previously worked for years.

Well there's people in here that has done it before a while back but for some reason did not share info or replay to messages or emails, anyways, I would make it happen some how

Can oddy, do you think I would have better luck if I post it in projects?

Farr is the guy that did the swap in that first thread I posted.
Manny builds great stuff and he won't rip you off.
He is slow to respond though -- from what I have read here -- so you have to be patient for any replies from him. He does not come on here very often. He has not been on this site since last year (Feb 03/18). Probably best to contact him on his website if you have questions: https://farr-offroad.com/

Can oddy I did purchased the motor (( Internal Combustion Engine ? )) mount from him a while back and he only post one time about it, he never talked about it again and I check he's website, he removed the pictures of he's built and also remove the Engine mount from he's list of stuff he sales

Hummm --- oh well keep us posted as this is an interesting project. Maybe the members here can provide some help and advise.
When I first got my oddys I blew engines constantly until I could figure it out. At the time I was very frustrated and wanted to do an Engine swap just like this. Once I figured out the weaknesses of the oddy Engine I gave up on the swap idea. They run flawless now and have enough power to break your back in a crash.

Everybody was comment or worry about top speed but to be honest I not worry so much about it since I'm not near any open land to get crazy full speed, only on a frozen lake on the winter but that's pretty much it, everything else is just trails in the woods no enough for constant full throttle anyways, also I noticed that everyone who did the swap used the oddy secondary clutch witch may explain the possible lost of power so I'm trying to adapt and use the Polaris secondary clutch, I'm wondering if that would make a big difference since that was the way it was engineered to move a 696lbs and the oddy is 592lbs, no mention that if work as good as I think, it can be tune for better performance, but first I want to get it to work with stock clutches and go from there

I am almost in the same boat as you with regards to top speed for an extended run. I live and ride in the mountains so speed is very short lived or you fly off a cliff or hit some trees. Most of our top speed I bet was under ten seconds in duration and then very hard on the brakes to make a turn, dodge a rock or a washout in the road.
With respect to your comment above on clutching --- in my opinion I think the real issue is the gearbox.
The oddy ratio is 10 to 1 and I think the Polaris is 3 to 1 ?? Not sure on this though. If that is the case then the clutching will be off. This needs some investigating.

Edit: Also keep in mind that the Polaris HO is a four stroke and the oddy a two stroke. I think there is a big power difference there because of that. The Polaris would have the torque but remember we set our clutches so that they don't engage until the torque curve on the two stroke is decent. The two smoke would have the rpm. From what I read in those threads above this an easy swap and it seems to work decent for what we would do with an oddy based on where we both ride.

I just thought about this some more with regards to gearing.
We know the oddy gearbox is 10 to 1.
The Polaris I think is 3 to 1.
But we may be missing something here. The Polaris gearbox may be 3 to 1 but what is the final drive ratio ?? Remember it has a chain drive and there is a sprocket on the gearbox and a larger sprocket on the axel. So what is the real ratio ?? This needs to be known. It may be that the final ratio is the same as the oddy and if so then you are golden. Even if you are close then it is good enough. I suspect that is the case because according to those threads, the top speed is very close to the oddy. It comes in at about 50+ mph to 63 mph.

I don't know what I did but I reposted your answer twice and no what I answered.lol

Some people has said that the top speed on this swap was around 55 to 60 which is good enough for me for the type of riding I can do around here, but that is also using the oddy clutch so I'm thinking on using the Polaris secondary clutch and belt, for some reason I think this should work better and get some more power maybe? Also the oddy is 100lbs lighter, that's also a factor

Rather than build something that is not ride-able why not just install the 670 rotax, and if you want more exotic the 670 HO which produces 128hp, a manageable HP for the 350s frame and reduction case? I have the 670 HO, clocked with a RZR at 78MPH with a quarter throttle left, you will have more power that you need and a machine that is also more common.

Meegusmaster, no sure what you meant by no drive-able but if you read the previous post, I explained what I'm doing, I'm no looking for a race machine and also cost is a factor since I got the Engine and all the components for free, so that been said 50 to 60mph on the woods sounds pretty good to me.

My buddy the beer poacher owns a Polaris scrambler 500 HO and got into a huge wreck in 2014.
Myself and a couple of friends had to go out and recover the machine. I was that last person to ever drive this machine and onto a trailer.
He hit a large rock at high speed and ended up cracking some ribs and breaking his collar bone.
The machine was badly damaged and is still not repaired.
If you want I can go over to his place and find out what the final drive ratio is.

Thanks canoddy for trying to help me figure things out
Maybe you can get your friend's Engine.
Anyways, after a lot of research I found out that the clutch of the oddy would work just fine, my only gain apparently by using the Polaris clutch 91/2" vs 81/2" oddy was more low end power, so I'm just going to start putting things together this weekend and see, also I'm going to look for a deal on a aftermarket muffler and air filter

Anybody good with electrical diagrams? I'm trying to figure out the wires on my Polaris 500 swap
Please help if you can, or correct me if I'm wrong, so far I think I figured out part of it but no 100% sure on the extra black wire on the polaris CDI (Capacitor Discharge Ignition), which it going to 3 places, one been the Engine run off switch
On the oddy that would be the green so that leaves and extra wire on the polaris CDI (Capacitor Discharge Ignition), the black one,I think and please correct me if I'm wrong that this black one is the same as the brown on the Polaris CDI (Capacitor Discharge Ignition) which it would make it to go with the green one on the oddy just like the brown one?
No sure if I make sense but I also attached the pictures of both diagrams in case someone can help me out
Thanks
JP

I am a terrible electron mechanic and can't really help.
CurtisR401 and Adnoh are our two resident electron mechanics. I would send them a PM and see if they can help. Adnoh don't show up here very often anymore unfortunately.
Also I am not sure what you are asking here. You are not very clear to me so it may be confusing to those other two guys as well. I would just make it simple. Just ask where each color on the Polaris CDI (Capacitor Discharge Ignition) goes and end it there.
The picture of your CDI (Capacitor Discharge Ignition) is crap too. I can't see all the wires.

Canoddy I can't find curtis401, do you have he's info ?

I drew up a wire diagram for this swap to help another that has completed it. I will post photos for you this evening.

Mine was not a HO but it should be the same.

Have you mounted the Engine in it yet?

Here are some photos I took of mine when I went through it.
