Multiple things are falling into place. 2013 are holding up and oddly enough someone has suggested that this will be the case based on measurements and analysis. Tough to argue with facts..way tough and I highly doubt that this individual took a file or some other means of removing to match his hypothesis.
Fix Kits!

OK Guys... I think this it is time to really get some HARD facts!!Please remember I am doing this to HELP you guys to NOT make a bad decision .
I must admit I am 100% blown away at the response of the 2mm offset claim and the "proof" coming in the form of a measurement that has NOTHING to do with the crank centerline! All from a crank "expert"
In any case it is time to get some REAL FACTS on the table here..
1)There is NO crank offset from 2011 to 2013... The crank is located in the same position with respect to the cylinder bore.
Yes, Proof of this exists in the form of pictures of a 2013 upper case half mounted on a 2012 lower half. This clearly shows the crank location to be in the exact same location. There was no re-tooling or off-setting the crank or the cylinder...Sorry guys.. but it is the truth.
2)The 2013 DOES have a different crank than the 2012. It is manufactured by FUJI vs. MAPE. This IS a better crank but the design is the same...just Japanese parts vs Chinese/Italian
3)The Rod/Ratio of this Polaris engine is WELL within design specs and is , in fact, better than the CAT or the DOO in this design...The idea that the rod/ratio falls short is simply a "sales" technique to get you guys to purchase a product/service that is not needed.
Call up ANY reputable crank house and ask them if the rod ratio is low.. You will find the answer to be a solid "NO, the Rod Ratio is fine"
I will stop here because I do not really want to get any more involved..I was hoping to just get Dan to answer the questions that were asked of him. He would not..
I would strongly advise anybody who is considering altering ANY part of their engine to ASK the question: "WHY DOES MY ENGINE NEED THIS ALTERATION"?
People, this is ONE question you should ask EVERY supplier (including me) on EVERY product that you are considering dropping you hard earned case on.. Again, ask the questions!
Again, I am posting this info to HELP you guys benefit from knowledge and facts vs. lies and conjecture...
I am sure many of you will see this informational post as something that it is not.. but I will re-state, I am only posting this information to help you guys with your sled decisions...
There is a big difference between helping out an engine with better components vs. altering an engine design spec because it "NEEDS" it.
I will not get into what altering a rod length does in terms of engine operation but a change in this area greatly effects MANY aspects of the engine's function... Sometimes for the better and sometimes not..
Oh, no personal attacks or name calling has been used in any of my posts. You can ALWAYS get the facts out there wihtout resulting to personal attacks.. The facts stand on their own merit... and always will.

The 2013 cylinder is in the exact same position as the 2011-12 cylinder.. So, you are correct, the cylinder mounting location is key, and it is the same..

Kelsey, are you that hard up? I asked you a very simple question, how many 900s do you have going? with how many miles? A lot of people like your drop in kit but there isn't no need for you to come on here with your derogatory comments. Some people like your stuff and other people want the best. You just started in the Polaris seen with the pro. Indy Dan motors speak for themselves, ALL of them. Let your kits do the talking, not your fingers on the keyboard.

WOW!! More mis-information... We have been doing Polaris since 1994...
As for the 900, we had the very 1st 900 Billet head for the 900 and it worked well.. As for the 900 engine... We saw too many design problems and a chassis that was not optimum for mountain riding.. We figured the engine would be very short lived and out of production very quickly...So, with that information in mind, we decided to not concentrate on that engine or platform and it was discontinued after 2 years in production...So, we feel we made the right decision.
We built countless 800 engines and did all of Carl's Cycle's 910 heads for them for a few years... So Polaris has been a large part of our business for almost 2 decades//
Hope this clears the mis-information up for you??

Guys, give it a rest... this is getting to be a bit much!
Jeepin270,
You are such a child, I gave you a negative comment because you talk out of your a$$! You have no facts to what you say, uh uh but Indy Dan! Holy crap dude. I am pretty sure Indy Dan can handle his own fights, he doesn't need his cheerleader in the corner waving her Pom poms.
I have quite enjoyed this thread there is a lot of valuable information. As to who is correct in my opinion still to be determined. But have good arguments and I am sure both Kelsey kit and Indy Dans long rod kits are both improvements to the motor.
What did you do go to every post I made and give a negative even ones where all I did was tell some one thanks for the help.

That is a pretty chicken **** thing to do.
ok.. I guess I am the only one who speaks highly of my engine builder. hows your 910 holding up
The video
Holy cow !! Things are wild on here !! Ok thanks for the help from Steve a crafty Canadian I got the video converted so it will up load.
Please understand, I was going extremely fast in this video and I threw this pile of parts on a table and told Cade to follow me with my iPhone.
Now I am not going to over tip my hand do to the fact that Kelsey needs to try and figure some of this stuff out on his own before he claims to be gods gift to the Polaris motor.
There is also a lot of examples and data I left out about the differences in short rods & longer rods and the plus and minus of cast or forged pistons. And why one clearance is good for one motor and not another. And why sometimes you have to Taylor to a certain person and where he rides or what he does.
Or if he has a turbo or runs nitrous and so on.
And please cut me alittle slack on the video I was racing to keep it short but I hope most everyone gets the idea of just a few factors that go into these motors.
And I used the most basic example I could think of in the short time I had to show the off set.
Here's a link to the video.
https://vimeo.com/62214565
The off set is in the top half of the case and nothing can be learned by anyone by putting a 2013 upper on a 2012 lower. All the off set is in the upper case half above the bearing area.

My PAR 910 is running excellent, thanks for asking. Ridding 2-3 times a week and hasn't skipped a beat.
I think everyone on here speaks highly of "their" builder, we all want the best product that our money can get us. But I think the rest of us try to learn as much as possible, especially if its something we have no clue about, before we open our mouths.
Why does Kelsey owe you any information at all, " are you hard up, I asked you about the 900), who gives a rats a$$ about a 900 on this thread. I don't think that's the topic at all.

Indy Dan,
Honest question, On your video how do we know that the length of the intake isn't just a different length on the 13 motor. That's all it looks like you are measuring. I don't see how that measures anything with the crank or any offset there might be.
Maybe I just don't know what I am looking for. Can you please explain?
Thank you for taking the time to make the video.
