No Idea but the guy who had it before me ran them

Snowweasel

But that wouldn't be factory. Putting triple pipes on an efi only causes problems. Unles there has been changes to the ecu, you want the factory pipe.

Exactly. Unless your ECU has been correctly remapped for triple pipes, you will burn up the motor eventually.

thank you for all the help. could i buy the system from Snowweasel and be ok

Snowweasel

Just to make sure there are no mistakes, is there any way you could contact the previous owner to ask if they remapped?

I agree with snowweasel. Polaris never had triple piped Indy 650 or RXL in a stock form. They were only in 3 - 1 single piped coming from the factory. HOWEVER most of us speed freaks never satisfy and we always looking for ways to gain more performance. There are many aftermarkets that we can get triple pipes from - SLP, HTG, PSI, Aaen, DYNOPORT and few others. WL.

RJ Gleason

To use triple pipes with the EFI, you need to either have the EPROM chip remapped or use an aftermarket controller [such as a Boondocker] so that it will not run too lean.

started to paint the suspension and painted the running boards with spray in bed liner they turned out pretty good!

How would I go about making the Efi and how much would it cost

JD8345RT

You can't make it, you have to buy it. Costs a lot more than a single pipe too.

didnt mean to say make one i ment how do i make my sled work with the triple pipes

JD8345RT

RJ said it. Get your ECU remapped or buy a new fuel controller.

what part is the ecu and how do i do that

JD8345RT

Here is an RXL stock ECU, with a chip inside for triple pipes.



A Boondocker is a waste of money for a '91 RXL. The chip for the Polaris ECU is hard to find, but you have all summer too look for one.

so i just need to find that chip? i cant take it to a polaris dealer and if it set of for the triples

polaris_indy22

and are u sure my sled is a 1991 because they guy told me it was a 1992. also what exactly am i looking for for the chip

JD8345RT

Yes the chip is what you need. Look on eBay.

Decals/color scheme are '91. Not an SKS like he told you either; your sled is the standard 121" track model.
