92 sp efi

My indy 500 so efi has a bog when you crack the throttle wide open from an idle,when revved up its great. I know a lot of guys convert them to carbs but I don't want to do that.

Are you shure its not a beldt issue. Is your beldt deflection set right?

 

[Vectorman05]

Yes, it does it with The belt off. I'm thinking the tps might out of range,but not far enough to trigger a code.

 

[MrSled]

Drain tank and add new fuel?? New plugs?? Fuel filter?? did you do a compression check on it to be sure that its good?

 

[Vectorman05]

The tank was drained after last year,new fuel filter at the end of last year(riding year)rebuilt motor,crankshaft to spark plugs.

Try taking the injectors out and hooking them up to a 9volt battery so they operate and spray brake cleaner on to clean them out.

 

[Vectorman05]

I'll try that, are there any long time polaris mechanics that have access to or know where to find the polaris select monitor? I have a program for the pc that is the same thing but still have to get a cable to hook up.

Has it always bogged or did it start doing it recently? I've had 2 500efi's and they both bogged off idle a bit. I installed a higher engagement spring in the primary and it solved the bogging issue on both of them.

 

[Vectorman05]

It's just been since I rebuilt it, clutches included,I'll check what spring is in the primary,polaris springs are color coded right?

 

[Pro116]

Yes the springs are color coded.

 

[Vectorman05]

Thanks,sunday I'll take a look at what's in it,I have a couple extra clutches,I'll see what color springs I have.

 

[Vectorman05]

Ok,I had time after work to look at the spring,the one in is blue and I have a gold one.

 

[Vectorman05]

Found this this morning,I'll be switching springs on Sunday and see if that helps.

 

[MrSled]

I should start adding some of this into a quick find FAQ list.

 

[Pro116]

Actually that's one thing I had on.my list for you was all the polaris primary spring specs.

 

[Vectorman05]

I haven't changed the spring yet,will do it this wknd while I'm playing with the select monitor

 

[09nytro]

If u remember right ( it's been along time ) but there is a screw in the Cdi /EFI box on top of air box and its call MR screw that you can lead/ rich in the EFI system and you can read it with the select monitor ...there is little black rubber plugs in the side of the box , pull them out and you will see the screws .....

 

[Vectorman05]

Yep,that is for idle to I think 3000 rpm after that it has no effect. I will be getting back to working on the sleds pretty quick,have to finish getting the lawn mowers going.

 

[northstarrick]

just for your info. the older Subaru cars used the exact select monitor. you just need to use the Polaris program for your sled. a lot of these aren't used any more. you maybe able to purchase one from a dealer that's put it in storage?

 

[Vectorman05]

Yep,all it needs is the Subaru cartridge. The case actually says Subaru select monitor
