i know it sounds bad, and it just might be but i was doing some work on my ds 650 and next to the lower spark plug on the right side of the machine, there is a hole and its goes into the engine about 2 inches. It doesnt look like something blew up but was there a screw there or something? anyone that can take a quick look at there ds tonight and see if there is a small 1/4 inch hole right next to the lower spark plug. Id start it up to see if all is well but i'm working on the carb so thats not gonna happen soon. please help

 

Just looked at all 3 of ours, and hole appears to be normal....You should be good to go...What you doin' to the carb?

 

I have the holes there also.

 

rejetting and replacing the diaphragm, which i cannot get anywhere. The good people at mikuni have zero in North America so i'm trying to purchase a used carb off ebay. Its good to hear thats normall though thanks a bunch.

 

Have you thought about contacting Ron woods for that? or maybe HPR?

 

No i didn't contact them, but everyone else that claims to have them, later say that its a special order item from mikuni and so i'm screwed.

 

The hole is a drain in case water gets in the other hole were the other plugs sit. Just FYI

 

guys correct me if I am wrong but doesn't the polaris predator use the same carb as the ds 650

Pretty much the same carb as the pred. The few things I noticed different between the 2 is the slide spring on the Pred looked a tad bit longer and coils didnt seem to be wound as tight. And there is a grey plastic retainer ring thing that clamps the diaphram on the slide on my 04 DS that is not on the Pred. The fuel line is bigger on the DS.

The diaphragm part# for the pred carb is 3131479 from Polaris and run around $31. Can order on from
here.
