Fixes for the Hawkeye
1. Tires ---i took those little 22 inchers off and put 25 inch goodyear rawhides on
(this took care of the small 4 wheeler--- i Made a mistake attitude that i got at first)
2.Broke it in harder than normal
3. I knew enough to FIx the Jetting on my own (dealership will give you a blank stare)
( Rich Condition of the carb (stalling and popping on an incline) was fixed by opening the area up on the airbox where the snorkel attaches to the Lid (we call it Portmatching in my old Porting and polishing days if you will look at the end of the snorkel there is a dimple sticking out inside it--remove this dimple to--remember anything that slows the air down or causes turbelence will affect it-Smooth airflow is the key to good intake-I used a tape measure to make sure all the air box Intake holes are matched in total inches. 1st hole 2 inches total, 2 hole 2 inches total, and 3rd hole 2 inches total and made sure there wasnt any interuption in air flow. (Little Motors are touchy about little changes you may not think a little Bit of this and that would affect it but it does.
4.Needle clip Position (moved the Clip up to 3rd clip which leaned it Out If i want low end power then i moved the clip down if i want Top end power then i move the clip up) the third clip starting from the bottom. the way i did this was loosen the carb clamps take of the seat and airbox lid Moved the Carb so i could get to the top of the carb removed the carb top and then removed the rubber bladder with my Pinky (pay attention at this Point because its delicate if you hurt the rubber diaphram your cooked.

5.Rode it for a while then checked the Plug it Looked Pefect (Light Golden Brown)

final Outcome (runs great now)At first it would only run 42 Mph with the 22 inch tires,,the 25 inch tires slowed the Speedo readout 5 Mph i took it out on a dirt road and it Ran 45 Mph on the speedo add 5 mph and you come up with 49-50
Thats all this 4 wheeler will do it was rapped out as tight as it would spin. has good bottom end and decent top end.

 

It would seem that not everyone is able to use the same process/parts to arrive at an acceptable result.

One guy posted that he loosed his gas cap, retightened it, and all has been well. Others have rejetted numerous times. How many holes have you drilled in your airbox lid?

I have been reading threads and searching this topic for a couple of months now. I still have problems, glad you don't. I have changed the mainjet all the way down to 135 and still have a rich condition on the top end. Can't really be sure if I need to invest in a K&N or Uni vs. the carb internals that Polaris Will has posted.

Our Hawkeye will run like mad , WITH NO AIR FILTER IN PLACE. Put the air filter back on, not the airbox/fenders, just the filter and no dice, stalls and bucks over 1/2 throttle. New filter, no dust, no mud.

06LimitedPred...What jet did you end up using? Did you replace just the main? What elevation do you typically ride? I saw your question asking if large and small head mains were interchangeable... Did you end up with 142.5 or something different?

After dealing with this on my wifes quad and the idiots at Polaris,,,,my buddy found the fix.

HERE'S THE FIX...........
If your dealer won't replace the jets and wants to drill holes, keep in mind the jets are under 10 bucks and the labor should only be about 30 bucks or so I was told. I'd rather spend the cash than have 6 holes in my airbox.

Carb Pre 3/7/06--------------------------- Carb Post 3/7/06 (The right one)
Main jet 147.5----------------------------------- Main jet 140
Pilot jet 42.5--------------------------------------Pilot jet 45
Jet needle 4HB42-5-------------------------------Jet needle 4HC57-3
Neddle jet 04-m-----------------------------------Needle jet 05-m

Post 3/7/06 Altitude--------------------Below 40 degrees F ---------------Above 40 degrees F
0-6000 feet ------------------------------------145-----------------------------------140
6000-1200 feet------------------------------- 140------------------------------------135 or 6 1/2 inch holes in top of airbox....(stupid)

According to Polaris the dealer can either replace the jets or (stupid) drill 6 1/2 inch holes in the top of the airbox and you can self adjust by removing the rubber plugs in those holes, again (stupid)
As far as the sparkplugs go....it should have an NGK CR8EB, if you can only find the CR8E like me. Then you can get some little top thing that screws onto the top of the plug, and your good. I'm not a mechanic so I don't know what they're called. Just make sure when you change plugs to change the tip.

Hope this helps....it got ours to run perfect. Except for the wife buried it in the mud and got the filter soaked, which caused the plug to foul up. One Unifilter and sparkplug later....Perfect. When they run they're great, almost unstoppable for their size.

 

Hey man I know it's been a while since you have been on here. How many hours were you at when it started acting up like that?
