Carb tuning is not really difficult, just a little time consuming. The proper main jet and jet needle clip position will cure most if not all problems. Sorry your dealer can't help you. Maybe study up a little on carb tuning and get it running well on your own? That's what I do.

 

Thanks, sheepdog - I just had to vent a little, you know? When I decided to buy the Hawkeye new, I just figured that buying a new bike would avoid any problems..... hence my frustration. You know anywhere I can get some info on carb tuning for my Hawkeye? Any direction would be appreciated!

 

michaelsimms:

I had to jet mine down from 147.5 mains to 132.5 mains. I ride between 5000 and 9000 elevation though. I would think that if you ride around 2000 to 4000 feet, the 137.5 would be good. Do you know what is in yours?

Also, I had to raise my needle as far as it would go (put the clip in the bottom slot) because it was running to lean in the mid-range. Polaris sure got that right didn't they. Lean in the mid-range and waaaay rich on the top.

Good luck with it.

 

Sledboy,

Tri-City did their testing on my Hawkeye. I bought it last Dec and they had not done any tuning testing yet. In the spring after trying to use it twice at the "B" I took it back to them and they said that they still had not done any testing so I told them to use my machine to get the testing done,and that I did not want it back till it was fixed. The changes they made seemed to work on my machine, it now runs great and I have had it up to 9000 ft.


they also changed my clutch to roller weights.

Have fun.

 

the owners manual for all my quads have jetting charts and clutching charts for different altitudes. I would suggest referring to them, if you are at over 4000 ft. the jetting needs to be different, and sometimes the clutching. The smaller machines are more finiky than the big bores, and the other thing is how does your sparkplug look? If you have a jet so large as to make it smoke feel lucky it got you home. If you make a jetting change, change the sparkplug, and take a look at it as it is the best way to see how a four-stroke is burning.

 

If you do refer to the jetting charts as suggested remember that Polaris has revised the jetting chart which is on the website in the downloadable owner's manual for the Hawkeye. The chart in your owner's manual is now incorrect. They missed it by 10 jet sizes. A new record.

 

Don't necessarily go by the manual. Since the Hawkeye was released, they have released two different updates to the manual and the jetting specifications it contains. So if you go by the manual without going online and checking the updates, you will be back to the same problem, way to fat of jetting and a machine that will not run.

I rejetted mine last night from the 147.5 that it came with down to a 137.5 main jet as is now specified in the online manual. I also raised the eclip from position 5 up to position 4.

It runs great with no sputtering or stalling upon hard acceleration anymore.

 

Excellent! Glad to hear it. Hopefully you and I both will not have any more problems with them. Now if I can only get softer springs for the rear end so my wife can stand to ride it.

 

I have also heard that there is a replacement needle that polaris is specing for the hawkeye. I am gonna get one andsee if it makes any difference.
