I'd put it in back of my truck, back through the front door of dealership, shoot the salesman.

Have you changed the fuel filter, spark plugs?

Are the 170's pull start? I've never seen one

 

they are a pain to start. I read on one of these posts about changing the jetting on the carb that makes it start and run better....(I have no idea, just repeating anothers comment).

I will say the kids in our group love to drive them......after the parents start them.....we have 5 170's in the group.

 

The factory jetting sucks! U need to change the pilot jet from a #35 to a #40. Will help with starting.

 

@hog they are electric start, if i had to pull start this POS i would have already blew it up
@hokie I have seen that post about changing the jets also, in my recent readings...

I really like the efi setup & may go that route cause i may be wrong be i dont think our crappy fuel will effect an efi like it does a carb

 

Sorry about your troubles with te 170. I bought my daughter a 2011 rzr 170 last year. It was terribly hard to start even in 70 degree weather. I changed the jets and adjusted the throttle cable behind the firewall. The little thing will start in 20 degree temperature now sometimes without even choking it. It also runs quicker and smoother. My daughter is 8 and starts hers by herself, even on cold mornings.
Before, I would have to play with it for 5 minutes sometimes to get it running and them as soon as it started I would take off and ride around the yard to warm it up. Now she fired it up and it will sit there and idle all day. By the way, I changed the pilot to a 40 and the main to a 110

 

I may have to try re-jetting it, something has to be done...re-jet, efi kit or set it up on my shooting range & blow the snot out of it ( which i dont want to do,as my son loves it when its running ) but at this point i think he may take pleasure in poking a few holes in it also...lol

 

Bumping up the pilot jet to a 40 will solve your problems.
These lil guys are jetted REALLY lean from the factory to meet EPA emission requirements so they can be imported into the US.
Polaris seems to be oblivious to this problem and they will offer little help on the issue.
I have personally done an EFI conversion on a Pitster and love it, although it was a bit expensive but worth it to never have to touch a carb again.
Contact Smartdave here on this board if interested in the EFI conversion, as he is putting together a kit for sale.

 

I will echo Danny's comments. If you want to stay with a carb then change the pilot jet to a 40, it really makes a difference and only take 10 minutes

 

Thanks guys glad i stumbled on this site BEFORE i used the little thing as target practice. You all saved a service manager and salesman from a dog cussing they was about to get today...lol
You all have gave me hope this little thing can be saved

 

I will say they are great machines and have a lot of potential.

 

We had the same issue on cold starts just like most others from the get go.. In our case finding out that the valves weren't set correctly. .003 intake-005exhaust. Made a huge difference. One click and it starts. The valves were so tight they never really were all the way closed. Cold and no compression doesn't work well.

 

Ok you all have talked me into putting a little more cash into this thing. So far i have decided to get the Big Gun Evo exhaust kit & am going to rejet the carb to 40 & 110. Also i seen the diy cvt snorkle & might do that also as its cheap & easy.
What other mods are recommended for performance & relialabilty (mainly relialibly..lol)
Also i am in Texas so will the 40 & 110 jets be good for here, not sure of the elevation but we are not real far above sea-level couple hundred ft maybe.

 

Start out with the 40 pilot jet first as the pilot will increase fuel throughout the entire throttle range. If thats not enough, bump the main jet up a tad.
A 40 pilot seems to cure most peoples problems ........

 

Danny thanks...will this bigger jet also solve the jet clogging issues when it sits a little while not being run or is an EFI the only way to solve that issue?

 

The clogging is due to the crappy fuel we have. When you buy fuel mix it right away with stabilizer. Also if it will be more than a week between rides drain the carb to ensure you never have an issue

 

I use Sea Foam in my gas can's and tanks on all my machines, it stops the gas from turning into varnish in the carb's when it sets for awhile. Our fuel is poor grade and goes bad in short order, Just my two cents.

Sled

 

while waiting on the new jets to arrive i noticed the fuel pump appears to be dead. This is the 2nd one now in less then a year....
Is there an aftermarket replacement for it as i dont seem to have any luck with the polaris OEM one or if not where is a cheap place to buy an OEM one as this is getting pricey buying an $80+ dollar one every few months

 

fuel pump died? I didn't even know that was possible. Did you open it up and see the seals bad?

 

Well i pull the hose off the carb & turned it over...no fuel comes out & i know its not the filter cause i even pulled that off... so i assume it died & i also assume they can cause the dealer already changed it once.

But i have not opened it up yet to examine it, just fixing to do that

 

What about something like this ... Mikuni Geniune Pulse Vacuum Fuel Pump Rectangular DF44-227 Odyssey Snowmobile - Intake & Fuel Systems

 

Yea thats what i was looking for....i knew i seen them cheap somewhere but my search come up empty...thanks man

 

Was the fuel switch on? Fuel in the tank? did you crank for a good 15-30 seconds?

 

I know that my pump (the vac one not the electric one) will fill a 20oz diet coke bottle in about 20-30 seconds

 

The switch was on & it did have gas. I stuck a stick in it & it has maybe 1/4" of gas in the tank, BUT i just filled it up & it started pumping. Guess it dont pick up the last 1/4" & i even tried it on reserve and it still didnt pick it up.
But another issue fixed, thanks man you been a great help.

 

Now i wonder if the dealer didnt rip me off for $200 when they replaced the last one....

 

I am not going to speculate either way. However...... There is so little to break in those pumps. There are only like 2 moving parts

 

Ok...one more question. I ordered some jets & I didnt order the right ones cause the ones i received are way smaller(in size both length & diameter). I ordered jets for a 22mm carb (got that out of the owners manual). Since there is no return on jets i am back to step 1 again, before i order another wrong set can someone please tell me what to order.
