Fuel pumps usually have rebuild kits available. A broken diaphragm will act as you've explained. Using non-ethanol fuel is best along with 91 octane minimumUPDATE to above: I got it running with the spare carb. Fuel pump seems fine. I sure had an issue getting the float pin out of the spare carb too....drilling the pin, tapping, Dremel tool to tip of the pin, tapping, repeat, repeat, repeat. I finally got it out. New needle/seats in both. Drained the case through the impulse line port. Seems to run fine. I'm going to try running AVGAS from here on out. A lot of my collection sits a lot and ethanol gas is causing a lot of time replacing hoses and stuff!
I'd still like to know if all '98 Polaris skis were the same as the XCR so I can get mine back to stock.
New to the machine and have made changes. What were carbs bored to? V-Force won't gain much if anything. These sleds run hard when tuned well.Just had my motor on my 98 xcr 440 redone. It's now on 110 race gas, carbs were bored, vforce reeds. I plan to hill climb this sled and I'm looking for any insight on jetting it and possibly some clutching ideas. I'm new to this machine.
Best to vent them to the airbox under the shelf. This is a change from factory stock. More consistent, better running.Where should the vent/vacuum lines off the sides of my carbs go? Been reading around and haven't got an exact loacation yet. Thanks
Hot Seat (HSP) helixes are difficult to find. The 52/38x is too much helix for a 440.Thank you sir! Also having a very hard time as far has finding the hot seat 52 34s helix. Is there something you may now that's comparable to that? I found the 52 38x and seemed to have good reviews on it. Thanks again
