I was just wondering if this is a normal occurance for these 98 XC 700's.

I've owned 2 of them, and they both seem to have these symptoms:

1) When starting it in the morning, after I pull the chord, it will miss and fart (not as loud as a backfire), just a pooof like I'm blowing air through the muffler, but won't start. It does this 4-5 times, then manages to start.

2) After riding the sled and then shutting it down, if I wait 2-3 minutes and try starting it again, it won't start right away. I have to pull 3-4 times, and even then, when it seems like it'll start, I have to give it some gas to keep it at idle.

Thanks for your input.

I had a '98 XC7 also, and I remember the ill starting, and low speed driveability issues that you are describing. I remember going one size larger on the pilot jets which helped a lot. ( you may only need to richen up the air/fuel mixture screws). One note on the '98's, they never came with a thermostat. Polaris had an update kit which added the thermostat. The kit was many pieces, and took me all day to install. The kit was about $125, but what a major difference! My sled would start with a couple of pulls, and would only have to rev the sled cold for a little bit, than it would idle cleanly. All the cold "popping" while trying to drive at low speed was gone. Good luck,

Thanks for your reply.

I'm definately not a mechanically sound person when it comes to sleds. If I was to bring it to a local shop to have them increase the size of the jets by 1, how much would something like that run me... $$$$ wise?

Thanks

I would take a guess about 1.5 hours of labor to change the pilot jets. I would talk to your local dealer first, and explain your problem. The pilot jets might not be your specific issue. I would feel bad if I helped you spend $80 in labor changing jets, anf later finding out you actually had a $2.79 fouled sparkplug! LOL

Hehe.. it's definately not a fouled spark plug.. as once she gets going.. she's going good.

Would it be bad to leave the sled like this for awhile; farting, burping.. pooofing at startup?

Thanks again.

I would have your pilot jets increased and also have the dealer set your timming as well. your engine timming is important. a tune up is what you need, BUT make sure you stress that you want the pilots increased and your timming checked.
