edge 01-10-2003, 09:02 AM l'm having trouble with my 99 polaris 600 this year it won't idle unless the choke is on and as soon as l get on the gas it backfires more. lt has a boost bootle and changed the needles from r1368-g to r1371 last year and had no problems with it.l need help with this and under the exhaust is black. thanks retiredpop 01-10-2003, 10:06 AM Sounds like the pilot jets may have gotten gummed up a bit during storage. Pull the carbs and unscrew the pilot jets to clean them properly. OMOTM 01-10-2003, 11:07 AM Sounds like an air leak. Check your carb boots carefully. The backfiring is caused by a lean condition, which you add less air when the choke is engaged. RIDE SAFE Alaskan RMK 01-10-2003, 11:46 AM You might want to check your Reeds. If they are weak or chiped, they will make your engine run lean. You should be checking this once a year. madsledhead 01-10-2003, 01:22 PM Seems to be lean at the pilot stage. Look at your pilot circuit. Probaly have a small bit of crud in the pilot jets. | ||
