Symptoms…bike would idle fine…no engine codes…when cold it ran like a bandit…as soon as the fan come on it acted like it had a rev limiter and would tach 4950 rpm’s and no more…funny thing no bogging, backfiring etc….turn the key off for 20 seconds and she would run fine for another 2 minutes.
After researching the forums I leaned to a bad fuel pump and tore her down.
I know a lot of members offered advice & choice of fuel pumps…I went with this seller on e-bay even though I’m not an e-bay fan…all he sells is pumps and reviewing the feedback other polaris owners were having luck with them so I ordered & had it in 2 days.
Fitment was fine & came with a free strainer…only issue was the ground wire was now a tad short so I spliced/soldered & used heat shrink to add a longer lead.
While I had her apart I did replaced the plugs and upon inspection noticed the clutch side wire rested on a head bolt..sure enough from vibration the wire was almost exposed…keep an eye out for this as I see this a potential problem down the road.
Got her all back together and took it for a 2 hour run before I put the front pain in the butt plastic on…it’s over 90′ here..runs absolutely perfect…pure joy.
For others here is where I got the pump..$42 + free 2 day ship…my bike….2004.5 Sportsman 700 efi.
