I didn't make a Dealer appointment since after two past attempts the Dealer still seem preplexed...So I cleaned the T-bap using CRC aerisol MAS cleaner and the idle problem got much improved but on about the eighth fan OFF-ON cycle, the engine stumbled then stalled again... This caused me to then 'synthetically' adjust the rpm up from about 1,170ish to about 1,250-60ish by turning the throttle cable nut near the throttle body behind the seat panel...
Once the rpm then settled in at about 1250-60ish, and the fan came ON the idle-stalling problem dissappeared completely (!!) and the engine seemed much smother and much happer at this new rpm!!.... A later check with the dealer validated that the factory idle rpm spec is in fact 1,250....However, although the engine was waaaay happier at 1,250rpm and also quit stalling whenever the fan kicked ON, when I moved it from Park into HI gear the belt began to squeal and the tranny lever was very stiff and reluctant to move...
I later happened to mention this to a quite knowlegable forum member, 'Rush 2252' and he suggested that one possibility is to check for improper belt alignment causing excess drag on the belt - now noticeable at this new higher rpm... Belt alignment was fine, but there was no belt clearance or play at the primary side - it was tight (not good)...Rush said it should not be tight and to take the belt off to see if the pully center bearing was turning freely as it should - I did and found the center bearing was froze and markedly pitted, causing the squeal at the new but now normal idle rpm of 1,250...Thank You Rush!!!!
So I removed the primary clutch using a clutch puller ($35 at dealer) and took the clutch to the dealer for rebuilding...
So what happened??..... I'd just recently purchased the machine but did not know its history... Apparantly, the belt had began squeeling for the previous owner, and rather than addressing it, he likely lowered the idle to below spec to a point (1,170ish) where the belt squeal went away... The machine still ran perfectly, except that at this lower 1,170 ish idle speed, it would stall out whenever the fan decided to kick ON!...
Many Thanks to the RZR Forum, and especially to AWESOME forum member 'Rush 2252' for patiently guiding me through to determine the true root cause of this idle problem, a cause that even elluded the willing and reputable Dealer!!
