I got my Boost back from my dealer after having the fuel socks, clutch bolt, and fuel tank recalls done mid-December and my engine seized on my first day out on 12/19. Crank bearing failed, engine seized, had to tow out on a crazy deep day up on Buff Pass. Dealer has warranty approval but Polaris is having them rebuild (vs sending out new bottom end). I've been all over dealer here in Denver and they are now saying they have all parts except the crank seals. Backordered from Polaris, no ETA, said they checked dealer network as well. Part numbers are 5417255 and 5417863. Anyone know if these are on a serious backorder or more readily available if I do some digging of my own?
Thankfully I've still have my trusty Axys 800. Boost was stock with a Diamond S and intake mod to help bogging. One thing after another....... Have read a few threads on crankshaft failure but hasn't been nearly as big of a headline as all the stop-rides. Curious if anyone else has had their Matryx 850 NA or Boost seize at low miles (400 miles). I've seen TRS post he has seen it a number of times under 1,200 miles or so. Boost was running so ****ty end of last season (even after doing fuel sock mod), I was riding the Axys more simply for reliability sake. Broke it in properly, it did run great of deep days for the first half of last season.... but here we are
