2020 slingshot R smoke from exhaust after gassing up after highway driving 65 mph or so for around 30 miles did it on acceleration one time couldn't reproduce, smell of oil burning for sure. Tried to reproduce under same condition with no luck. Starting cold in building no smoke even with increase in rpm. Today driving 65 about 15 miles or so heard ticking about 8 times in a row from engine then smelt oil, stopped and accelerated produced smoke again got a video for dealer. Drove back hwy driving no smoke seen, but on stop then acceleration got heavy smoke. I had contacted dealer and Polaris knowing that if they couldn't produce the smoke nothing would be done but to give a heads up there was something going on. I am really wondering if it's pulling oil from the pcv system at higher speeds sense it hasn't smoked on start ups but just a guess. Today dealer advised they would contact Polaris Monday to start a case and see if they were to have the SS picked up or drive it to the dealer most likely picked up not knowing what is going on. Also as others have noted the front crank seal is sleeping after the pcv recall and adding the extra qt of oil . Still under warranty for now, good sign I will buy the added 3 years of warranty. I'll try to keep posted what is going on with the machine.
