Hello All! Yesterday after a 45 min ride on my 2013 Can am RT; and a 30 min rest my wife and I started home. Within 10 sec of starting the engine and shifting from reverse to forward a very loud backfire sound came from under the seat. Neighbor came out from within their houses!. A bit of smoke, and a light spread of warm liquid shot out from under the seat and hit my left calf. The trike of course shut off and I turned off the key, too. An odor of burn rubber and exhaust was briefly in the air. Very shocking! Looking under the seat the gas cap had been blown in half with the top half well off its place and the bottom half still on the gas tank. After a few minutes I tried to start the trike and it kicked over and ran a few seconds...as if a little gas had been put in carburetor and quickly used up, and the engine failed to stay on. This happened a couple of times before a gave up. The bike was fully serviced about 3 weeks ago. There is normal oil level on the dip stick still. I needed to get the trike towed to a dealer who is not open until Tuesday. This happened Sunday and it now Monday 2/15/21. What happened and what am I in for.... any guesses.???? Anyone experienced this too!!
