I've been through this vent mess for over a yer. Never fill it after the auto shut off at the pump.
Dealer has been great, BRP seems to try but zero results from parts changes, etc.
Canisterectamy and vent run to the rear to keep fire potential to the minimum. Bottom line is it still drips,
smell is horrible 1/2 the time and I have to leave the garage doors open a couple hours. I run a 24 inch fan suspended
and aimed at the Spyder most of the time. This is the only continuing problem on my 2011 Spyder RT in 25,000 miles.
My daughter won't let me park in her garage due to the stench and fire hazard.
The only reason it hasn't acted up in the last 6 weeks is my not riding it due to a shoulder operation.
I really love the Spyder, but I cringe every time someone's bike catches on fire (admittedly, this has lessened, probably due to folks
not filling up like we should be able to.) The dripping varies from a few little drops and tank recently filled (to about) 5.5 gallons or whatever, to varying quantities - down to almost empty, to lots of dripping and BIG gas spot on the road or cement.
The good news is that the garage is detached and hopefully the house won't burn down.
My new gas cap is sitting on the seat until my next ride, maybe next weekend if the DR gives me a thumbs up. Gotta put the new red sway bar put on also. Maybe the combo will stop the fuel problem, nothing else seems to.
