Stalling at cold starts - circuit breakers didn't help - so I started to focus on the emissions - thought I'd by pass the canister and leave the tank breathers at atmospheric pressure to avoid vapor locks during cold starting - didn't want to void warranty, leave purge valve working normally - it looked easy in Manuel (but not) - breather hoses on tank are hard molded plastic tubes and getting to purge valve and canister not so easy peasy - solution, disconnect tank breather hoses and plug them up good - next run automotive flexible rubber hoses from tank vent to the bottom- emissions system still installed, warranty not voided, seems to behave itself during cold start up - besides, even California has done away with motorcycle emissions - hell, Texas doesn't even have a decibel standard for exhaust
When I pass the 2 year mark, I'll do a more permanent - better job

I don't think the evap system has anything to do with it. Many FTR's don't have it and still have the cold stalling issue. It's the stock tune. 😢

Ours don't have the evap system in the UK and cold stalls were still prevalent.

Sadly the only thing you can do to fix the issue is a tune.

My bike never had the evap junk and always had cold start issues till the tune.

That would be very weird if your bike doesn’t have the canister

My mistake but easily missed, mine is there gloss black but no labelling as the one depicted below. Picture paints a thousand words. California and Euro only have it supposedly?

Certain regions don't have them, Oklahoma for example. Pictures from this very forum.

California and I believe one other state in the USA require them. The rest of the states they aren’t required.

And I believe every country other than the US requires them.

I can feel my bike killing the ozone as I ride it without one!

Basically if I understand correctly:

593944


  • Pry/pull the three hoses off the canister.
  • Remove the canister.
  • Completely remove the blue hose, it's just a vent for the canister.
  • Block the yellow one between the canister and purge valve, this one must be closed.
  • Block the black hose that ran to the canister at the T-type connector you'll find roughly where the blue hose crosses the black one AND open or remove the cap below/under the engine next to the regulator (make sure this hose is open somewhere, this is the tank ventilation! Ideally as low as possible)
Done.

I have yet to test ride it, but so far no check engine lights or fault codes...

Check check double check.

Took her for a ride today, no check engine lights, and ran exactly like before. The above works 👍🏻

Even with a good tune there's hardly any extra ponies to be had worth talking about. Talking of 'torque' your curve and delivery will however be greatly smoothed out hopefully? I have had the cat deleted since day one and by complimenting it with a K&N filter you get a discernible growl from both front and rear ends.

Is anyone please able to confirm? With the evap system and canister removed does this improve the prolonged refueling process at all? My dealer seems to think it might? Thank you.
