V7C Evap Canister

When I got the recall notice for the faulty valve in the evap system, I had the dealer remove the entire thing. Visually, it makes a real difference without that black can hanging under the engine.

I have a question for any V7C, Cafe, or Racer owners that have also removed the evap system. Did you notice any changes in the way the engine runs? My bike was running really great before removing the evap system. It was running better than it did when it was brand new. With the evap system removed, it seems to run even better. I know that should not have made any difference, but throttle response seems better, popping on deceleration is gone, and we were able to lower idle rpm by a couple of hundred rpm. Idle was at 1100 - 1200 now it is at 900 - 1000.

Does the evap system affect the balance between the throttle bodies?

I should also note that the bike has 9500 miles and I had a MemJet intake air temp spoofer installed at 3400. I also have Mistral exhaust cans installed.

My 09 V7C is bone stock except for the smaller crossover pipe. I had mine de-canned at about 1200 miles and the throttle response was an immediate improvement as well as it became easier to start. I now have 20,000 miles of smiles on my bike and it runs great without any add power boosters. Depending on my riding for that day, either just cruising around or carving the twisties (most of the time :twisted: ) I get between 50-65 MPG, also the motor is never running under 3500 rpm, mostly 4000-5500 rpm.

The canisterectomy on my '11 V7C was performed at the 600 mile service last month. Aside from the improved cosmetics, the bike does seem to start easier when cold and maybe, just maybe, rev a bit more freely once I'm on it. Tough to imagine the surgery had anything to do with it -- perhaps the engine is simply loosening up a bit.
