Starting Hesitation

I've had my wing now for about 8 months. it is an 02 with about 10,000 miles. One small gripe I have is that when I start it, I have to usually hold the throttle open just a bit for it to fire.... or I have to hit the start button 2 or 3 times for it to start. Does anyone else experience this or am I just the lucky person. Being fuel injected, I wouldn't think this should ever happen. Even on my 05 Helix this never happens as it also cranks right up. Any ideas?

Hey Ron,

Just a thought...replace spark plugs, check air filter. I'm also thinking fuel system pressure. It might be a little low or injectors might be sticking.

When it's idealing or running at medium to high speeds, how does it run?

Air Filter was just serviced. I installed fresh iridium plugs in the spring. I have a membership to HRCA so I could look up the procedure for checking fuel pressure in the online manual. The interesting thing that I forgot to mention is that it only does it when it hasn't been run in a while such as overnight. But if I ride to the grocery store at noon and then say go for a ride to the video store at 4:00.... then she'll crank just fine. I did run some STP fuel system cleaner through some time ago. i just divided it into fourths and it gave me 4 treatments which I ran back to back. Didn't make any difference. Thanks for the suggestions. I will see about checking into the fuel pressure.

One more thing, when was the last time you replaced the battery. Some times the battery will crank the motor and not start it. Overnight an old battery will drain down a little.

I noticed some hesitancy in acceleration after 10,000-15,000 miles and a couple of times needed a second ignition to start.

I started adding a couple of ounces the AMSOIL P.i. Performance Improver ( http://www.amsoil.com/storefront/api.aspx ) to the tank until used. I found the SWing much more responsive and I saw the MPG increase the first time. I have not had to use a second ignition since.

I am not an Amsoil dealer ... I just sign up for a preferred discount ( http://www.amsoil.com/a/wholesale-preferred-customer ) when I order in bulk.

I would only re-add treatment when I felt any hesitancy.

Since adding the Dynojet Power Commander and using the European Stock map or the my Johnny Cheese custom map, the hesitancy frequency has occurred a lot less. My current theory is it could be due to the gas or gas additives added by the refineries. The Power Commander maps above reduce the amount gas injected which for me has greatly reduced hesitancy occurances. Now I only add the Amsoil PI as needed and only for a couple of tanks and stop, which is all I need till the next time.

Battery was replaced last spring. I'll still see and check on the fuel pressure. Bill... I also use amsoil synthetics and have the preferred customer discount. I was looking at the 0W-40 they had and was thinking about trying that in the bike. I usually use either the 10-40 motorcycle or the scooter oil.
