another jetting question

[Rick Fortner]

2006 1700. Freedom Performance true duals, K&N filter and aluminum intake. I have attached a pic of my spark plug. Looks to be running rich to me. The pilot jet is a 37.5 and main is a 170. I know from reading here that the pilot should be 40 and main should be 172.5. I do have to run with the enricher out for a bit to get the bike to run without hesitation or stalling. Could this be why my plugs look like they do. Should I change the pilot to the 40 and go from there or change both jets to start? any help with this is appreciated.

also the needle clip is on the 4th groove and has plastic spacer and no washers.

check to make sure the pms is set at 2 1/2 turns out at most and make sure the air filter is clean. if that plug was pulled without idling for a a while with the choke pulled there is a problem somewhere

[Rick Fortner]

I think that is my biggest problem. I do have to idle for a bit and run with choke out for a bit. All 4 plugs look about the same.

[davej]

Using the choke for a couple minutes or miles is normal. What I meant was do not idle it prior to pulling the plugs. Just go for a nice ride maybe even up to 10 miles or so. When you get back home shut the bike off immediately without letting it idle, let it cool down and pull the plugs. You only need to pull the outside 2 plugs no real need to pull all 4.

Dave, when you say outside do you mean the front or rear plugs?

[Brad_G]

I think what he means is the left (kickstand) side of the bike. You should be able to get those out easily without removing the tank. That way you're checking both cylinders. Unless you have a coil/wire problem both plugs should look alike in their respective cylinder.

[davej]

Brad G is correct that is what I meant. front and rear plugs on the kickstand side.

[Rick Fortner]

On cooler mornings in the 40s i can let it idle for 10 minutes and still have to ride with choke pulled out at least partially for another 5 + minutes.

[davej]

that is normal in those temps

Thanks guys!
