Are you using the choke to start it - the choke on these bikes will foul the plugs quickly. Plugs on these bikes will last over 100k an just clean them with WD 40 and a small brass brush.
read this.
It ain't no joke if you use that choke!!! Don't use the choke.
I don’t know why but it seems that a lot of bikes run fine when
new but after a couple years they seem to start having trouble.
OK some may be able to get away with using the choke but that
may have to do with when the set the carb during assembly.
However most of the time when someone is having trouble
starting their bikes it is usually due to using the
choke/enhancer and fouling the plugs. The choke in these bikes
isn't like the old fashion butterfly you are use to on older
types engines. The choke/enhancer actually dumps a whole lot of
gas directly into the cylinder and fouling the plugs. This is
all caused by the manufacture setting the A/F lean (1 5/8)
turns open to be able to pass EPA standards. If you set the A/f
at 2.5 turns open - most of the time you will not even need to
use the choke even when it is cold out.

Not using the choke, learned my lesson. First morning I had the bike, started it up, seemed to be cold blooded so I pulled the choke out part way and rode 3 miles to work. Seemed like the right thing to do, I have 6 dirt bikes and use the choke all the time. Anyway bike started running like crap, fouled the plugs so I changed them out. Lesson learned.

Add glen's above, and the it will be better in the cold and will start and warm up much faster.

Doesnt hurt to use the enrichner, if you use it right.
I have used mine when its cold out and have been useing it since May 20 of 2002 when I got the 1300.
I dont know what everyone elses problem is. Maybe they just dont understand, or, just dont get it. :cheers:

There has been so many over the years that have had a lot of trouble with using the choke especially when it is cold bike/weather. Some are set so lean from the factory that if the temp gets down they wont start. Mine was terrible when the temp only got down to 50* and now I only touch the starter button to start it.

Mine has been rejeted a few times.
some guys have to use the enrichner some times.
so why not tell them how to use it, if they have to, Instead of telling them, dont use it, you will foul you plugs?
I have never fouled a set of plugs from useing the enrichner, I have fouled them by putting to big of jets in and going up in the mountians.

The more you pull it the more fuel you are dumping directly in each cylinder and soaking the plugs. Remember that if you twist the throttle it also increases the amount of fuel plus what the choke is dumping in there also and with that combination the chances of flooding/fouling will increase. And also if you wait on using it you will still have that opotion. The choke is being used especially on new bikes because of the factory a/f being set so lean fron the factory.

This is correct, the more you pull it out, the more fuel you are dumping in, alot of guys, pull it all the way out and ride for 10 miles :nono:
Most of the time, it only takes about 1/8 to 1/4 to get the bike running when its cold, then you push it back in.
As I said, most of the guys, dont know how to use it.
They think its a butterfly choke, but its a enrichner. Totaly different.

correct, due to the fact that it drops the fuel downstream from the butterfly and slide after pulling the cable out, therefore enrichening the mixture

Looking at the sealing area of the two plugs, it appears the torque is a little low. Wishing you well.
No butterfly, its a plunger.correct, due to the fact that it drops the fuel downstream from the butterfly and slide after pulling the cable out, therefore enrichening the mixture
I feel, that its better to explain how to use it, because of the fact, not all bikes are the same and some have to use it because of the jetting. Also, I feel its wrong to tell them to stop useing it because its wrong to use it. Better to explain how to use it. Just my .02 cents.

I haven't done the scar mod or installed glens a/f tool yet. I will use the "choke" when it's really cold out but I only pull it out 1/4 of the way or so and after the bike is running smoothly, I push it back in.

maybe i'm wrong on the 38 that honda runs, but the 40mm keihin carb still has a butterfly that fuels from the enricher comes out down from after the slide on the engine side. but i do agree with you on telling/not telling

i have never fouled plugs using the choke. i had to use it every time the engine was cold even when it was 95 degrees out. several times i have had to ride it down the road with the choke on to get it to run right. again i have never fouled the plugs using the choke.
you are right to explain how to use it. and it is wrong to say never use it. if the bike is setup stock youll never keep it running without it until it warms up.
