plugs almost white
ever since i got my bike, about 14,000 miles ago and 4 years, its always been sluggish from a dead stop. the plugs are leaning towards white but with todays gas i figured that was it. it runs fine, doesnt run hot, the pipes are black and sooty inside. ive tried adjusting the accelerator pump and it helps some. i bought the bike from a guy in arizona and have always figured it was setup right. now wounder if ive been running lean all this time. where do i start, its a S&S Super E.

I'm currently running super E on 2 bikes. My plugs are a very light tan and sometimes just off white depending on outside temp. I live near sea level and I'm using a 29.5 intermediate jet, 72 main jet and idle mixture is between 1 1/8- 1 1/4 turns out from lightly seated.
When I lived in Montana I used 28 intermediate and 70 main with the same idle mixture setting.
My engine is pretty much stock tho I have free breathing pipes with baffles.
You could have a timing issue. Or maybe your bike is tall geared so taking off seems under powered. I had a 93 Heritage that was that way. The rear sprocket was a 65 tooth if I remember. Most others at the time had 72 tooth sprockets. I always thought it was under powered since it was new and I lived in Montana at the time.
Hope this helps!

just my 2 cents.......
check for a manifold leak. when you crack the throttle, you create high vaccum, and with an intake leak, it sucks more air, leaning out the mixture. would give you a hesitation for sure. beyond that, might just be the jetting. i know mine is much more responsive now after jetting up one size, slow and main.
