I'm trying to help a friend who's got a 2000 or 2001 Heritage Softail that complains how gutless it is power wise & gets pretty low gas mileage, probably in the low to mid 30's range. It's stock 88" with true dual pipes & SE air filter.
He's also getting carb backfires now since it's gotten cooler so I know it's running lean on the slow jet. I had the same issues when I first got my FXDL so I have an idea what we are going to be doing to fix his problem.
So he comes over, we pull off his a/c cover & it has raw gas pooled on the bottom edge. HMMM? Then we pull the A/C off, more raw gas. About a teaspoon or two. His mixture screw is out 1 3/4 turns. I pull the float bowl & I replaced his 45 slow jet w/ a 48.
I expect him to have a dealer installed Dynojet kit, but when I pulled the main jet & emulsion tube it doesn' look the same as I remember mine. The emulsion tube seems to look different & you need a special tool to get the 185 main jet out. I seem to remember the emulsion tube I had as being a hex that you could hold onto & use a screwdriver to remove the main jet. Check out the pic & help me figure out what I've got here.
I pulled the top cover & it has an adjustable needle w/ the c-clip on the 4th groove from the top. We moved it up to the 3rd groove to lean out the top end a little.
Put it all back together adjust the idle srew at 2 turns out & take it out for a spin. Definite improved power. All is looking good. Get back to house & out of curiosity pull the A/C cover to check for raw gas & sure enough. There is raw gas coming thru the hole the a/c cover screws into on the filter.
All that typing to get to this: Why isn't the gas getting sucked into the carb all the way & getting burnt & what can I do to fix it? Is this jet kit all Dynojet parts or a mismatch of Dynojet & stock or other mfr. carb. parts? Could his true dual pipes be a cause?
Also he has a puke tube w/ a filter on the end & a breather cross-over so nothing is being vented into the backing plate.
Sorry for the long post trying to give all the info up front.
