CHECK THIS OUT !!!

and the front one is running lean and the plug is bone white?? and I do mean
BONE WHITE. I have a 95 FLSTF and had the CV carb rejetted to (Ithink) a 180
main and 145 or 150 slow jet. ( I'll have to check again to be sure Ijust don't
want to get in there if I dont have to!) I would very much appreciate some
advise and suggestions A.S.A.P. before I manage to screw something up and miss
any of the upcoming riding season!
Thanx in advance.

you didn't happen to mention if the manifold was removed for any reason.
If so, you have a manifold leak. Also, check the exhaust, and make sure you
have no leaks there. For more, write me at MrSc...@delphi.com.

First thing I would look for is a vacuum leak. Probably leaking near
the front cylinder since it is so lean.

Saw a tech tip on this awhile back. Check the intake manifold for cracks and/or
proper seating to the cylinders.

I am, but the last time I checked, an intake manifold leak is a vacuum
leak.
So, isn't it................. Vacuum Leak: 4
think about it,

rejetted the carb was because I had installed Python II drags w/HP Baffles and
a SE Airflow kit to boot. So the engine would not run to lean as a result of
this I rejetted the carbs too (had that part done cuz prior to that day never
worked on a cv carb before, and didnt want to screw anything up...go figure)
Thanx again

be sure its torqued right though just incase.

Ok, Intake manifold leak: 4, other causes: 1
(what inning is it?)

So in essence you paid somebody else to screw it up.
So now you got half the fun at twice the price.

I don't think a leak in the intake manifold would cause such an extreme
difference between the fron and rear jugs. Perhaps there is some sort
of valve problem. Are you running a stock valve train? If you have
adjustable pushrods I would check that. Are you running stock
ignition? If you changed the trigger plate you might want to look at
that. The first thing to check is the valve train. The reason I would
not suspect a leak in the intake manifold is that the runners are so
short, there would be no isolation between the front and the rear
cylinders. I could be wrong but it just does not seem logical.

Greg,
180 on the Main seems large but with P II's I have no idea, it would be for SE slipons. I had this problem on a Bendix once and the problems was the gas stream was pointed more toward one cylinder than the other. Might check your coil.
later,

>rejetted the carb was because
i read a post a while back that dealt with a similar problem, but it
wasn't a manifold leak. the problem in the other post was unequal fuel
distribution to the cylinders caused by a misdirected main fuel nozzle.
this was diagnosed by a visual inspection of the spray pattern observed
when the throttle was rolled wide open. the solution, as i recall it, was
to CAREFULLY turn the main fuel nozzle in the proper direction with
needle nose pliers to give equal fuel distribution to both front and rear
cylinders. it may be a long shot, but not hard to check. somebody else
must have heard of this and can give better advice. manifold leaks are
often diagnosed by plug inspection, but they usually are evidenced by
cough and back spit , which wasn't mentioned.
the "i'm no wrench, but i read a lot" big easy said that.

I vote to check the Manifold First.
Learned a neat trick from an old timer to do this quickly.
Though it does make a real mess outta the bike.
Take a can of WD-40 and spray it on the intake manifold where it meets
up to the heads and carb. If you have a leak the motor will rev. up
in RPM's and a white smoke will come from the exhaust pipe of the
leaky cylinder.
WARNING!!!!!!! Do this only to a somewhat cold engine!!!! WD-40 is
very flamable!!!!! Stop doing it when the engine warms up!!!!!
Ron McBee
PS Not the best or smartest way-- But quick! makes a good starter fluid
in a pinch also
Dave Smalley
Isn't there something you spray on the manifold while it's runnin
to determine if there's a manifold leak by the change or lack of in the
way the motor runs?

>Greg,
It's not a manifold leak, your carb is leaking gas into the engine.
The gas isn't atomized, so it drains back into the rear cylinder. The rear
plug foul and misfires, and the front problably runs lean because someone
tried to jet the carb so that it would balance, and they couldn't get the
gas to drain equally into both jugs.
The solution stays the same, you take everything apart, carefully put
it back together and it works fine. Unless you've managed to aquire my old
shovelhead, in which case "running fine" will mean spitting flaming blobs
of fuel out of the velocity stacks onto your leg. But then again, you
probably can't look down the carburator into your engine, either.
Have fun.
