banshee idle problem
Berkeley Spencer
next it's racing .It's very diffucult to ride when you cant slow down to
anticipate a jump.
I know to how to adjust mixture, but how do i know when it's correct?
can someone guide me through the process.
Why does it race when it's about to run out of fuel.
It also uses loads of fuel i.e.a tank full in about 2 hours not constant
riding flatout.
The tors has been disconnected but not removed.
What carbs would you suggest for best mid-top grunt.
also it is very flat off power band.
This is a stock machine for the moment!
THANKS IN ADVANCE

You're either too lean or two rich down low. I forget, does a bansee
have dual carbs? If so, they could be out of synch. Synching carbs
is easy (I've never done it on a Bansee, though(
What I do is take off the air box so I can see the slides looking into
the carb. Then I put a q-tip in each one under the slide so that when
I move the throttle, they "bobble". Then I adust them both so that
the q-tips bobble at the same time.
If it's mixture, hard to say. Did it ever run right? Did the temp
suddenly get very cold or warm in your area when this happened?
I'd clean out the jets/carb, synch the carbs, then start fiddling with
the air/fuel screw. Also, check for leaks around the intake. Start
it up, spray wd-40 or something like that (silicone spray works for
me) and see if it causes it to increase in idle.. if so, leak city.
Fix that before tuning carbs (but you can synch first).

Here's one of my favorites:

Because it's running very lean. This isn't good for a 2-stroke.

How big is your tank. Sounds a little fast. My 250R with the stock
2.5 gallon tank took about 3 hours.

Find a banshee user group and ask there.

What does that mean? When the pb hits at higher rpms it flies, but
before that it's dead? That's a bansee for you. All or nuthin.

not stay adjusted-seen this happen to a dude before. Synch the carbs(not too
hard to do & easier with the airbox removed so you can see what you're
doing). A good carb for mid-top on a stock machine would be Keihin 28PWK's
and they will fit into the stock manifolds more easily than bigger carbs,
also use reed spacers to avoid clutch cable clearance problems(a trick I
learned from this NG); install new torque reeds while you're in there too.
The aftermarket carbs will help a ton as long as your motor is ready for
them(check cyl. compression and make sure it's even or close-don't recall
what lbs. tho, get a service manual) and they will eliminate the TORS units
which can also be done with a kit that retains stock carbs but the stockers
are basically garbage and bind up the potential of the motor. Also you may
want to modify your airbox lid or run pods-I removed just the snorkel and it
worked out great as I don't like exposing too much of the filter to the
elements, oh yeah-spend the money and invest in a proflow K&N setup as it's
much better than the stock setup which doesn't seal for shit(use a
pre-filter also). When your plugs maintain a tan/brown color then your
mixture should be fine. Banshees gobble fuel, get a bigger tank for longer
jaunts or find some old-fashioned friend with a utility quad to carry extra
gas for you.

assume you haven't changed the jetting, have you? Have you recently
messed with the carbs, maybe cleaned them or something, and when you
put everything back together it no longer idled?
I had a similar problem with mine. (2000, engine is stock) The
throttle cable seemed to be sticking (happened more than once, enough
reason for me to take it apart and clean everything out. Still
happens though....makes me nervous.) Anyway, I took the carbs off,
cleaned off the slides, inpected them for scratches, gouges, etc...
found nothing. Put everyhing back together, and now she wouldn't
idle. Ran fine at 1/2 to WOT. I was mistified. Had several
knowledgable (Not Banshee experts...just mechanic type people) friends
look at it, no one was sure what the problem was. Then I ordered a
service manual and saw the problem. The slides had some how been
turned around, and ended up in the wrong carbs.
If you notice on the slides, there is a notch out of them on one side.
(Not the notch that guides the slide, this is more of a notch off the
bottom of the slide.) Well, according to the manual this notch is used
at idle... Without it, it starves for air and dies. Once I switched
them back around, she ran great! Still does to this day.
I felt stupid making such a simple mistake, but I just chalked it up
to experience. After all, I fix computers for a living, not quads.
Quads are for fun.
I hope this helps.
btw....has anyone else had problems with the throttle sticking for no
apparent reason on their Banshee? It doesn't happen very often, but
when it does, its quite nerve racking. It seems to be independent of
the weather. (ie.. water is not freezing in the throttle cable.) I
have checked all the obvious stuff. Cable isn't kinked, I lubed the
cable, checked the carbs and slides for scratches, nicks, gouges,
etc... Nothing. Everything seems normal.

on bansheehq.com - a Banshee only gets about 30 - 35 mile on a tank
