Default 2001 CR250 carb sucks

     

I tell ya,i just picked up the bike and right away i noticed how rich the thing runs.It has sludge comming out of the pipe where it goes into the motor.Is there an easy way to fix this?Also the thing just will not idle.Im going to go through it and clean everything up real good but has anybody had any luck with this carbs idle?I have a cr85 also and a blaster and the pwk carbs seem to be easer to adjust then this thing.What would be a good replacement carb?99cr250 carb?

Your bike came equipped with the cantankerous Mikuni TMX,
the only dud on an otherwise stellar motor.

A very good option would be to swap a Keihin PWK Air Styker.
The PWK was standard equipment on the 2000 CR250. You
could probably find a decent used one for under $50 or you
can buy a new one already jetted from Honda for $168.

Either way, you will find it much easier to set up, and your bike
will run like it is supposed to, for a change.

Thanks man.New to the whole 250 thing.Got the bike for 1800 and is in really good shape.Need to find out some info also on the power valve on how to clean it out a little.Could you just take the cover off and spray some carb cleaner in there or is there another easy way?Thanks again

No "easy way" to clean the power valve. Honda recommends you
decarbon the valve every 7.5 hours of use. Most people stretch
that to every 75 hours of use, if that often.

The first thing I would get is an owners manual and a service manual.
You can get both at: http://www.helminc.com

There is a nice detailed description on how to service and adjust the
power valve. One "tip" I can pass on, is to use oven cleaner to remove
the carbon buildup on the flap and sub-exhaust valves. Remove the
parts and place them in a tub and soak them with oven cleaner from
an aerosol can. Let stand for a couple of hours and wipe the carbon
off. Then clean any residue off with a solvent based cleaner and they
should look and perform like new.

You may be able to get that much if the buyer doesn't know they can get
a new one for $168 from Honda.
