2001 cr 250 won't idle with kehein pwk carb

[rmzrider21]

I bought a 2001 cr250 recently and put a new top end on her. cylinder piston rings etc also new reeds . now she won't idle need help.!!

[mynewcr250]

i remember you posting this up a while ago. what is:

1) your average temperature

2) your elevation

3) your current jetting and air screw placement

4) your current float level

[rmzrider21]

jetting is 180 mj 48 pj and air screw 2turns out needle at 3 clips and elevation 2000 with 60-80°F

[mynewcr250]

stock reeds?

[KcDavis]

I am assuming you tried adjusting the idle?

[mynewcr250]

if you have stock reeds try 42pj, needle on 2, 172 main. start with the air screw at 1.5 turns out. it should idle using that PJ, and the needle and main are good at sea level here so it should be a little rich at 2k feet and leave room for you to adjust from there.

boyesen rad reeds are in it.

Why do you want your bike to idle? To foul plugs?

2 stroke bikes really dont like to idle.

BS

ok, the boyesen will like a richer pilot and usually a leaner main, even so, at your altitude id start with a 42pj and airscrew at 1.5 and see if she'll idle on her own.

2 stroke bikes really dont like to idle.

My 2 stroke idles like a 4 stroke all day and never fouls plugs. This is a myth fabricated by people trying to screw buyers into buying their clapped out pieces of crap by telling them that the reason it runs like crap is because "2 strokes are not meant to idle".

One more thing, I watched a race from 03 with Ricky Carmichael and at the end of it he pulled off the track to pick up his mechanic in the pit area and his 2 stroke sat and idled like a 4 stroke. Any well tuned bike will idle 2 stroke or 4 stroke.

What jets do you Honda people typically run with a Keihin? KX's are normally 45/48; 158/160. Just curious, 180 seems fat.

My 2 stroke dont idle because when im trail riding, if i come off the bike i want the back wheel stopped if i happen to fall into it.

Have seen fingers almost lost because a bikes engine kept goin when his hands went in.

I have seen mx boots literally grinded to the ankle bone of another person. He still walks funny.

I have a couple of things i like about my bike not idling(it will if i want it to)

What advantages does having it idling do? NONE

Ok, saying that you jetted your 2 stroke so it wouldn't idle for safety reasons and saying that a 2 stroke "isn't meant to idle so it won't foul a plug" is a completely different statement.

[KcDavis]

My CR 250 idles all day. Going on 3.5 years of owning the bike and haven't fouled the plug yet.

[mynewcr250]

Well looks like everyone shit all over your thread with more useless 2 strokes should/shouldn't idle opinions.

Pm me, ill try and get you sorted.
