Starting ain't easy

Recommended Posts

Hi guys,

I got a problem with my CRF 250 '04.

I only use it for enduro's (3 hr race).

Problem is, if I'm riding & i stall it I have difficulty getting it into nautral.

And starting it afterwards can take up 15 kicks (i use the the hot start).

It dosen't start that well cold either!

If the bike is hot & i'm not moving, put it in nautral & press the kill switch. It starts first or second kick...

I'm sure the stalling of it is partly me but there must be something else too.

I've had a new piston, plug, valves (S/S) gaskets & seals all done.

Any ideas?

When the bike is hot put it in neutral- they don't like to start in gear.

Slowly cycle the kick start until you hear the click from the decompression lever. Then give it a slow firm kick. If you are real hot use the hot start. Make sure you are jetted right. Remember she's not a 2 stroke.

check your jetting and valves. Mine always starts in 3 kicks or less, hot or cold.

I would check valves, cause my bike will start first or second kick easily once warm, and cold maybe 3-4 at the most unless it is extremely cold or has been sitting for a long time.

Read the owners manual.

It tells you how to start the bike.

If you stall it in gear around a turn........you have basically flooded the engine. You have to use that procedure ( one for starting flooded engine), and then it should start right up.

see ya

The jet options,

what is best for the bike, there is 2 isn't there?

Do I check valve clearance to the book?

Does anybody else have trouble finding nautral?

I know you can a better 'black box' (behind the front number plate) it's ment to give a better spark, do they really work?

Thanks for the comments.

I'm at sea level , and just went with a 142 Pilot Jet( to help with starting) , and left the rest alone.

The 250F uses the basically the same clutch plates as the cr125 , and if they get slightly warped....you will not start the bike in gear. ( Found this out after I put in a new clutch ) . Started in any gear .

I bought the bike used ( January 2005) .

Straight from the owners manual :

Starting the engine excessively charged with fuel by throttle blipping or other reasons.

1. shift transmission to neutral

2. Open throttle fully ,repeat kickstarter operation 5-10 times , slowly to discharge excess fuel from engine.

3. Pull hot start lever and kick start the engine ( do not open throttle).

4.As soon as engine starts release hot start lever .

see ya
