CRF's Only Forums

Hay guys i am getting a CRF 250r 06r in a couple of days and i have been told that the 250r's are a bich to start sometimes, i was wondering if somone could tell wat the best way is to start it

I also herd that to much throttle will flood it.[/b]

turn fuel on
pull out choke
3 twists of the throttle
and kick till it starts
and don't give it throttle when your kicking

and don't give it throttle when your kicking

EVER.
That three twists of the throttle is only for when the bike has been sitting for awhile and is stone cold.
I hope you have had someone who really knows what they are doing, I mean REALLY knows what they are doing, look that bike over.
If the owners are who dropped in "these can be tough to start" look out. That sounds like a set-up.
Why ? Because they are at their worst to start when they need a valve job. Buyer beware. Doug

thanks guys for replying!!!

Is there any other ways to start the bike if it;s been sitting in the sheed for a few weeks


(Fresh fuel in the CARBY allways helps right?)

yer fresh fuel and at the bottom of the carby there's a large bolt that when taken out will remove the left over/old fuel out of the carby

Like Mark said drain the float bowl.
Ideally drain it after cleaning the bike/parking it for awhile,every time.
If you kick and kick the bike and it doesnt start, and further it doesnt flood after all that kicking the problem is easy to diagnose. You're not getting fuel.
So, remove the pilot jet and clean the daylights out of it.
Now this older bike, if it's still hard to start the answer most likely is again simple : You have zero/too little clearance for your intake valve or valves and you need a valve job. Read about how to check them or pay someone who knows what they are doing to do the job.
If zero'd you can probably shim to spec, but know you'll only get a ride or two and the same thing will occur.
Do not cut corners on the valve job. Use ~, they can do it for a great price with great quality.
If not done right you are wasting money like you wouldn't believe and will regret it.
If despite these grave warnings you insist on having a 'friend' etc. do the job know this: If they tell you the valve seats "look okay", the guides "look okay", etc.,etc. you are dealing with the clueless.
If someone hears these things and proceed anyway they deserve the outcome they begged for. It'll be ugly. Doug
