**babyblade250rr** · 1st July 2007, 11:58

Hi all,

I'm sure you wise people can help me on this matter,
My 94 cbr250rr has a little problem she has started to inconsistantly idle normal idle seems to be 1.5k rpm then it sometimes lowers 1k rpm then back up again when i hold the revs in neutral at say 3-4k rpm then drop the throttle she stalls?

can someone please help me with this

cheers

Fuelling, carbs or (possibly) spark plugs.

Just sit back with a beer and watch TV when things need doing.

Oh, you wanted bike advice, not advice on how to be idle.

Never mind then.

Is it due for a service or does it ever see a bike shop???

Could be carbs, carb rubbers, valve clearances, plugs, air filters or a few things really but without knowing the bikes history it's a bit tricky... A 250cc / 4 sports bike is a finicky thing that needs regular maintaining I'm afraid..

thanks guys notice also it's got this little popping sound when held a 5k rpm in neutral which leads me to believe it could be a spark plug or lead so will book into the bike shop for a check up tomorrow

cheers

Good advice once i found out it was something that i needed to send it to the bike shop for i did grab a beer and sit idle haha, so got two points of good advice today

Every CBR250 I've come across idles inconsistently in a pattern.

As for the stalling thing, Fire your bike up with the choke and no throttle, let it sit for a minute before you turn off the choke and start riding. It should not stall if the engine has been running for a while, otherwise you have a problem and it really isn't just u.

On my bike if the temp is below say... C__|__________H it will stall.

thanks, but i also find that after riding for a while also when bike is heated right up and i might be slowing down for light or something pull the clutch and she stalls there too.

another issue i've noticed is it has a strong fuel smell very lean smelling perhaps this is part of the problem

well team,

Just got back from the boys at red baron found out a few interesting things might be useful for those that come across the same issue.

apparently city riding on a cibby is not enough to heat the motor right up therefore causing the carbs to load up causing a stall.

Riding a cibby on the motorway in 6th gear at 100km/h sits at 9k/rpm which also isn't enough to get the cibby rolling therefore loads ups the carbs and causes a stall.

Apparently they like to be thrased alot!!! being a high performance 250 they run very lean and air fuel mixture is optimum at ridiculously high revs.

So went out for a cane to muriwai beach whilst the weather held up and what do you know? she was happy!!!

the moral of the story is a babyblade is only happy when you are (14-18k/rpm

thanks again for all your input team

My god you didn't just buy that from Red Baron on Gt North Rd did you? The red, black & graphite 250 fireblade with 30,000kms for 6.5k???

I was going to buy that bike, but I was told fuck that buy a 2007 ninja with 0kms and a warranty for 7k at Mt Eden..

But good on you, I would have loved that, Personally I think it's the coolest 250 around I wish they were still in production.

Regardless of the experience you've had, and the fact that it aligns with what they tolds you, I still have to call bullshit on what RB have told you. I've friends that have had these, and that's not the experience they've had. That's the sort of advice that would apply to a 2 stroke.

I know you will anyway, but make sure you keep an eye on it, they're typically sewing machine reliable, if you know what I mean?

**Crowdog** · 2nd July 2007, 20:42

If you havent ridin anything faster than a cbr250 then they feel like a pocket rocket if you have then they feel like an electric scooter still heaps of fun in the twisty bits though

**FROSTY:Me** · 2nd July 2007, 21:08

Baby Blade--I'd suggest to ya that you diddn't quite hear it right.
The problemis a combination of long time sitting at idle and relatively short trips.You could just as easily (but a lot less fun) fix your problem by riding ya bike in the lower gears -high rpm down the motorway for 10 minutes or so.
