Bike idles high and dies if EV off

Hello all,


First time caller here. I just bought a 2005 Rebel 250. 13k miles. I bought it private party last week. They had it for 3 years in the garage with a total of 50 miles put on it. They bought it used at a "shop". I road it home and it seemed okay. After about 50 miles put on it, the idle started to race, even with clutch disengaged. I noticed the Enrichment lever on the left handlebar was 3/4 of the way toward me, which is I assume means the choke is almost fully on? There doesnt seem to be any writing that actually tells me if toward or away from me is when increases or decreases the mixture. Is all the way away from me off?


Even after the bike is warm it seems to idle high and will die if I dont have the choke/EV on at least somewhat. Since the problem I have changed the oil, installed a fuel filter, changed the air filter, changed spark plugs, drained the old fuel and replaced with ethanol free fuel. I have not removed and cleaned the carbs yet. As this problem seems somewhat specific, I hoped someone on here may have run into this very issue.


Also I sprayed WD-40 around the boot from carb to AF housing and didnt notice any changes to idle. I havent removed and cleaned the carb (which I am willing to do), but wanted to see if cleaning the carbs is chasing ghosts or is there a common issue that could cause this? Thank you for reading.

When the enricher is away from you it is off. If it's moving forward on it's own it may be because the cable is pinched somewhere, and when you turn the handle bars it will move.

Before I go into a carb cleaning, I would use a heavy handed dose of Seafoam for a tank of gas and see where it goes.

Thanks Guba,


The enricher isnt moving on its own, sorry if thats the impression I gave. I just have to be over 1/2 open for the bike to run. You think seafoam in the tank might break something loose in there? Does that mean you do think probable carb buildup?

If the bike sat idle for a long while it has a good chance the the gas has varnished the carb.

Please don't post two threads/posts on the same subject. It's confusing and unneccessary. I've deleted your other thread.

Keepin' all the left over parts. Gonna use 'em to build another bike!

My mistake, wasnt sure which section the issue would be related to, so I posted twice. Wasnt trying to ruffle any feathers, just hoping for good folks with a similar experience.

Just a little explanation of forum protocol.

I'm thinking like Guba; with gas in the carb that long, you're gonna need to clean it. Lots of info on that subject here as it's the number one problem with bikes that have sat with fuel in the carb. If you have access to an ultrasonic cleaner, they do a good job of cleaning a carb in relatively little time.

Thanks guys, I guess that is a logical step anyway since I have changed the other things.



Big_J's post from 2009 shows how to break down and put back together the carb, but he states in bold that it does not cover complete disassembly for cleaning. Is there a post that does show disassembly and cleaning?



Is best practice to take apart as much as possible and soak everything minus the rubber parts?


Thanks again for taking the time to help a new guy.

My 125 idles normally when itís cold. If I drive for a while and stop, it will idle high. My guess is around 1500 RPM.
Itís a low milage bike, 5000 KM when I bought it. 1998 model. Previous owner says he cleaned the carb. I have driven it some 600 km since I bought it.
Any ideas?
I have bought a CG 125 carb off Ebay. Will try a swap to see if it helps.

BTW, what oil should I use for this bike? Is synthetic oil OK?

I know it's a long thread, but if you read it, it discusses various cleaning methods. https://www.hondarebelforum.com/f39/...y-1743-26.html

Yes. Soaking isn't as fast or effective as using an ultrasonic cleaner, but will (eventually) get it done.
