how to uncork a 250x?

[KCT]

I am sure this has been asked before and explained before but can some one help point me to the best way to uncork my wife’s CRF250x? And is there a way to get rid of the annoying dead spot the bike has? It seems like when you give it gas it hesitates and then kicks in.

if its a new bike you want to let it break in before you really start wackin it on.

Is it a new bike?

Alot of people would suggest the Closed Course Competition Modifications

If it is a new bike, then you deffinatly want to break it in first. Then cut out the air box and pull the disfuser thingy out of the exhaust pipe. It may take a little tugging, pulling, and patience to get it out, but its way worth it.

sounds like a leak jet problem with the bog....every time i read the x's seem to come sloppily jetted (not trying to burn you x riders, the R's probably do the same thing)

My CA '04 250X has never had a terrible bog when at operating temp, even with stock jetting. The bike has the stock pipe with the diffuser in, but I cut the end off of it. I took the rubber cover off the airbox (snorkle) and cut the airbox open in that area. I went up to a 140 main, 42 pilot, and raised the needle a couple of positions. The bike runs great, at some of the elevations I ride it even seems a tad rich up top.

Are guys just snapping the throttle wide open from a low idle? There's a big difference between quickly opening the throttle and clumsily snapping it open. I get forward thrust equal to what I do with my right hand, the bike never stumbles unless I have been sitting and it's cooled off. Now, if the bike is cold it stumbles all over itself, but I normally let it run for a few minutes while I gear up.

I going to put a FMF Q pipe on and see how that does.

I had that low end bog at first, here is my cure:

Open up the top of the air box

removed backfire screen

JD kit; 158 main, red needle 5th clip position

42 slow jet

Zip ty screw out 2.25 turns

Result: no more bog, crisp response all the way up

I have read that opening up the stock exhaust doesn't make any more hp, just makes it louder.

I have about the same setup as above, but with a 160 main, and screw is probably 3 turns out. I've been running U4 and the bike is really happy. No bog, even when whacking the throttle open, but I usually don't do that anyway.

When stock, the bike did have a huge bog off idle, even when hot. You really had to be smooth with the throttle to avoid it. It is (was ) a CA model.

I took out the baffle in the pipe and found it to be too loud. My ears would ring at the end of a day of riding. I installed a FMF Q and now it's just right. 70 miles on Saturday and my ears are in good shape. This was with a 15 minute 60mph blast down a highway as well

Today I removed the pink wire and opend up the air box of my wifes bike. WOW what a difference. I am not going to make any other mods to this bike becouse it is perfect for her now. No bog no problems. Thanks for your suggestions and comments everyone.

I have no bog so far (knock on wood) and the bike has 90 miles on it. It does seem to stumble when cold though and takes a few minutes to warm up. I will consider opening up the airbox and rejetting when I start using all the power (not there yet). It also is difficult to find neutral on and I have been riding motorcycles for years. It may be loosening up as I am finding it a little easier now.

KCT-

What pink wire are refering to?

Do a search.

[HONDAMEC]

Where do you find this thing, in the baffle or spark arrestor?

[HONDAMEC]

Please let me know about the FMF Q, considering the same for my 49 state X.

[HONDAMEC]

What's the pink wire do and where is it?

[KCT]

on the Left side behind the air filter(remove the white number plate) there are some wires. there is one set of wires where there are 6 places but only 5 wires. snake out the pink wire and put it in the spot where the plugged hole is and put the plug in the pink wires spot. Makes a huge difference. I hope that made sence.

What the hell does the pink wire removal do?
