2004 CRF 250r racing readyness?
Posted 09 April 2012 - 07:52 AM
I have a White Brothers Pipe on it and used it for 5 years.

Most people are buying a whole new piston kit each year, cleaning the piston really does nothing at all.
Have you ever changed you're oil and air filter ?

I personally have a 04 crf250r and race it. The bike is race ready off the showroom floor. You would just need to have the suspension set for your weight. But in your case I am honestly surprised the bike is still running if that s all the maintainence you have done.

Like the above post said cleaning your piston does not do anything...Im sure after all this time and only dune riding that you are farely close to some sort of failure. At the very least I would get a shop manual and start checking on everything. Pull the valve cover check your valves....it's gotta be hard to start? Your valves are probably tight, probably need a piston and would venture to say a new bottom end too. I would get the head rebuilt by a local builder or send it to crfsonly or a reputable place.....check your cylinder for any scoring...if its good and you can still see hone marks then you can scotchbrite it.....buy a Pro-X "B" piston and a new OEM crank assembly. Get new bearing for your bottom end....and take it somewhere to be dissassembled and re-assembled correctly with the new crank piston and head.
Or just keep riding it and one day it will make really bad noises and lock up on you...hopefully close to camp....and then you will have to do everything I said above plus replace anything else that got damaged....

I race my 05. Its a fun bike. But like I said above you should get into maintenance especially if you plan on racing. You can still be competitive on that bike especially since you will be Beginner/Novice class. I'm in Novice now and have no problem catching some of the guys on the 450 novice line in front of me....its the rider not the bike.

Read again what was posted.
Yes the sand kills the bikes' engine. If you rode a bike with a fresh motor you would see just how down on power yours is.
I can break your bike with a new motor in 20 hours ride time as a track bike.
Sounds like you think your riding it hard, but have no clue.
"whole transmission system" "carbs and pistons cleaned out" man that's funny!
Your bike has 1 carb and 1 piston.
Sorry dude but you asked for it.
You need to stop going to Glamis. Your in SoCal where some of the best tracks are. You need to meet a new group of friends that you can learn from.

I don't think him going to a track would be a good idea, i certainly wouldn't be riding a bike that has been poorly maintained like that.
Sounds like the engine is about to explode !

My thoughts exactly....I have some friends who think riding their Banshee at El Mirage is hard and intense....it's all a perspective thing..
My suggestion is that since you "check" the transmission system(you split cases after every ride??) you should be mechanically inclined to do a full rebuild. If you aren't then I would take the motor to someone who know what they are doing...if you are in SOCAL their are alot of good builder here. Then go to the track for a eye opening experience.
OR you could go to the track before re-doing the bike....racetown/GlenHelen/Comp Edge/Perris etc....and take a few laps around the Vet track first then get on the main and ride it...you will know immediatley that you need to rebuild the bike.

in my mind to race this, it's too much of an attention whore for my liking. i can handle pulling a piston and rings and honing every few races and fork oil etc but once you throw head work and shit on there it goes way out of my pricerange..
to answer your question though your bike is easy raceable, just give it some love... the clutch has a bit of a short throw for me but it's not worth my time to fix it
