Hi this is my first post. I got a 2003 CR250 when I was 14 the year it came out. I rode the bike constantly for 4 years did some Deseret races and motocross races. Long story short I have only riden the bike once in the last 10 years. The suspension has leaking forks and the rear shock bottoms out and on every bump. I live in New York and will be going back to Arizona where I grew and want to ride.
I am planning on putting new fuilds, tires, chain/sprocket topend and maybe a bottom.
I loved the stock suspension when I was 14 lol, but I am probably 30 pounds heavier. I am 220 pounds. What should I do about the suspension? I don’t want to send it out or anything like that. What should I order? Also any other suggestions would be appreciated.
Here is a pic I put new plastic on the last time I rode

I have seen the wrench rabbit rebuild top and bottom kit. Have you had any experience with them? Looks like a great deal, but I have read it may lack quality. I remember using weisco back when I used to ride. Reading up lately and people have been drilling the piston because of the exhaust port, or somthing like that.
What brand would you rebuild with? Also what about the clucth. last time I rode 5 years ago it seemed fine, but I’m not sure what has ever been done to it, so probably time for some maintenance of some sort.
Thanks for all the advice
I always used Wiseco, I prefer forged. (Just let the bike warm up more slowly as forged expands quicker on start up.)
The clutch is good in this bike, I replaced the stocker with hinson after a few years, just check the basket and its bearing/bushing to make sure its free of grooves and play. I did burn up a lot of clutch plates, as Im a clutch abuser. Oem plates lasted longest, but I ran many Barnett kits with good results, I wasn't happy with one of the EBC kits, but who knows, probably was more my fault than the clutch kit.
If you plan to mx it the stock 48 is awful for normal mx tracks. If your riding is in wide open areas its fine. For mx it needs a 50, or 51 for really tight tracks. This also helps the soft bottom end power the CR is known for. This bike is great in the mid range, and not too shabby up top either. I currently have a YZ but I plan on putting an 02-07 back in the garage at some point, its a great bike.
The Shop
On the crank I'd only suggest running oem as well as all the gaskets for the engine rebuild. As mentioned the 13/50 gear ratio seems to be the sweet spot for the 02-04 stock engines. Honda went to a 13/48 combo on the 02-03 models after using a 13/50 for many years on prior models.
Agree about holding off on the Keihin carb swap as it's not really a must have in my experience. I tested with a 2000 38mm Keihin PWK A/S about 10 yrs. ago & ended up going back to the TMX mikuni.
Depending how bad of shape the sprocket is on the bike I’ll just keep what ever one is on there unless its really worn. I remember using both larger and smaller depending on riding type I was doing. I will only be able to ride it for a few days while home for a family reunion, so won’t be doing mx. If needed I’ll put a 48 given I will only be doing trail type riding.
I’ll have my friend/ mechanic look into the clutch and go from there.
I’ll check out the piston recommendation. I don’t really have a preference.
