Default Ttr225
Got a 2000 TTR225 that's been giving me a ton of problems. Few years ago, the battery wouldn't hold a charge. Now, it's running like crap. It runs better every time I take it into get a carb clean, but I've been getting carb cleanings as often as I take a piss. It's costing way too much, and I can't figure out for the life of me how to remove my carb. Usually it wouldn't start, but once it had the carb cleaned it was fine.

Now, it'll start up with the choke out but I can't ride it until I let it warm it up after a long time probably 10 mins at the least. For the first 5 minutes, it'll begin to cut off when I give it gas. After the first 5 minutes, I can ride it but the ride is jerky as hell. I can hold the throttle at constantly, but the power will surge whenever the hell it wants.

I'll try to get a vid of it up this weekend... but any ideas as to what's causing this? I'm going to drain the tank and carb this weekend and fill it with SeaFoam then let it sit for a night. Drain it all out and put the gas in. Think it'll help?

Thanks in advanced guys.

You are letting gas sit in the carb too long and it's clogting up the jets. You need to clean it or have it cleaned. When you are done riding it turn the gas off and run the gas out of the carb. You should really try to start it every couple of weeks to prevent it from happening.The carb is pretty easy to remove and clean. I've never worked on the TTR but most bike are the same. There is a clamp on the air box side and the cylinder side. The throttle cable goes through the top of the Carb, which should unscrew revealing the slide. Once you loosen the clamps and remove the slide you can remove the Carb. From looking at pics you probably have to remone the seat and gas tank to get enough room to work. Hope that helps some. I usually clean my carbs with brake cleaner and some new gas.

Thanks man. I'm actually running the bike every week for a good 20-30 minutes. I'm just going to start draining the carb every time at this point. This must be my 10th carb cleaning in a year.

I have tried to get the carb off, and I can see it's just a few hoses and clamps but I'm afraid I'll screw it up.

Just remember how everything goes together and put it back the exact same way. Bikes are really easy to work on...if I can do it anyone can!!

Do you think the SeaFoam will do anything?

I've never used it but it seems like a motor/carb cleaner. That will help loosen up all the buildup in the Carb.

Been meaning to update yest but didn't have a chance. Just something to say about SeaFoam... that stuff is MAGIC. It didn't fix my issue completely, but I put some in the carb and let it burn off and I could immediately tell that it was running better. Less "jerk" when I give it throttle now. Also, idles a lot better. I'd recommend using SeaFoam every tank just to avoid having the carb issue. Great stuff.
