Question 03 225 died on me tonight

I tried searching but no dice.

I've got an 03 with 7300 known miles on it. Tonight while heading into work and I started hearing a ticking noise and the bike shut down, upon investigation I found the cam chain tensioner bolt backed way out.

Any help would be appreciated.

I'm no expert, but....It sounds like your timing chain may have jumped a tooth and possibly (likely I think) a valve hit the piston. When a valve hits the piston it bends the valve at the least, it can also crack the piston and/or crack the valve guide, and in extreme cases even ruin the head.

As I said "I'm no expert". You might be lucky and the engine is not damaged, but just "out of time" because the timing chain jumped a tooth (or a few teeth). Some pistons don't hit the valves. I think that depends on the valve/piston clearance (it's tighter in hi-compression engines) and also it depends on the location of the piston & valve during the cycle of the stroke. (One valve is more prone to contact with the piston, because of the direction of the cycle. Half the time the piston is moving towards the valves, and half the time it's moving away from them.)

Hopefully, nothing got damaged.

If I remember correctly the large cam tensioner bolt only covers the hole where you stick a flat head to hold the tensioner. You may have to look further for the answer to your problems.

I once had the engine apart and forgot to torque the cam sprocket bolt. It made it about 10 miles before it loosened, bent a valve, and needed more work. A new valve solved my problems.

Does the Clarke tank bolt right up with no mods?

Pretty much. You do lose the plastic wing/grille things on the stock tank, but the Clarke tank takes up that space. You have to put some more foam over the top frame tube, but it comes with the tank. I have 2, one blue and one black. Using the blue one, but keeping the other. I've had 2 stock Honda XR plastic tanks destroyed by ethanol. Hope this doesn't happen to the Clarke tank.

Mine is pushed into the box so it's not sealed anymore. I tried to take it all apart to fix it, but it just opened up a whole can of worms.

I'd replace the part. It probably wouldn't cost much. Riding in a desert I'd be especially concerned about the air filter being perfect & maintained very often. Sand is silica, and is very abrasive in an engine.

Well, heres my '02 XT225 project. I spent alot of time lurking and learning before this purchase, and i thank you all for the info!

Looking forward to many great adventures with this little machine :).
