    I've got a bit of a rattle on my TE 250 engine. Not attempted to find out where it's coming from yet, but will be having a look around the engine later. It's a light rattling noise, not very noisy and not sounding horrible. Runs fine (apart from the intermittent stall issue, which was already happening from time to time before), smooth, plenty of power. Doesn't seem to be related to clutch position / gears, present when stood and running in neutral and when moving in gear and when coasting.

    What is there that is worth checking?

    Are you positive it is from motor. My 09 te310 had rattle noise from rear disc rotor and s/a in muffler.

    I'll have to get it on a stand later and have a look more closely, it's still there when stationary so brake seems unlikely, but could be exhaust.

    Do not rule out rear disc, it is a floating rotor and gets play over time.

    Took out the plug to check if this had anything to do with the engine dying when idling (intermittent). Plenty of crud in the plug hole, cleaned it out, plug fine so refitted when cool. Started up cool and no noise at all now.

    Even when I could hear the noise, using a screwdriver, the internals all sounded really smooth.

    Worse when hot? Could be chain, fine now cooled down again.

    the stock auto cam chain tensioner is a ratcheting type device. sometimes these fail and allow the cam chain to get loose and slaps around while running. this sounds like a rattle or slapping noise coming from the top end

    More ticking. Tick-tick-gap. Twice a second(ish) at 1900 (ish) revs. Losten to the engine with a screwdriver amd all sounds smooth. The ticking audible outside. Disappeared now it's cooled.

    Edit: So the cycle is tick -tick every 15 (ish) revs.

    While rooting around looking for possible noise sources, the bottom left hose was touching the exhaust header, so I've fitted the right part now which is shorter and bendier, so has a decent clearance.

    This evening, I took out the tensioner and it's only in about 4 clicks. Put it back and pushed an allen key in where the spring goes and it was tight. Ran it, took out again and it came out in the same place, so not slipping back.

    Got the rocker cover off. Found 1 x stripped thread for the cover screw, front right. Not pulling the engine to coil it so it will have to seep a bit if that's what happens. Chain has a nice tension. No play in the cam bearings. Valve clearances all good.

    Put it all back together again.

    Re-epoxying one of the front threaded inserts for the tank panels now, so going to let that set before re-fitting and firing up again tomorrow.

    Fired straight up, it always starts well. Still a tick tick noise though. Needed a MoT (annual test), so I rode it down today, about 10 miles. Sounded horrible when I got there. Test was fine, rode home slowly. Engine out time.

    Cam bearings are gone, 1 really bad and 2 a bit loose. It went from a ticking noise to really noisy in about 30 miles. Limped home another 10 miles very slowly and it held together. Some swark in the cam boc and a bit in the LHS screen. Sump had a bit of debris on it, but not too much.

    Well done on finding the issue before it did more damage.
