rattle sound
-
hello guys! The bike is making a rattle noise on low rpm and I have looked around a bit and it seems it is not that unusual? A new cylinder is on the way but will probably not be mounted until next season. What do you guys think? A serious problem?

@irongamer727 could be something as simple as loose rivets in your exhaust
-
That or small end rattling worse case

@irongamer727
sound to me like powervalve, mine used to do this, bushes get a bit worn and they rattle , or piston is hitting it and it rattles, either way take cover of pv and feel the end will soon know
-
the powervalve is open and not hooked up. dont think it is in contact with the piston as it has been sounding like this for a couple of 1000 kilomiters. dont you guys think it might be a worn piston? the snorkel is ON

@irongamer727 Ahh if the PV is pinned that would explain why I thought the snorkel was out.

Ye. Previous owner managed to f*ck up the port somehow. Running great without but the sound worries me. Need this cylinder to last the season out.

@irongamer727 Literally mitaka piston is £40 plus gaskets £20 and an hour job to replace.
There isn't really an excuse for two strokes to fail.
It's either the piston fails and costs you a full rebuild, or you spend £60 and replace the top end making it good for another 10k miles.
If it is even the top end that's the problem.
Either way, you're putting your life in the hands of a machine you don't feel comfortable in. If the machine fails, you have the risk of taking not only your life, but those around.
For the sake of strippng the cylinder down for a quick gander, it hardly seems worth the hassle of it failing.
That's my two cents anyway. I would always be overly cautious.

How big is the chance that a dt engine with 24000 km on it has failed connecting rod bearings? Anyone experienced that?
-
Entirely possible
Depends on use and abuse tbh
-
Does that sound have any similarity with that?
-
Sorry I'm on holiday in France at moment miles from any wifi

Spoke to a yamaha dealer today. He said not to worry and that it most likely is the powervalve vibrating a bit.
