Hi there, this has been concluded to be completely unrelated.
The engine simply reached end of life due to excessive use, 66k km done, no idea how many owners the bike had.
Engine Failure: Camshaft and Piston damage - Rebuild in progress
Hi all,
Hopefully Hello @Tamir as well, the one with the knowledge and kindness to reply the majority of threads!
My bike went in to mechanic for a new battery and fork seal maintenance as the right side was leaking.
Attached is the quote I got afterwards.
I noticed the black plastic (Can be seen on video, it's the black plastic round thing) is damaged, drove the bike home (5km) and there was a hard "klunk" sound on the front sprocket.
My Question:
1. Redacted*
2. What is the possible cause to this issue?
3. Is it possibly just a loose sprocket?
Thank you for the time you take to read and respond to my issue.
Exmoz greatly appreciates your input!

- Drove slowly home after the sound and there is a definite something gripping or slipping whilst the shaft is turning.
- Got stuck in second gear, after a kilometer or so my gears came loose again and was able to shift up to third and then back to 2nd and 1st. Now able to shift through them whilst testing parked.
- I parked the bike and left town for a week.
- Returned back to bike shop and showed them the attached video, they said bike needs to be loaded on trailer and brought in to shop.
- Removed the front sprocket guard and took video, all teeth seem fine no chips or breaks.

Your hypothesis makes sense. I bought a motorcycle that was neglected. When I bought it, it looked good, it drove well, but I knew I was buying a motorcycle that had been neglected.
Several years have passed since then, and since the
I'm still chasing a fault, I started with what was easy and cheap to fix, and today the problem still exists.
My problem: The engine has difficulty starting when cold. Below 25 degrees I starting it with a rotation of one degree in the throttle. I bought the motorcycle in the summer and I could feel this problem, then winter came...
Now I only have the major treatment left, apparently (because this measurement is not accurate), I have a compression drop when the engine is cold, and when the metals expand from the heat, everything works normally. There is no smoke from the exhaust and no other evidence of oil leaking into the engine, but that is currently the main suspicion I still have: a compression drop.
My motorcycle has already traveled over 70,000 km, and the engine works smoothly and beautifully, except for the problem I mentioned.
I think I received the motorcycle after an event of overheating as a result of an oil leak from the coolant pump oil seal. A 250 engine that working at high rpm doesn't have much to do to destroy it, 70,000 km is very respectable. Maybe I did treatment to the upper engine, to improve the compression? But maybe not! Why to touch it as long as there is no oil leakage. Nothing will happen if at low temperatures my engine is starting with the addition of a tiny turn in the throttle
