Yes, I did a valve job not long after I bought it. The other day I pulled the valve cover, inspected the valves, and added a little gasket seal around the edges of the cover. Still leaks, but I need to take more body parts off to really see in there, but it seems it was near the head. My buddy has one of these, and it worked really well. I think I'll pick one up:  They are $5.99 at Harbor Freight, and would come in handy around the garage. I'm off to get some oil, and take a closer look at things. Maybe try to get a good video of the noise to post here. In the end, I may end up needing to do a rebuild...just like the other post titled Matrix rebuild. Jon |

Check the exhaust pipe bolts that hold it to the engine. Our Xingyue XY150T lost one and it then made a clatter noise. You had me hoping for an easy fix, but no luck there. Both nuts are there, and appears solid. Thanks. |

I think it is internal. The more I listen to it, it sounds more like a knock than a clatter. I took off the variator completely, and same sound. Then I removed the cover that is over the fan on the other side, but same noise. I thought I'd drain the oil and look for metal shavings, but didn't find any?? Nothing at all in the filter?? Hmm? Not the clutch, variator, or fan. I did develop an oil leak too, but not sure where. Any ideas? I'm rather disappointed right now. I was hoping for something simple.  Thanks, Jon |

Interesting info. It could be coming from the other side too?
Its a rain day today, so I'll be in the garage and hopefully get some info.

Thanks Rich, you can delete the other post now.
The scooter drives and sounds great, but the clatter seems to happen at anything above idle.
I had trouble getting the belt off, and wanted to ride so I put the CVT cover back on. I'll check it out again soon and post back here on my findings.
Thanks,
Jon

This might be hard to explain, but I'll try. (I'm new to scooters). It is a Rakatak MD 150T-6 (2006). JMStar is on the label too.
I just noticed this rattle. I'm not sure if it is coming from the variator or the clutch. It doesn't matter if if it is at idle or revved up under load.
My next step is to take off the belt and start it to try to isolate where the sound is coming from.
I'll get a better idea of where it is coming from later, but thought I'd start a thread in case it is something obvious.
(On a side note, coincidence? I'm missing a screw right in front of the CVT cover near that boot, and sounds like something is rattling around there).
Thanks,
Jon
