When a motorcycle spits flames while downshifting, it is usually due to unburnt fuel igniting in the exhaust system. This can happen when the engine is running rich, meaning there is an excess of fuel in the air-fuel mixture. When you downshift, the sudden increase in RPM can cause the unburnt fuel to ignite in the hot exhaust system, resulting in flames shooting out of the exhaust. It can also be a result of aftermarket modifications to the exhaust system or fuel mapping, which can lead to a richer fuel mixture and increased likelihood of flame spitting. **

There are several potential reasons why your Rieju MRT may be revving so high. One possibility is that there could be an issue with the throttle cable or throttle body, causing it to stick in the open position. Another potential cause could be a problem with the carburetor, such as a clogged jet or incorrect adjustment. Additionally, a vacuum leak or air intake issue could also lead to high revving. It's best to have a professional mechanic inspect and diagnose the issue to determine the exact cause and make the necessary repairs. **

However, it's important to consider the impact of these modifications on the bike's performance and handling. Always consult with a professional mechanic or motorcycle customization expert before making any significant changes to your Rieju. **
