Hi everyone, this is my first post here.
I recently bought a 2023 primavera 50. I decided I wanted a bit more torque for riding 2-up, so I pulled the trigger on a malossi 80cc kit with the matching ECU.
The install wasn't too difficult except I had some difficulty getting the piston at TDC. I don't understand why it was off because I marked the cam sprocket and chain before disassembling the head. Eventually I was able to get the piston at TDC. The mark I made on the chain was about 4 links off even though the the arrow was lined up initially.
After I buttoned eveything up, I did the TPS programming. Unfotunately, the service engine light is now on. After seeing this I did more searching online and found out that the malossi euro 5 ECUs are not updated for the 2023 MY.
I am beginning to regret the cylinder install+ECU. The power isn't much more and the serivce engine light on is a disappointment.
Now the questions:
Is it normal for the exhaust to stink right after intalling the malossi kit?
It smells the burning plastic.
Does anyone have any solutions for clearing the engine service light?
The bike is idling just fine but the power just isn't there. I can't help think I did something wrong during the install. I should also mention that I switched back the original ECU and the service light turned off almost immediately.
Hopefully someone can ease my mind about my messing up my 13km engine.
