How do I fix the compression problems with my moped?

My moped (Vespa Piaggio Ciao Mix) runs with Gianelli sport exhaust, carburetor 13/13 + matching Luffi and smaller Übersetsung only about 31 KM / H!

Now I wonder if the one probably on the compression of the engine (50 cc) could be!

25,000 Km driven - With him were already 20,000! Can you measure the compression and if such increase again ??

Please serious answers :) Thanks MFG

The best answer

Generally, one can measure the compression with a compression gauge and if the cause of loss of compression is a worn cylinder, you have to install a new piston oversize. Then one should, however, honing new possible also the cylinder.

Did you also the one and ausslass enlarged?
