Hi I discovered recently with my uncle ne honda mb5 in the roof floor and ripped it right under the nail. She has a 5speed circuit, 49 ccm ca 3ps and runs after carburettor cleaning just 40 km/h. Exhaust msu I still emit, but I don’t think that helps much. Who knows what you can do, that she is running 60? Ritzel I have already tried, but does not get a good effect. Please answer me, but shouldn’t be so expensive! Mfg, domi
