Peace, mercy, and blessings of God be upon you. I have a butterfly motorcycle that has been converted. It's Japanese in terms of decorations and appearance. As for the engine and gearbox, ماشاءالله تبارك الرحمن (Masha'Allah Tabarak Allah - God has willed it, blessed be His name), they are guaranteed. The motorcycle is active and strong. We can ride two people on it, and it goes on nice rides. I just had it serviced at the dealer. I changed the filter, spark plugs, spark plug wires, relays, starter, starter brushes, tightened its chain, and adjusted it from the back and front. The invoices are available. The motorcycle needs gearbox gears; I haven't had time to do it. The motorcycle has 5 gears: 1.2.3.N.R. The motorcycle is currently stuck in third gear and only needs gears. The sale is urgent. The motorcycle turned off and won't start; I don't know what it needs.
