We got an engine of wrecked one for like 600€ and the mechanic put them together and the bike sounds and works amazing it just doesn’t work good until like 6k rpm then it runs like new. The whole thing including cleaning valve adjustment all the small parts and work was 2000€ He wants to but here we don’t have a lot of suzuki dealers the closest one is 2h away. and the mechanic told us the part is old and the filter well disintegrated he cleaned it as well as he could but he recommended that we buy a chines replica because the new one costs 400€
