Hi can I ask for help I’ve built a hardtail chop using an old xs650 1979 I found the engine and carbs are all in bike now , I’m trying to tune it but having trouble it seems to get hot quickly, slightly spitting back through exhausts too on closer inspection it has mikuni 34 carbs but 150 main jets and 130 pilot air jets in it it’s running after market exhaust and cone air filters, your help would be appreciated and thanks in advance
