OK quick history. Washed the bike and it started running rough. Ended up changing plug wires and went to iridium plugs. Still had popping and backfiring under acceleration. In the mean time, changed the oil and overtightened the drain plug, so I replaced the front cover and left out one of the sleeves and O rings, so I had no oil pressure. Got a new gasket, repl front cover again yesterday, spun the motor with no plugs and had oil pressure, so I put it all back together and went for a quick ride. It has no missing or popping, plenty of oil pressure, but is very under powered. It revs up smooth but just doesn't have the power it did. I have not touched the carbs (yet). Someone mentioned in another thread that when you have problems, it usually relates to something you just did, so that is why I mentioned all of the above. Any ideas from the experts? It felt good to finally ride again, but I really want to get this thing back to it's former glory!!!!! Thanx in advance for your help.
