Lets get this off with my story. 99 banshee. Ran good except had an overheating problem, got a new radiator. Still overheated. So went through the head got a new gasket and got the head machined. Compression is good now and the bike is put back together. Well now we have a new problem. The bike takes much longer to start, backfires on the right pipe and makes a boggy noise when giving it gas. The throttle seems to stick a little now or to say it will keep a high rpm on the thing even when you release the throttle so anyhoot , does anyone by chance have an idea. If it helps the spark plugs where replaced when the head was put back together. Any help is much appreciated
