Just got by bike back. Took it in for a rear tire and change the fluids. Then decided to have him check the cam chain tension-er since it has 34000 miles 99 fltri. He said the inside had a piece broke, so I told him to replace them he recommended just replacing them not the upgrade.Went to pick it up today and the mechanic said he cant get it to run right. Very rough at idle hard starting and not a lot of power like it had. He said it was put together correct that it must be my tuning was off and he did not know how to tune a power commander. Took it home put it on my laptop reinstalled the the map. No change. Motor also seems noisier than in did and has lifter noise or something on top ? Motor has a Big bore Kit head work 10:1 tw-55 cams with decompression buttons.Don't what to do next ? Top end out of adjustment or cams were not installed correctly ?
