Hey guys I've been out of the quad game for a few years and have some questions. I just picked up an 06 LTR previous owner said it has a full YOSI system on it with the stock heat shield on the header. Is that possible on the LTR? Also if its not a yoshi header how hard is it to add one or find just the header? It also came with a power commander and im curious if anyone knows how to adjust it or know what setting its on? It lights up etc but seems like there is a bobble in the throttle response which is uncharacteristic of the LTR's I have ridden before they are always so snappy this one seems studder a bit? It came with a full rebuilt motor and Dyno sheet as well showing 48HP ...? Does that seem right ? Thanks in advance !!
