Tuned up bike over weekend with screaming platinum plugs and wires,seems to be a noticeable difference in the way the engine runs,most noticeable at idle. Just recieved new cams also,waiting on new chains and tensioners to come in order to do install and then have redynoed for the sert. Cams im installing are woods tw6-6,suppossed to be real good for a heavy bagger. Will report back after install and retuning. Seems wild the response i got from simple plugs/wires,never had a bike respond as this one did.
