Hey all, while I have put the 03' cam mod for my wr426 on hold for now (money issues), i want to change my timing. While I was checking the valve clearances yesterday, i noticed the bike was yz time (12 pins I think). Since I bought the bike used, this is new to me... Anyways, i rarely find myself in the upper rpm range, so its pretty useless to have it yz timed. I ride ALOT of relly tight technical stuff and i feel the stock timing would work for me better.... My question is, will i lose performance, or will the powerband just be moved down? Also, if i change back to wr time will I have to reshim? My valves are in spec as we speak, so can I just change the timing and go? Thanks guys!!!!
