my friend and i took our wr's in for routine service to our local yamaha dealer (he has a '00 and I have a '98). the '00 still has the throttle stop on it while mine has it completely removed. i questioned our dealer about installing the throttle stop which fits the yz426 (i read in a post that this is the correct length). he said that he removes the throttle stop completely from all the wr's that they sale (even his own).n he also said that it doesn't hurt them with the stop completely out. all i want is the definitive answer. should the throttle stop (assuming it is the yz426 stop) be in or out? if left out, what are the dangers? will appreciate any info.
