what is the deal with the large hole on the fmf silencer rear mounting tab? my yz250 came with a fmf pipe/silencer and it has a rubber peg that the large silencer mount hole fits over, however there is no such peg on the blaster. does this mount/hanger usually come with a fmf silencer? on my other blaster i just made it work with a longer bolt and washers. my new blaster has a fmf silencer already on it, but the previous owner was only using the lower mounting tab because the grab bar is in the way. if i were to try to bolt at the top mount the silencer would be pressed against the grab bar and the tab would still be 1/2" from the frame. the grab bar is different on this one, otherwise i would just mount it like i did my other one. it seems like there should be a rubber peg like the one on my yz250, that replaces the grab bar bolt that holds the silencer, however i cant find one for sale anywhere
