Hi, glad to have found this site. My ´87 had a full yoshi pipe works great but is flattend on the bottom and has too much rust to ignore. I like some ideas to round out the header pipe or fit another. I saw an ONTARIO header for sale ong ebay that was for an ´89-´90. Nice piece ... brand new w/cermic coating. Does anybody know if it will fit. The auction is probably closed by now but I think the seller had more than one and I´ll find it again. I´t a great bike and I´ve done quite a bit to it and know it´s time to make it look good ... not too good. Don´t want anybody to steal it. I like that I don´t worry about that too much.
