Post by: jimg1au on October 12, 2008, 07:46:05 pm

hi
last time out i droped an ex/valve in my hagon tt500.it has a big fin sr500 head.i was thinking of replacing all valve gear in and exh.havent pulled apart yet so i dont know if the piston is stuffed.
where is a good place to buy all the parts i need to repair my engine.have emailed a couple of places with no luck or responce.
should i use std yamaha parts or go with after market stuff.
