ok guys thanks for replys
as i said probably not the best looked after so in the middle of doing a few bits
sprocket bearing ,crush rubbers, bell crank bearings and swing arm bearing with the bolt sized in it
also every bolt on the bike seem loose including engine bolts and sprocket bearing was nearly seized which would help with the vibes
so everything order and on the way and i ll see what its like when back together and get back to you
any tips for getting swing arm pivot bolt out its badly sized, hammer is not the answer bolt just swelling
thanks again
