High speed stability is often a problem with the setup.
Riding heiht, damping, oil viscosity or spring rates.
On your picture I can see that you have mounted the radator without rubber.
I'm not shure how long the radiator lats till it is vibrated to death.
Only my 2 cents
The show bike is a real eye catcher
Regards Siggi
it was a problem mounting the rad at the yop
this winter will cut the alloy mount and repostion
this will save rubbing the frame
rubber grommet fitted aswell
been a while since I posted.lost my login details.anyways changing the rear end in the bike to a yzrf 125 one.anyone done this before.bought swinger ,wheel etc. all parts came from ebay.de as prices are much cheaper than uk
heres a picture of what ive got
the 125 shock is too small.will try to use a standard 350 one
