i need some advice or opinions please my front forks seem very hard over bumps especialy at high speed, ive tried different springs and oil weights and oil levels, theres been a slight change but no matter what ive tried the front forks just dont seem to be absorbing the road like they should, any bump is just comming back to the bars feels like i have 50 pound of pressure in me front tyre. ive reduced the tyre pressure to 25 pound and theres a slight change but it still feels hard over bumps.
so i am stuck its either the tyre avon roadrider maybe the rubbers made from bouncy ball rubber

cheers ...................
