front fork bottom out ... springs ?

Have you tried assembling the forks without the spring to see the total travel you get? If it's the full 6.15 inches then clearly it's the springs are wrong and nothing else.

But the standard length damper rods appear to restrict that 6.15 inch fork movement by 1.55 inches, so with the damper rods fitted and the top fork bolts screwed down the maximum fork travel becomes 4.6 inches?

I think a measurement would need to be taken with the springs, damper rods and fork top bolts fitted in place, and then compared with a measurement taken with the damper rods and top bolts fitted but with no springs before saying that the springs were definitely causing the problem?

Personally I think I would want to check the length of the damper tubes to see if shorter (Dominator? Atlas?) tubes had been installed, to identify if the problem is being caused by restricted fork travel or by over-soft springs?

Lab ... I'll do all the normal due diligence over the weekend and take the front end apart , measure all componants and see what the wash up is ...

not knowing the history of the machine could be any of the suugestions mentioned ...

i'll probably come back for some advice after that ...



thanks again

Steve
