I was thinking that well I have got my TLR forks apart I might as well try to improve them ,is there anything I can do though? I'm a big lad which doesn't help.

Would fork springs out of any other bikes help ? (stiffer springs?) (the forks are too soft).

Hardly any oil came out, is this normal ? And there was certainly no air in them.

Would a higher weight oil make them any better ?

They aren't what you'd call the best operating forks around, both damping and springing too soft which becomes more apparent the heavier you are. Bit like the TY250 Yam.

Try 15 - 20 weight oil, not much point in exceeding the recommended oil level by more than, say, 10 - 20cc or you will just get hydraulic lock.

Packing the springs with additional spacers will only result in the spring becoming too compressed before you have even started to depress the forks. New springs are probably still available from Honda as yours may be well used by now in a 20+ year old bike but even new they will still be too soft. Maybe WES do replacements for the Hondas?

Or chuck them away and fit a pair of Marzocchis like those fitted to Fantic/Beta/Armstrong etc. Much better and they are the same diameter as the Honda legs. They come up on ebay from time to time.
