It's a 1984 TY 250 mono. It's got the shock with the remote reservoir.

I've taken the preload to the max and wound the spring to it's tightest setting with the two locking rings.

The back end bottoms out far too easily - I'm about 100kg with all my gear on. 

 

Is there anything else I can do?

Does anyone do a heavy duty spring?

Should I put a packer  in front of the lock rings so they compress existing spring more? My guess is I'll lose some travel but it might be worth it?

 

Should I lay off the beer and pies to lose a few kg's (I think this has to be a very last resort)?

 

Any advice greatly appreciated.

 

 

 Are you riding trails or trials? Most trials bikes can be bottomed out easily, but an `84 is pretty old and though that is not the original shock.

Before giving up beer or pies, I'd recommend working on making sure you flex those legs of yours until your butt hits the mud guard. We have the best shocks ever made connected to our feet!

I am riding trials and I do flex my legs.
