Deez, forks are soft! Try adding a 1/2 inch spacer under spring, and 15w oil. This will stiffen forks, and slow down rebound so they won't pogo. If you just go with heavier oil, the forks tend to pack up, they can't rebound fully before hitting the next bump, and make for a really harsh ride.

Deez, yes they do bottom out! Try using an aluminum spacer that fits in tubes. I think progressive used to make them back in the day, but you'd be hard pressed to find them now.

Yes,

I'm busy with this, but it will take time to sort out.
see the link superhawk meets triton

as said, I changed the suspension of my Honda CB400F with very good results,
The person who has to make these springs is working as a technician in this area.

He will do this in his spare time, so I have to be patience.
If you like, I will keep you informed,
