Dan,
Now you've done it! This topic will open up a whole can of worms.
Basically it all depends on how much you want to spend.
I'm building a Cub myself. The previous one I had had std heavy weight cub forks that I reconditioned. Quite frankly they were awful compared to slightly more modern trials bike forks.
This time I tried the following:
1. Bought a cheap pair of Honda CM250 forks from ebay and turned the sliders down so they fit inside the original Cub sliders. This saves making new spindles to mount the front wheel.
2. Bought a gas gas yolk and tapered head bearing assembly that had been modified to fit the cub headstock. This also fitted the Honda stanchions (I made adaptors to go from 32mm to 35mm)
Note: You need access to a good lathe to do the above!
Cost approx £100 and a fair bit of labour to turn the sliders.
I will be putting these bits on ebay at some point as I ended up using the next option for my build:
3. Purchased a set of early Montesa forks and yolks (I actually ended up with 2 sets!) and modified the billet Montesa yolk assembly to fit tapered bearings (not really necessary but nice to have). I ground the outside of the bearings to fit my Cub Headstock.
Note: You will proably have to make a new front wheel spindle and brake arm assembly.
Cost approx £200 including reconditioning Montesa forks (most forks this old are knackered)
The bike may not be eligable for some pre 65 events. As I intend to use mine for local club trials I'd rather have front suspension I trust.
You can always try to refurbish the forks you have but from my experience I wouldn't waste the money. The other option is to keep an eye on ebay as modified forks often appear but good ones go from £150 to £200+
If you want any photo's of what I have done send me an e mail. There is an early photo of my cub attached to my thread 'modified cub swing arm'
Hope this helps.
Bruce.
