Ok so I've got piddly little cx500 forks on my trike. When I go round corners I think they are twisting a bit. So I thought I'd Change them to something bigger and beefier. The thing is I've been told I will need to cut the headstock off a weld a new one on. Is this right?

Not necessarily. It's a matter of finding the right bearing setup to suit the headstock and the trees. Try this http://www.scribd.com/doc/3565510/motorcycle-steering-stem-bearing-sizes |

Getting older but no wiser! Just using bigger hammers.
The answer to most problems, fire and lots of it.

Or press your stem out and get the new yokes machined up to fit

No dramatic mods are required, as I have had similar probs. in the past with the GL/CX fork set up, so I swap them for Honda F1 750cc "4" forks. All that's required is a bottom taper roller change, see the attached pics. to illustrate, ...Morrag

No, not really, and for the MOT I would fit a new guard of flatter section, made from a section of discarded rear trailer mudguard, and that satisfied the MOT tester, ok....  Morrag |

I would rather fit a brace but as I have a 19 inch front wheel I may have to lose the mudguard

There used to be a company called Telefix that sold fork braces for all makes of bike. They were in several parts, a pair of 2 piece clamps that fitted around the top of the fork bottom, & 2 straight sections that bolted between them with a little adjustment in the mounting holes for a good fit. They still come up at autojumbles.
I made my own for my last Reliant trike. Had a local engineer bore fork sized holes in 2 chunks of aluminium, with clamping bolt holes, cut them in half to form 2 piece clamps, then had another mate weld a flat bridge between them. Then spent weeks filing the ali to shape. Looks good though.
Here's a "Screamin' Eagle" Harley one on American Ebay for $25.

Or you could make a hooped one, like the one on my XS650. 2 flat plates bolted to the mudguard mounts on the inside of the fork legs, with 2 hoops welded to them, over the top of the tyre. Just about visible here. This one's just for show really & gives me somewhere to fix the guard to, but you could make it much beefier if necessary. Used a lot on American flat trackers.

Found a firm that does braces but they have 4 different one for the cx500. How do I find out what forks I have?
