Question.

Do I get someone like Maxton to rework my existing standard forks or am I going to get better performance from an alternative set eg YZF750 front end ??

The cheapest and GOOD option is to buy the correct rate fork springs to suit your weight, some valves / emulators to increase the damping efficiencies and a rebuild with new and likely heavier weight oil.
Try contacting KTech for advice and the costs involved in supplying the parts you need, many members have gone down this route :

I`ve decided I want the bling of an USD set-up so am using a set of R1 forks rebuilt to suit my needs.

Thanks, like you I'd like to see an improvement in the performance with some bling too, surely the R1 forks are going to out perform anything I could do with the std forks ?

Not necessarily, reworked stock forks will perform just as good but without the bling obviously. You pay your money you make your choices.
My forks owe me a fair few bob, but they are sexy, even got titanium nitrided sliders.

USD forks are invariably stiffer but I very much doubt any mortal would notice the difference on the road. They also offer benefits in unsprung weight - again refer to my previous comment.

I have had standard forks - and they were OK

New fork oil and springs - even better

Standard forks rebuilt by maxton - even better

Replaced with YZF forks - about the same, maybe worse

Rebuilt YZF forks - better than rebuilt standard

Don't overlook Thunderace (48mm) forks. They're rwu so aren't as 'desireable' as usd forks (so are cheaper to buy!), but they work really well
