I had almost 2 seasons of this, and it turned out to be the front end of my JKH/Intrepid just needed to be lots stiffer. Even in Clubman you're stuck with the new slicks. Things that helped:
Get the seat as far back as possible. Fit a 3 mm floor and bolt it up really tight. Run tyre pressures as low as you dare (8 psi for me on a hot day). Narrower front rims (I use 120). Low front ride height. Seat stays.
Things that didn't help:
Expecting to be quick without testing. Some of the advice I got (so take mine with a pinch of salt, worked for me, but you need to try it for yourself).
Don't shell out for new kit or return the tyres, they can be made to work pretty well, but within the realms of making an old chassis work with tyres that it wasn't designed for. It took me lots of rib damage, trips to the osteopath and physio before I figured out that a 2005 kart [B]could[/B] be made to work with the new tyres - and once you've got them working it's just like TKM of old, but you're going a fair bit faster.
I've built 2 of my own chassis now, very much based on the 2008 JKH design, and I'm starting to get some half-decent times without the kart ripping my shoulders out, bucking or trying to take-off. The one thing I haven't done is splash out on a recent Tony, as I know this can be done within old fashioned TKM budgets...
