It appears you like golden showers, then...

Yes, and  better too 'cos they'll have the preload adjusters the 98/99 bikes lacked

This what you're looking for? looks like cables on it too, tho not sure what condition they're in....

Fiddled with the TPS but still couldn't get an acceptable setup, so I've put my Advancer back to the standard position and she's much smoother again above 4000rpm.
I know a few of our U.S. cousins had problems with the Advancer fitted in conjunction with Ivans, and the great man himself thinks its not the best setup for our bikes.

A pity as I can see plenty of others not affected by this mod

Huge amount of discussion on this topic: agreed consensus appears to be that there is no general consensus.

It depends on your height, your helmet, riding speeds, whether you have higher / lower aftermarket handlebars, higher / lower aftermarket bar risers, the standard mirrors and how far in front the fairing sits. 

I have an MRA Vario which is the same size as the standard screen but has an adjustable vane, and a Givi D129 which is about 4 inches taller & 1 inch wider. To me, both are better than standard, but neither is good enough. The Givi transmits a *lot* of extra noise & along the top it 'vibrates' above 60mph. The Vario is quieter but seems ineffective in all but the highest vane setting, whereupon it deflects all flies straight onto to my visor.

Remove your mirrors, go for a ride & see if that makes a difference.... or alternatively keep them on & remove the screen to see what extra turbulence factors are at work...   

Not many tuned examples about with engine work.

You could probably get high comp pistons or go nitrous but don't think the clutch will take more than 150hp without expiring.

Ivan's jetkit with a full Akra or Muzzy header system seems to be the limit for road use - about 140hp.

Probably doesn't help to have the bike lumped in as a derivative of the Thundercat as per the Haynes manual?
