Was reading the Superhawk forum about setting up carbs using the link Wicky posted in another thread http://www.superhawkforum.com/forums/te ... -up-24769/
Now they go into great depth about setting up the carbs etc.
There are some on there that say it is not possible to set them up properly using K&N filters and they recommend keeping the stock air filter.
Anybody got any thoughts either way?

Re: K&N vs Stock filter
I run a K+N and mine fuels beautifully.
If your tech finds it difficult, go to a better and more experienced dyno operator.
Before booking a dyno, I'd suggest that you ask them to show you printouts from VTR's they have done before..... if they can't, they haven't experience with these bikes.
The size of the carbs means that they aren't as straightforward as other bikes.

It's not falling off, it's an upgrade opportunity.
Re: K&N vs Stock filter
I never got mine quite the way I wanted it with the k&n, there was a bit of a torque dip at 5000revs..but I didn't have a dyno run, just tried to jet it my self.
I read all the stuff on the Superhawk forum, and did what they suggested and tried to go back to stock, and although the dip disappeared, so did the top end pull. So I went for a 3rd suggestion from the same thread which was to try the BMC filter ( the road one not the race one) as that is half way between stock and K&N flow. That one now has the linear torque curve with no dips and the top end, so I am happy
I have race cans and a DJ kit fitted, and when I put the standard filter in the tank range dropped from 100+ miles to the red light down to 85 miles, so that shows the impact it was having on airflow and fuelling! With the BMC I am back up to 100+ miles till the red light.
