Hi,

Thanks for the replies - Ramax... not heard or them, I've heard of a company called Ramair(?) Could that be it? Does anyone know where to get the Ramax filters from for the TA22 TA21 carbs?

The issue for me is that I am building a project bike, and space is critical, so I'm going to the individual filters for space reasons. I'm hoping they will be less restrictive on peak flow, so may give higher top end power, I'm expecting the midrange to get worse, I'm not too bothered as long as it's rideable...

Does anyone have data or experience from riding for how they affect power?

Thanks, Mat
