| My two-pennorth:
How much increase does a K&N and Dynojet kit give a carbed 600?
Maybe a 620 limited to exhaust changes versus 600 with filter/dynojet/exhaust changes, but no big-bore kits would keep costs down and not handicap the carbed bikes?
Brakes - how about standard (not cast iron or wavy) discs with any master cylinder? To be honest I have ridden a single disc bike and wouldn't fancy doing a race meeting at Oulton/Silverstone/Snetterton on one disc!
Tyres- If you choose (how?) a control tyre, it will always suit some more than others - so leave it free. If people want to spend £200 on a set of wets they will, but at least they won't be the ones to have wasted their bike prep money and entry fees if it pours with rain all meeting........
Cheers,
