jason, the productions class has been exstreamly fun and rewarding, and if you already own the bike most economical.
i took my sons 2002 Buell X1 white lightning and set, broke, and bumped records in multible classes. i did all the work needed for it to pass tech in house myself, also took the wealth of knowledge found here on the site and continued to go faster, faster and faster.
i plan on trying to get 160mph out of it in its oem configuration while keeping it street legal. [while i build bike no 2 for the goal of 200mph]
a rule book is the key, that way any questions you have can be refered to in the text of the actual rules.
by all means make it a family quest, my wife is my crew chief, my brother is my crew, my son is the bike owner. and yes driver changes are allowed.
as far as the ECTA, they truly are the best group of people i have met in the motorsports comunity.
see you in april
any questions just ask
