If only were more forthcoming. Scooterotica forum was founded off the back off Sean and I sharing port maps, porting specs, and general garage shenanigans. Once the dyno took off we were able to also share definitive figures for work done and results achieved, plus how different kits/pipes performed out of the box, etc.
We enjoyed that, but Darrell's work is extraordinary in my opinion. He is relentless in his focussed pursuit of development, and although he does keep a few cheeky secrets for himself, his affinity for sharing large portions of his research and knowledge is amazing. He is not a natural when it comes to writing, so it takes a large effort on his behalf to collate all the results, attach accompanying pictures, and write up in a methodical manner. So it's not just the work he does first to get all these results, it's also the associated work afterward to put all information together.
