Well All and in particular those that provided valuable input such as Ken, Chad, Micah, Frank, Steven and Ian, I think for my purposes I may have finally cracked the CVK Carb Code

I don't know why but I believe I was more on track to get better settings when I first started this thread. The three Amigos above were also backing up my own theory but for some reason I got cold feet and decided to change my settings to one's a tad more tried and tested.

My main reasons for this was, I didn't want any issues on my ride north and whilst my bike ran well, I was disappointed with both the fuel economy and the midrange power to wot.

So Micah's idea of taking my jetting kit up with me was a beauty.

To refresh your memories, I initially was running 42 pilots, Thruxton needles and 145 mains (I pretty sure that was it). I then intended to change the Thruxtons for the less thirsty TBS needles, swap the 42 pilots to 45's and seek advice on what mains to use.

Then even after many of the best replies intimated I should look at richening up the idle and mid circuits and leaning out the mains, I woosed out for some "Nigel Nobody" approach with 45 pilots, shimmed OEM needles and 150 mains.

So today I went back to plan A and this time kept the 45 pilots which are pretty well standard with open pipes and filters, used the TBS needles and as had been suggested, trying a smaller main jet and in my case i decided 140's were in order.

Well the improvement wasn't just noticeable on the butt dyno, it was something else all together. For instance I knew the Thruxtons were good for mid range, but the current combination I have now all seem to mesh in the way we all want ie. pulling reals strong from start to redline and even then wanting to go on with it.

I'm telling you all, Ferdie is now finally playing in a completely new ball game to what he's shown before.

So there ya go. It took a while but fingers crossed the fuel economy picks up now to verify these settings and the spark plugs similarly:
