Thanks for the compliments. I probably can't help you with the Jenvey stuff as I suspect the angle and overall length of the Jenvey manifold, throttle bodies and air horns will be different than what I've got. I'm running the JC50/75 and it's a tight fit. I believe Quinn is running the JC50/100 on his NB with the TWM standard 35mm length air horns. Wildo is running a massive JC50/150 on his NA with 100mm long air horns.
