[QUOTE="westgl, post: 100736, member: 2025"] Joe hooch is a different animal all together. I was just thinking out loud, between all stock engines and some comparisons. I was looking at the direction that Honda went. They must have thought the longer runners, smaller head intake ports, & less carbs was better too. The GL1500 & GL1800 FI were the direction honda went to, be it for economy, smog. Funny that the GL1800 head port size is 1.100" ID with 300cc per cylinder same as GL1200 That 1.100" ID is close to Rev.1 tube ID, Rev.1 did not have any chokes in the VW plenum Outlet. [/QUOTE]
