I can't say I've ever seen a race and performance section since I've been a member on here.
If you go to the 400/4 section though you'll see a lot of discussion about the amazing performance of Parakeet Yellow 400/4’s 😁.
There's also quite a bit in the 750 section about the CR750 and even a thread by a member CR21 about his absolutely amazing build of a CR750 replica, well worth a read, look it up using the search bar 👍
