JOHN-DYNOSTAR Posted May 5, 2021 Share Posted May 5, 2021 See the holes we did that on Nick browns CBR1000rr H@#%a that did 200 mph at Elvington , it nice to be copied 😀 Quote Link to comment Share on other sites More sharing options...
roddy Posted May 5, 2021 Share Posted May 5, 2021 What's the reason for these holes? Quote Link to comment Share on other sites More sharing options...
JOHN-DYNOSTAR Posted May 6, 2021 Share Posted May 6, 2021 Improves the top end. Too big a hole and you lose the advantage of long stacks. If the hole is too big the stacks basically become short stacks. Dependant on where the hole is drilled. We moved the hole up and down and varied the size to find the best improvement.
