My serial number is 225. My stock windscreen measures 3/16"(.187) and the CB windscreen that they sent me several months ago also measures 3/16"(.187)That is true. I looked at the windshield & hardware part numbers for both USA models and the aren't any substitute part numbers. However I haven't checked other (euro) models part numbers.
What I was told was that it would have cost Honda in the $250,000 range to redesign, change a mold, change hole location (and it would be a slight change), hardware change, testing, blah, blah, blah. That is a lot of profit margin on a lot of motorcycles. It is a strange case. The markings on my thick Honda windshield matched the markings on CB thinner windshield. The markings are:
Jupilon
DOT-293 (mitsubishi symbol) M-1040M
AS 6&7
HONDA >PC<
Any one else measure their stock windshield? CB windshield?
That sure sounds reasonable. The thinner shield could be made to install snugly by using either a thin (1/32) flat washer under the mounting screw, or a replacement mounting screw with 1/32 less shoulder. Snug is good when installing at a standstill, but I don't know have it would perform at 100mph. I have no idea what criteria are used to manufacture a stock or replacement shield.H'mm, If CB would stick to a .187 thickness, my guess is that this would work with the thinner shields
That is interesting. Sounds like CB has made thicker shields in the past.My stock windscreen measures 3/16"(.187) and the CB windscreen that they sent me several months ago also measures 3/16"(.187)
Yes, agreed, it almost sounds like ....like...a motorcycle. The acoustic as well as air flow are changing with every change in shield, shield position handlebar height, helmet, head position (varied by your rear end, seat, lean up or left/right).... It can be maddening. I spent ~4 hours yesterday checking my helmet fit in the mirror and riding around covering portions of my helmet to find where the noise is getting in, and then modifying my helmet with some dense black foam to get a more air tight & quieter helmet.The whiny gear noise under deceleration is almost entirely gone. I don't know why unless all that noise is sucked up through the fork well due to low pressure on the back side of a windscreen.
