Hello, Wald here, I am new to the forum. Just bought my first VFR (97) after living on inline 4's. I am looking for louvres (or the Ferrari look like cowls) in the fairing for a 97 VFR750. Thank you.

Don't think he is after NACA's...

 

 

But after #25 and #26

Thanks Dutchy, this is correct #25 and #26. I have checked several site in US, not available anymore.  

I found a site in Germany which sells it but this will be the last option.

Thank you,

BTW, how accurate is the Tachometer on the 94-97 VFR? It seems that mine is about 5-8 mph too optimistic (or maybe I am going faster than I think?!)

speedo or tach?

 

U.S. law says speedo can never indicate slower speed than actual. So most manufacturers err on side of caution and have speedo read about 10% too fast. Going 50mph will show 55mph. Displayed 110mph is really 100mph.

Thanks,  I meant speedo. In this case it makes sense. I had it at 110 and it did not feel like it. My hornet has a digital speedo which is only 2-3 mph off.

This site is bit difficult to do quotes, there is a line to click that deletes quote that system carries over  from previous post....

It's the Brits wot done this:

U.S. law specifies a +/- accuracy. UK regulations prohibit a speedometer that under-indicates speed.

Leave them brits alone, they have other problems 😉

 

It is actually United Nations:

“UNIFORM PROVISIONS CONCERNING THE APPROVAL OF VEHICLES WITH REGARD TO THE SPEEDOMETER EQUIPMENT INCLUDING ITS INSTALLATION”

Thanks Magneto. Just browsed through the link you attached, the only involvement missing is the church! Bureaucracy at its best!

Thanks all for Comments.

I have measured the speedometer error to be ~ 8.8% optimistic (higher than actual speeds) on each of my fifth gens.
