Well spotted.
It was the first fairing to be designed properly in a wind tunnell ( or so I'm told) and is supposed to be really efficient.

I took a note of the peak RPM at Phillip Island last year and I'm off there next month and I'll do a comparison.

i've also been to the dyno and squeezed a few more horses from it,which means it's not a direct comparison, but hey, if it goes faster I'll be happy.

For the record it pulled 8200rpm with a 2.82 drive box. I reckon I know how fast that is, but I'd be interested to see if others calculate the top speed the same as me.

Hey John - bike looks fantastic!

For the record, what sort of tank is that and where did you get it?

I'm trying to source a good tank design for my R65 build, can't decide!!

It was custom made for me by a guy called John Pearson in England. I gave him the frame with the seat fitted, and he made a tank to fit based on a sketch I did. It was a great job. But it was 15 years ago and he wasn't young then. I'd be surprised if he's still working.

I hope there's not a cause and effect thing going on.
The oil temp got to 114C which should be OK ( Mobil 1 full synthetic).

WOOHOO! See ya at The Island! Looks GOOD.

Why didn't you shorten the lever rather than notch the fairing?

Did you weld titanium to the valve covers or aluminum? I think I'm going to do something like that to rescue the bashed ones I've got.

I come up with 147mph just guessing at your tire circumference. Impressive! Even more impressive than how fast it'll go is that it's stable at that speed.

Where did you find a 31/11 final drive?

I did shorten the lever as much as i could! I saw no alternative to notching the fairing in the end. The lever is only just long enough for me to get four fingers on it.

I welded aluminium to the covers ( well, I got a fella to weld it for me). They brought in a new rule that says " any part of the engine that may hit the ground in a crash must be re-inforced" so I had to weld the ugly plates on the covers.

I borrowed the drive box from a mechanic at the local independent BM workshop. I've been trying to get him to sell it to me for a couple of years.

I reckon the same speed as you. People don't believe me when I tell them that's the top speed, but i think I have worked it out right, and the tacho reads the same as the one on the dyno, so I guess it's about right.

That figure is very similar to the top speeds achieved on the B&S Daytona bikes built by Udo Gietl & Todd Schuster. Quite believable.

When i go to Phillip Island next month, I'll take my new GPS mobile phone with me. You can get it to show max speed.

Now you need to figure out how to transmit your data to all of us out here in ADV land in real time.

Beautiful bike, John!

OT, but since the question of 32/11 drives came up, I noticed yesterday that there was one for sale in the BMW MOA Fleamarket; about 4 pages into the Parts listings. No interest in it mor the seller, but thought I'd pass it on.

32/11 ( 2.91) are uncommon but available. The were used on some R100RS ( and maybe some others)

The one I borrowed and would like to buy is a 31/11 (2.82) They are very rare.

I've never seen a 31/11, but I built a 2.75 rear drive for a guy who was going to Bonneville. The ring and pinion set is still available in Germany. P/N 33121233905.

I believe that is what SAN JOSE BMW is running in that beautifull Bonneville bike that Chris has shown off.
