With homemade taller gearing it has run over 300kph, long time ago. Stock gearing did 235 kph. Now I guess with the FJR parts it will do 265 kph.

Thanks! tire is absolutely straight behind the front wheel (and no, the front wheel is not offset).
Here a pic of the start of the project. Notice the distance between U-joint and shaft in swingarm..



Because of the different swingarm construction the left frame pivot point has been deleted as such and the frame has been modified to accept the new axle pivot point. A 3cm wide spacer was needed to get the middle drive gear inline with the shaft.



Deleted stock swingarm pivot point ... now houses the speedo drive sensor..



Two longer middle drive gear shafts... one lengthened by welding, one completely new one-off. Both 3cm longer than stock.

Aaaa.... uummmm... yep 300 kph on an XS11 might just about be fast enough Hells teeth, you'd need to be tucked in low, 300kph on a naked bike, you wouldn't want to have long legs and arms...

HOLY %&$#@!!! Awesome!!! Math, you are a Master!!! Simply having come up with the concept, let alone to realize it makes you somone special in our ranks. Can we automatically elevate Math to Guru status?

[Mathh]

Thanks a lot for the compliments. I'll post a couple of detailed pics for the real lovers.

New lenghtened middle drive shaft (the one on the left)



Hydraulic clutch engagement. Just made a small adjustable adapter between the cylinder and clutch actuator to fill up the gap.



Oil filter adapter plate with thermostat and cooler connections:

Kawasaki DFI set up slaughtered und put together again in the correct intake width:



Computer Electromotiv:



upper cable is for EFI Injection, lower for tacho drive



Coils from Electromotiv:



Lambda probe welded into the interlink pipe between turbo and muffler

[Mathh]

Honda SP-1 cockpit and RSR air/fuel gauge:



speedo drive by NPN-sensor (in the abandoned swingarm pivot housing) reading the number of teeth passing from the modified transmission gear pressed onto the U-joint..



fuel pump and filter:

One word: WOW How long did it take you to get/make all of those parts?

Well...........since 1982. Then I bought it new and after 1500 km of running in I bolted on the kit from American Turbo Pak. The bike has been altered a number of times since. You can see its history at
www.xs1100.com under "projecten"

In total it has seen approx. 200.000 km now and a new change is on its way as I think the alternator and seat are too big and the Electromotive is good but as you call it: a dinosaur.

i went thru your website a little, and in 92 you enlarged your gas tank, awesome!
i like the obessesion you'ver had since day one, definately a first rate engineer and designer!

gotta ask

do you know what the final drive ratio is?

mmmmm, this is what I could find about the FJR1300 (5JW1-AG1):

"Primärübersetzung: 74/48 (1.563)
Sekundärübersetzung: 35/36 x 21/27 x 33/9 (2,773)
Getriebe abstufung:
1. Gang 43/17 (2,529)
2. Gang 39/22 (1,773)
3. Gang 31/23 (1,348)
4. Gang 28/26 (1,077)
5. Gang 26/28 (0,929)"

Now let me know what you are going to calculate?

Welcome fellow new member. This is surely a very cool bike. But when the only stock item is the motor, at what point is it no longer an XS1100?
