Hey,

Does anyone out there know exactly what the speed sensor on the R1's reads off of? I believe it reads pulses sent by the sensor as is passes one of the gears in the transmission or something like that, right? Does anyone know for sure? Anyone know exactly which gear it reads off of?
The reason i'm asking is because I want to see if I can emulate this on my '90 FZR400 onto which i'm transplanting an R1 front end(forks, brakes, wheel, etc), R1 bodywork, and a YZF600R motor. I guess you could say i'm building myself my own little R4. I want to also use a '01 R1 speedo/tach since the front end does not have the cable drive for a speedo like the earlier bikes, and am wondering how to go about tackling this project. Anyone have any ideas? Thanks.

Well, the bike isn't done yet...(more)

Well, the bike isn't quite done yet. I'm still trying to amass all of the parts needed. Thanks for the warm welcome by the way. Yeah, i guess you could say I don't like to walk on the same side of the street as most people. Heh.
As for the pictures, I don't have any recent photos but I included some links to some pics of the R1 forks mounted up on my FZR400 frame. There's also some pics on the multitech website of some R1 bodywork mounted up on an FZR400. Let me know what you think. Later.

The spped sensor is on one of the gearbox teeth. It's also where the EXUP signal originates from.

I must say that looks darn good.. I mean, for being "home made"!?..

But I wouldn't enjoy it all that much since it's "only" a 400cc. Err wait you said you'd put a 600cc engine in it. In the current frame?

Are you trying to lower the weight of the bike to something redicolously light? Could work!

A word of advice is that you should get that thing stable on the road. Cuz mixing a lot of body work and engine/parts can seriously change bike's behavior under acceleration/cruising..
Just be careful with it.
