New to forum, need advice
Posted November 17, 2006 - 12:01 PM
I have a Cycle Factory flat track frame with Kosman wheels, Ceriani road race forks, Champion Glass, that I want to make into a street bike and maintain the classic flat tracker look. I am and was a Kenny Roberts fan. So I was thinking to put a Yamaha motor into that frame and the perfect motor would be the 450wr. Electric start, wide ratio gearbox, something to loft wheelies at the flick of the wrist and paint in the traditional Yamaha yellow and black.
So here is the question, can I get a 450wr motor anywhere, preferably used up and needs rebuilding or am I going to have to get a crate motor? And does anyone know of any sources of motors aside from going to a Yamaha shop and getting hosed down?
Thank in advance,

I was wondering if there is a grey wire mod for the 07. There seem to be conflicting views on if there is. Does anyone know for sure if there is a timing advance mod?

There is also a air box snorkel to yank out, along with air box cut outs. Make SURE the PO did the throttle stop. You will need to re jet as well.
If you really want it to scream, get a good pipe, and cams, either YZ exhust, or Hot Cams, but if you go the YZ cam route, you may have e-start issues.
You can find endless threads on here to wake the motor up to what it should be.
Oh, did you yank the AIS yet? Of course if you have this on the street, a lot will depend on your local law for the pipe selection, AIS, etc.

I found several threads on how to wake the thing up but the grey wire on an 07 was still up in the air. I want to keep it quiet as possible but a good pipe may be in order.
I had heard that on the 426WRs one could advance the intake cam one tooth and it would be like a YZ. Nothing like that on this?

The Hot Cam's however, will not give you E-Start issues, as they have the correct decomp pin. I have Hot Cam's in my 04 and e-start work's great.
I have NEVER heard of a 07 WR in the US NOT having a Grey Wire
