My 500 YZR screamer project
Hello, I know there are no pictures of the progres of my bike, but I am very pleased to show you the result before painting.
This bike was built between several projects. It took 10 years but what a joy to have finally running.
His first trip was made on the circuit of Nevers Magny Cours during the meeting organized by the French 500 rdlc club.
I hope that you will appreciate and with time (lot of), I will place some additional photos. After the first main jet change

Re: My 500 YZR screamer project
I still running slowly the engine so I can't give you all the informations. But Thanks for your wow.
For the vibrations, as I kept away the balacer shaft, there are some vibrations. I don't know why but only during the deceleration (aroud 7 000 rpm).
I'll give you more information after the next setting ( main jet, curve ignition setting, air boxes, ... ) because I still have a lot of details to finish the project.

For now I run with cdi units from 250 tz 4 DP40. Next week, I'll get two fully programmable units form DEVMOTO.

Re: My 500 YZR screamer project
Very nice work! Does the taper on the standard rd500 lower crankshaft fit the taper on the tz4dp flywheel?

Re: My 500 YZR screamer project
For thé cracks, I have uses 2 front one but unfortunatly you have to machined it to fit thé TZ flywheel.
Re: My 500 YZR screamer project
In wich way have you changed phases between the two crancks ?
you can not obtain a 90° rotation with a 31 tooth gear.....did you build a new gears ?
