xs650 Sumotrack
« on: Feb 19, 2017, 18:10:23 »
Ok, I just picked up a 78 xs650 yesterday for $100.  Plans are to make a street tracker.  It will get an fzr400 3tj swingarm and monoshock as I already have the swingarm.  I actually have 2 of them.  Probably get a set of USD forks, I do want spoked wheels on it. 

Engine will be kick only, at some point I want to rephase for the sound.

1st step is to fix the reason it was parked over 10 years ago.  So rather than fix the stock charging system I am upgrading to a PMA set up.  Parts are coming in so last night at work I went over to the waterjet and made the mount plate to use a banshee stator mount.

Some progress was made today.  First did an actual compression test 110psi on both cylinders.  Carbs are cleaned and installed.  Exhaust was removed, banshee flywheel lightened in my lathe and thats where I stopped.  Ordered a flywheel puller as the right one is cheaper than a 3 jaw locally.  So now to look over the manual that arrived, clean and set the points and get ready to finish the PMA conversion.

Small update, finished the PMA swap, put some fuel in the carbs and it fired on the second kick.

Did some work on the bike when the sun came out the other day.   Complete different look in a couple hours.

New swingarm fits.  It ia from a fzr400rr 3tj.  Aluminum, beefy and lightweight.

Need to get a few pictures, but zx6r forks are on the way, CB550 front hub has started the machine work to be used with the big piston forks.  Intake manifolds for the EFI conversion are started, need to do some layout and get them on a mill. 
 
Finally I decided to call this the Sumotrack.  Reason being is it will have street tracker styling, but it will have fairly modern suspension with 17" wheels.

Thanks, it'll probably take a while since the money for parts comes from overtime.  But having a lathe there are some parts that will be made from material out of the scrap pile, like the intakes.
