XS650 Road Race Restoration

[Lost On Row 1]

I think rubber mounting is the way to go. Thanks for all the efforts and suggestions so far. Just to remind everyone, it is Bill Brown of Historic Moto Gran Prix who owns the bike. When I got it there was a powder coated frame, with the suspension and wheels bolted on. (sorta) There were several boxes with motors. I used the best of what I had, or new if needed, to build a engine. The cylinders were bored and plated for 750 pistons.
So I am just the assembly Guy. The bike is cool and a piece of history to folks like myself. For me it has been a great opportunity to help restore a one off bike. Not to mention, I will be one of the few riders to ever get to go around a track on it.
Not only did I figure you all would dig this thing, I really wanted to open it up so I could pull from your experience and abilities. I can make stuff work the way I know how, but that's it. I don't know, what I don't know. But I do know, I don't know it all. Please shoot ideas on the bike anytime for me. I appreciate the great reception and interest.
It will be quiet here for a few days. I am headed to a 2 day track day at Roebling Road near Savannah, Ga. Sadly the DG won't be ready for this one. I will have the opportunity to ride a couple of old Factory Yamaha's.
Not bragging...just pumped!

The 4 bike is a complete replica of Eddie Lawson's. Yamaha factory parts throughout. Same wheels and all.

A bike that Jimmy Felice and Rich Arnez rode in the 1987(?) season. This is going to be tough, Felice is short, the pegs are way high. I will struggle through for humanity though.

Way to take one for the team! (drooling with envy here....)

Haha! Hey if I don't ride like a total dork I may get to try out some other stuff.

Just heard from Pamco Pete and our ignition is on the way. He has been very helpful, look forward to getting it installed and hearing this bike run.

Here is a link to the track google map. The straight is huge.

The exhaust on this bike is definitely unique. I have been told that the pipe comes from Dan Gurney's F1 race cars. It sure looks the part. I haven't been able to find a match on any of His car pics as of yet.

Very cool bike and opportunity will be watching for sure even more since your a dirt tracker!

 

[Lost On Row 1]

Cut me and I bleed.....Blendzall or Castrol R40 . So in other words, I am a old dirt tracker. I have been fortunate to have tried different types of riding and racing, my favorite still is dirt tracking.

Nothing like it....

Anybody got a smoke?

Back to the shop in one piece. Thank you to Pamco Pete for getting our ignition out to us. Looking forward to making some progress this week.


The older bike did not run right, so I had to ride the R1. The things I do for people.

Last non-XS picture, hope no one is put off.

This thread is too good to get lost. Bump to the top.

 

[Lost On Row 1]

I apologize for the lack of progress. If the shop gets slow all I have to do is push the Gurney bike on the lift. I will get an update and pics up very soon. I have let humanity down.
But hey, here is a pic. Any guess who is who?

I have a request for suggestions and pictures.

I have a couple mounting challenges. I am open to thoughts or ideas. I know this thing will have some vibration. I have been given a Lockhart oil cooler and think it might work out best in the position of the original (huge) cooler.
Anyone have experience using this type of cooler mounted this low?
The right side cover is where both lines attach.
How about any suggestions for making the existing mounts work.
I don't want to modify the frame at all.

Here is a pic of what i have done to mount the same cooler. Angle brackets off the front mounts. Cool looking bike.

Feel like I am on the home stretch on this bike. The longest home stretch there ever was.

Definitely getting close. This is what I am doing with the coil and the e-advancer from Pamco.

I need some help, if possible.

I have a Pamco Ignition with the e advancer. We are running a total loss system so wiring is fairly straight forward.

Sensor to advancer: match up the colors.

Advancer to coil; Red to the coil wire that also has battery voltage, green to the other coil wire. Black to ground.

The coil is rubber mounted but has a wire as a ground from mounting post to engine case. The battery ground goes from batt to same engine case bolt.

We have no switch or kill button. (yet)

I had everything hooked up except the wire to the positive battery terminal. I checked my ground on the coil to batt and coil (coil mounting post)to ground.
As soon as I touched positive to battery the small ground wire on the coil (pic) smoked in half. It appears to be a non insulated wire from the coil to the mounting post.

What did I do wrong here Guys? Is the coil faulty? I even need help coming up with questions to get help.

Thanks in advance. (no pun intended)

Haha, yeah, I had the same rude awakening. Don't ground the coil. Follow RetiredGentleman's posts in this thread:

So remove the coil to ground wire. Did I ruin this coil? Should I repair the ground wire on the coil that fried? Most important, did I hurt any Pamco components?

 

[Lost On Row 1]

It is 11 oclock, I am still in the shop....I appreciate your response TwoMany. It gives me hope.

I am getting "that look" from the help.

[TwoManyXS1Bs]

Yeah, I've seen 'that look' before.
G'night...

 

[Lost On Row 1]

I removed the ground from the coil. The burnt wire has 12 volts on it. That doesn't seem right. The bike sparked just a time or two and then nothing.

It Sparked! Glad for that.

Any thoughts on how to get my spark back?

 

[scabber]

The 12 volts on the burnt wire is why it is burnt. Remove and toss. 12 volts to coil terminal and wire advancer and pamco from there. The advancer and pickup are powered from the coil. The black wire from pamco should ground to motor and not connected to coil.

 

[scabber]

Red green to coil black to frame ground.

Red green to coil black to frame ground.

Yes it is.
