Any love for the TX750 step child?

The roll-out of the TX750 did not go so well, but they are really nice bikes to ride. I found one in a junk yard back in 2011. I had no idea what it was, but I loved the look of the motor and tank. The one I saw was bobbed out, in primer and had been outside for many years.

I got it running back then and rode it for a few years. Always smoked and I had a hard time getting the voltage regulator set to cooperate with the small Li Ion battery I had it it at the time, but the motor was great to ride. Very torquey and smooth.

I ended up selling it to my buddy and he rode it awhile until it spun a rod bearing. It sat in his shop for years until I bought it back from him last winter.

I was planning on doing a road race replica. It is a 1973 and if you’ve heard about those they a very prone to frothing the engine oil and stretching the balance shaft chain throwing the 2 balance shafts out of phase. This bike had the dealer mods to remedy those faults. It has the extended oil sump and the adjustable balance shaft chain.

One thing it did not have was the forks with the option of putting on a second caliper like the European models had. I know there was another TX750 in that same junkyard. It was laying on its side back in 2011 and I went out to see if it had the left fork lower that I could use to mount dual calipers with.

It did and for $100 he loaded it in the back of my pickup with a front end loader.

I found the gas tank laying 20 feet away and headed back to the shop.

I thought I might be able to use the crank since the other bike spun a bearing. When I pulled the motor and opened it up we found why it had found its way to the junkyard. One of the exhaust valves broke and bounced of the piston. But surprisingly the motor from the cylinders down was in excellent shape.

Fast forward to now I got a title for it, the motor has been rebuilt with the adjustable balance shaft and extended oil sump from the original bike, I built a new wiring harness for it eliminating the reserve lighting mess and it runs.

I’ve set it aside for most of the summer because other projects came up.

I picked this up in the spring. It hadn’t run in years, so that took some time to get it on the road. Great bike though, definitely one of my favorites. And then most recently I’ve been finishing off my XS650 dual sport project.

I’m also wrapping up a 1986 VFR700F Interceptor that I picked up this year. That should be ready for paint in the next couple weeks.

Then it’s back to the TX750. Now that I know it runs with the rebuilt motor it’s time to strip it down to the frame and start the refinishing process.
 
A nice little stable you've got there. How bout that BSA.
It’s a 1971 Lightning that I got when a friend of mine passed away and I bought it from his daughter. Same story as all the rest. It hadn’t run in 20 years or so.

It is a very nice bike. I did all the standard upgrades and it rode very well.

I rode it a couple years and then traded it to another buddy for a 1997 Buell S3 that it a bit more fun to ride.
 
You do have your work cut out for you on the TX750. I rode one back in 73 when I had my TX650 and I thought it was a pretty nice bike but then the problems. Gotta give you credit for diving in and getting it back on the road. There have been a few bikes I have done that were questionable projects but the TX750 takes the cake.

With the TX750 rebuilt the rest of the bike is like any other. I don’t have any experience doing body work and real paint. Fortunately the guy whose shop it is does. He’s helping me with the VFR700 now and will be helping with the TX later this winter.

I also have another diner bike that another buddy (guy who just donated the XS1 motor) gave me with some good parts.

That’s where the gauges and exhaust came from.

..... and they swap right onto the 650. The benefit, besides the nice D.I.D. rims, is a larger rear brake .....

The front wheel should also have that nice alloy left disc mount cover .....

The swingarm is pretty much an exact copy but with one important difference - the tubes are about 1/4" bigger in diameter, and that makes it much stiffer .....

I got the VFR700F Interceptor body work to the point where it’s ready for the first coat of primer yesterday. He’ll be leaving for a trip so we won’t do any painting until after the new year.

That gives me a chance to get back to the TX750 project and get the shop cleared out of the extra parts I won’t be using for this project.

I’m going to concentrate on the stock (ish) TX750 for now, so I need to do some parts swapping before I take the other one home and get rid of the third frame.

I need to swap the fork lowers and pull the rotor from one of the wheels to allow for a dual disc setup. The fork tubes from the stock bike are shot so I’ll need to swap them over.

I’m also stealing the front brakes for now.
