Before you read on, this isn't one of those threads where you will marvel at any craftsmanship, just an opportunity for me to tell the story of my XS over the last six months. Iâ€™m posting this thread retrospectively for anyone who might like a read. I picked up this â€™73 about six months ago, I paid $4000 AUD ($3100 USD), it had no registration (title) and wasnâ€™t running properly. It would idle fine, but no good under load. I took the risk and bought it as it had good enough compression (135 PSI when tested wet), decent spark and matching frame and engine numbers verifying it as a 73 TX650. The bike was set up as a lazy cafÃ© racer; I donâ€™t like that look one bit, and planned to try restore it back to its 1970â€™s roots. I got it home and realised it had no air filters, so that was the first purchase. I then realised both the factory vacuum petcocks were completely useless, so ordered two new non-vacuum petcocks also. I then replaced the stock taillight with a Lucas replica taillight as I liked the style. The bikes lead acid battery was testing poorly so I replaced it with a Motobatt. I also replaced the OEM plug leads and caps as well. I thought about replacing the coils, but they tested well and are throwing a decent spark for now, and I had more pressing issues that you will see in a second. Next up was bars and grips. I got some cheap pull-back style bars from japwebike with white grips just cause I liked them. Iâ€™d already spent enough money in two or so weeks to this point so admittedly I cheaped out big-time here. Then I replaced the throttle cables with OEM parts and the clutch cable too after it snapped in my driveway. The next to go was the ignition barrel, as it was bored out and the key would barely fit. I just removed it and replaced it with a simple 3 way switch drilled straight into the top of the headlight, I sealed the hole up with some silicone so it was water-tight if I am ever riding in the rain. So, then, after approximately two weeks of wrenching I was ready to start riding with some regularity, most afternoons after work. I registered the bike as a 1973 TX650 which was an experience in itself. It had no compliance plate and they had no information on file for that bike. I was basically at the front counter of the RMS (DMV) telling them what to register it as. I was on my iphone googling the bikes weight, capacity, year of manufacture etc while telling them what to type in. Pretty quick I realised things werenâ€™t too great. It took me about a week and two breakdowns to realise the charging system wasnâ€™t working, at all. So, four pages of posting in the charging system guide thread and plenty of help from 5twins, 2M, Gary, Retired Gentlemen and Brassneck later, I diagnosed the problem to be a faulty factory rectifier. I then replace the rectifier and regulator with an eBay three-wave rectifier for 5 bucks and a VR115 Jeep rectifier for 25 bucks. These items were bought from overseas, so took approximately a decade to arrive. No riding for a while. While i was cleaning the grounds as per the charging system guide, I broke my starter solenoid (be careful for anyone reading, the plastic casing is easy to break), so I ordered one of them locally and wired it in a few days later. Took this opportunity to have a look at the running condition. The bike was blowing cold air out of the RH exhaust and fouling the RH plug instantly. Running on one cylinder. Had plenty of spark and was getting fuel, so assumed it was the carb. So, time to read the Carb Guide 2500 times and have a crack at finding the problem. I had a suspicion it was flooding as there were times when it would run one two cylinders for about 5 seconds on start-up before dying. So I take the carb off and what do you know. The post that holds the brass float has been snapped off by the PO and he has tried to fix it with wire, poorly. The float is not working, I double-checked this using the clear-tube method. (photo stolen from google) I spent about a week trying to work with the broken carb that I had before I got very frustrated and called the local XS650 wizard and asked if he had a spare RH early BS38. He sends me one for 100 bucks. Not bad. It arrives and itâ€™s an XS1 Carb, slightly different to my 73 carb, particularly the choke mechanism. So I ask the forum, and they say donâ€™t mix them, bad idea, etc. I figure, why not give it a go. So I used some vice grips to pull out the feeder tube from my old carb and attach it to the XS1 carb I bought. Everything lined up perfectly except of course for the choke feeder tube, so I resign to the fact I no longer have a choke. Jetting for these two carbs is â€œalmostâ€ identical. I then synced the carbs using the dead cylinder method and put 100 or so highway kâ€™s on it. What do you know? Both plugs were nice and tanned. Seems to work. I bought a stepped KQ seat from a 74-78 but it never fitted quite right (at all) and I ended up attaching it with cable ties and using it anyway for the better part of 3 months. Sometimes on acceleration the cables ties would snap and the seat would move considerably in the pan, pretty scary. I then replaced the standard tubes with 6-overs that a friend had from an old XS chopper he had turned into a cafÃ© racer (why). The seals and springs were all reusable, nothing seemed to leak. But due to the extra length in the front end, I needed to get a new front brake hose. I got ride of that weird metal manifold and just routed a cable straight from the bars into the caliper using a 10mm male seated connector. That manifold is ugly, and very easy to snap. Finally, I sourced a HBKQ and sissy bar from a fellow in Wisconsin, and it was in the mail. Well, it arrived this morning and now Iâ€™m pretty sure my restoration is complete. I removed the indicators, front and rear, as they arenâ€™t legally required on pre-1976 bikes in my state (New South Wales). I removed the front fender too, Iâ€™m thinking of putting it back on. Hope you enjoyed.
