1974 XS/TX650 rebuild

[th62]

I picked up the seat today, looks alright. I'll be attaching a polished aluminium ring around the cowl, as pictured, to stop the seat cover from peeling off the cowl. Can't decide on whether to use the ally strip as is or extend it to the base???

Couple of pics of the finished bike, plus a quick video fly around. Lots and lots of mods on this one, not a great deal of Yamaha left.

Most excellent job. The only thing I see that might warrant some attention is a oil filter gard.

So the big question is, What's your next project?

Well done, so what's next ? :-)

Test ride.
I can’t ride anymore, buggered hips, fused fingers, buggered toes and no elbow joints left make it impossible. But the time had come for the bike’s first test ride, so, I started the bike and rode it gingerly out of the workshop and up to the garage, legs stepping as I went, and there I stopped. I was going to give it a shot and ride it up the street for a test ride, by the time I got to the garage I just didn’t have the confidence I could hold the thing up without dropping it. So, I stuck my head over the fence and asked Stuart next door if he’d like to take the bike for its first ride, ‘yep’ said he. Stuart and his brother Adam were the guys that got the 74 TX650 of the trailer when I first brought it home. I remember Adam screwing his face up when he first saw it, asking ‘what is it?’. I told him it was a 74 Yamaha TX650, probably made before he was a glint in his father’s eye. ‘What you gonna do with that pile of $#it’ he replied. Anyway, I pushed it around to my workshop and started work on it, that was three years ago.

Anyway, when I rolled the Roll a Door up, there stood Stuart and Adam, helmets in hand. They’d heard it a few times when I’d started it up, but probably expected to see it in much the same condition, only now it was going. Both Stuart and Adam’s eyes popped when they saw it ‘beautiful’ said they, a number of times. So, Stuart donned his helmet and I grabbed my camera, too late, Stuart was gone, roaring up the street. But I managed to catch him on his second lap. On his third lap he never returned, so, Adam and I set off on foot to find him and met him halfway back, pushing the bike. When I looked at the bike, I noticed the fuel tap was off and said ‘you ran out of fuel, didn’t you’. ‘Don’t know’ said Stuart ‘it just stopped’. I then explained that old bikes had manual fuel taps you have to turn on and off by hand. ‘Oh, that’s different’. Stuart and Adam both ride modern technicolour nightmares.

Stuart pushed the bike back to the garage, about 100 metres. I turned the taps on, waited a bit for the fuel to go through and started the bike again. By the time I picked up my camera, Adam had jumped on and was taking off. I managed to catch him roar out the garage and up the street before stopping the camera.

When he returned, he was trying to find neutral, I said stick it in second then tap it down, which he did, easy peasy. So, if your XS650 is difficult to get into neutral, tap it down from second, never fails. I suspect the difficulty is because of the very short throw of the lever.

After Adam returned, I quizzed both on how it went: Brakes worked well, started easily, gears changed nicely, handled well around corners, seat was comfy, bars were in a good position due to risers, motor ran beautifully, everything worked well and best of all – the sound!

So, the 74 TX 650 has been roaded, nothing left to do. Perhaps!

Sorry about the sound, this tablet of mine makes everything sound like it’s under water.

An engine removal thingie I made. 'Thingie' is a technical term for engine crane. XS650 engines are a very tight fit in the frame, only mms to spare, if you want to work on anything aside from the clutch and alternator,the engine must be removed from the frame.
The Thingie works quite well: Lifts the engine and tilts it forward so it can be rolled away from the frame without scratching or damaging the paintwork.
The thingie also doubles as a work stand for top end rebuilds.
When I've finished with the current work, I'll modify the stand so the engine can be mounted longitudinally in the thingie and rotated upside down to disassemble the bottom end.
Once the motor has been disconnected from all electrical inputs and front, rear and top engine mounts removed, the motor can be removed from the frame in around 5-10 minutes.
