This is a 1974 Yamaha TX750. No title. As is $200.00. Pretty complete except for stock air boxes. Engine kicks over, good compression. Shows 39,000+ miles. It's in Tucson AZ, PM me if interested.
Those are great bikes, if you wrap a chain around them they will anchor a fair sized boat.
Actually the front and rear wheels are useful to a dedicated XS650r and the rear swing arm is a subtle bolt on performance upgrade (larger size tubes = stiffer)
The rear wheel is an XS650 bolt on and has a larger drum brake than the XS650.................
The rims are Akronts IIRC and are rather nice.
If I remember correctly the TX had a chain driven counter balance. The chain would fail, the counter balance would hit rotating engine parts and the engine would self-destruct. Yamaha had to replace hundreds of engines.
the 73 had a shallow sump and the the chain driven omni-phase balancer, which smooths out vibration from the big parallel twin, also frothed the oil to the extent that the crank was starved. The solution was simple--fit a deeper sump. They also solved the counter balance chain problem as well. Here is a link to mods that Yamaha asked the deales to do but according to this article a lot of the US dealers didn't do it TX750A The 73 had an automatic adjustment on the chain for the balancer, that didn't work properly. It was changed to a manual chain adjuster on the 74 but by then the reputation was shit ..........
It's amazing that any of them are still around. Back then I often did work for our local Yamaha dealer. I had intended to trade my XS2 for the new TX750 but he stopped me. When the authorized dealer doesn't want to sell you a bike, you know it's bad...
If there's fans here, I think I know where two of em are hiding. and possibly a third frame, engine hulk. But you really got to love em. twitch, tic, twitch.
