    Nice! Mine is too, even if it looks far from complete. I have a parcel waiting for pickup with rims and spokes, fenders and body panels, lights, a TT alloy tank with no dents even. I’m making my 77 XT look like a 77 TT500 in el toro orange

    Tank is painted in 78 comp yellow but I’ll fix that soon enough

    Nice! That year TT was the best looking to me.

    Did anyone ever offer a solid state ignition for these things? One morning in the Cascades I about kicked my lungs out trying to start mine before I finally gave up and pulled the point cover off and hosed the assembly off with WD-40. Then it started right up.

    Yes, Rex Speedshop has a 12 volt conversion kit that includes an electronic ignition that totally does away with the points plate and mechanical advance. I intend on using it on this bike

    On my 81 I swapped over the entire ignition system from an SR500. Stator, rotor, CDI. I love how bright my lights are now! And actually, I got my CDI from Rex’s Speedshop and it works great!

    The 80-81 US spec XT came with an electronic ignition system from the factory though, but it was 6v.

    Here is a picture of my very first adventure bike: 1978 Yamaha XT500 Enduro: the ‘Vagabond’. Drum brakes, points fired magneto ignition, 6 volt electrics and kick start with a manual compression release. Emgo tank bag courtesy of JC Whitney. A mismatched for color Don Vesco ‘skinny-fat’ tank borrowed from my TT500 Yamaha for that extra long range. All the rest came out of my head and Minnesota Fabric,Joanne Fabrics, Cabela’s mail order and ACO Hardware. I rode this bike out west to see the USA forty years ago. It got about 65 mpg at 65 mph. (Oh I cannot forget Melanie, one of (this old) man’s best friends.) 34007F72-5A17-4F6F-832C-989CBC9F4A52.jpeg

    I scored a slip on for a cbr600 from cl for $30. Shortened it, eliminated the resonation chamber, made a 1 3/4" inlet, and fabbed a mount. It runs much better than the $200 3" steel supertrapp I tried first. (The supertrapp discs aren't the same as the old ones) IMG_20190816_172004773.jpg

    Thought I'd make myself official on the XT500 thread here.

    IMG_3049.JPG
    Bought this bike as a roller and half ass abandoned resto-mod. PO owner had done such great mods as spray painted the frame and motor...WHILE STILL MOUNTED. The tank is also repainted, and some jag-ass thought he'd paint it silver instead of leaving the bare aluminum and clear coating over that.

    That said it had a brand new Mikuni VM38, Kedo/Supertrapp exhaust and header, Progressive shocks, and some other bells and whistles ready to go.

    I added Rex's 12v conversion, new tires, and still couldn't get it to start. Turned out the PO had broken the cam chain, so apart the motor came. Found I needed some cylinder work too, so found a 10:1 Wiseco piston and bored 2nd over, and dual feed oil line. I replaced some things as needed while I was in there, and it ran OK for about 200 miles, and then the smoke started....

    Long story short, I'm investigating whether I'm getting oil or not. New rebuilt head, cam, and rockers on the way.

    Nice looking XT! I'd check the screen at the bottom of the frame oil tank, and drop the sump cover and clean that screen there also. The oil pump is easily accessible for maintenance on these motors.

    TT/XT hybrid, tt frame with XT motor and wheels. I wanted the cush drive XT rear wheel, and the bigger XT brake on the front wheel.
