    Anyone with Microsquirt experience on an XS?

    Nope But someone's done it. https://www.msextra.com/forums/viewtopic.php?f=104&t=69408 I have NO idea what any of that means. 🤣🤣🤣

    XS650 Engine Parts Year Range

    Drill down to your bike/year on www.partzilla.com and then through to any specific part. Scroll down, and there is list of where the part is used listed by year together with where it is used on other Yamaha models. Any part with the same part number will fit. Does this help?

    Petrol prices

    Absolutely. Energy is the universal resource. In so much as when it is cheap and reliable and readily available then everything is correspondingly cheaper and more readily available. I highly recommend Alex Epstein's book, The Moral Case for Fossil Fuels...

    1977 "garage find"

    @TomMead come back. We're back on track. (It was like two bald men fighting over a comb in any case). Yep. People like the 75 because of the paint job but the 77 was the bees knees most people agree. My advice? What was told to me when I started. Get a multimeter clean all the bullet...

    Jeez, I love this forum. Everyone is so polite. Perhaps it's because we're old with nothing to prove? @RustiePyles you probably know more than I ever did. Dave

    The "push" is provided by the voltage, which 12V in both cases. The same push into the same component the same current. "Voltage, electric potential difference, electric pressure or electric tension is the difference in electric potential between two points, which (in a static electric field)...

    1977 "garage find"

    A device on the bike (or anywhere) that operates at 36W when attached to a 12V source draws 3amps in current. Watts = Volts * Amps , 36 = 12 * 4 using Ohms law or We can calculate the resistance of the device. r = 12/4 = 3 ohms. This is fixed (it varies by temperature, so in a bulb it...

    Yeah, a car battery is twelve volts. The fact that it is bigger and holds a larger charge is immaterial. The standard advice is not to run the car engine. But this is likely because we don't know what the range of voltage that an unknown car's charging system will deliver. So, better to err on...

    Green number plates

    All very nice. But these are weasel words. Any measure which privileges electric vehicle owners will of necessity detriment drivers of non-electric vehicles.

    Clutch worm gear

    I was just reading about this yesterday. The poster was fitting a Suzuki GT worm gear into a CB350 for a racing application. Hope this helps. EDIT: This might help http://forums.13x.com/index.php?threads/honda-cb350-clutch-worm-drive-modification.314751/

    Orange Cycle Parts Gasket Scraper by Motion Pro 08-0601

    I used some copper pipe, cut and filed to a chisel end. Copper is softer than aluminium and so can't damage the surfaces. Also used paint stripper and ws40 to soften the gummed on gasket. (copper pipe can be found in nearly all skips :laugh: ) Dave

    Led Blinkers (that work) but led turn signal indicator in center column.

    I'm far from being an electrical expert but the LEDs are Light Emitting Diodes. A diode is an electronic device that passes a current only in one direction It is like a one way valve. So provided you get the polarity right the bulbs will light as before on the left and on the right hand side...
