    Static ignition timing inquiry

    Hello, I just rebuilt my engine and replaced a fair number of parts, and I am now having an odd problem statically timing the spark. Known variables: I do not know when the last time the engine ran before I rebuilt it. I had Hugh's Handbuilt rebuild the crank, it is not rephased. I...

    Alternator specs

    Hello, I took some measurements on the alternator I have and I need to know if they are good readings. It will eventually get replaced with a PMA kit from Hugh's but those are expensive, I am broke, and they are out of stock at the moment anyway. So for now, I am hoping to be able to use this...

    Here are CAD files for the Blue/Gold spot caliper mount

    I have made a 2D template for cutting your own adapters to fit Yamaha gold and blue spot break calipers to 35mm forks. Feel free to edit them to remove a bit of weight, or change the shape a little, it's easy! The main thing is that the 10mm holes are in the correct place to seat the caliper...

    Nylon Screws in Southern Ontario

    For those of you doing the mod that requires M4x0.7 - 12 nylon screws, I have found a source in Oshawa that will deal with the public. There is a $10.00 minimum charge, though, fortunately if you are there in person they also stock carb cleaner, Gunk, etc., so after you spend .45 on three...

    An '81 H Pamco EAdv and HHB PMA I have been getting no charging of my battery due to no output from the stator. The other day I took the rotor off and inspected it. It was clean as could be, but the unit had gotten hot enough to melt the logo off of the rotor. I took the stator off and...

    Front rotor (disc) dilemma, or "am I looking for something that does not exist?"

    Building a bobber, purchased the front end separately and it came in a pile of bits that look to be from different bikes. Forks look to be XS2 or TX650 (because of the speedo drive cable position I guess the pre 77 brake caliper goes to the front of the forks. Dilemma is in - what rotor (disc)...
