Thank you !!

VM34mm carbs from Hoos on a stock motor. Default jetting from Hoos. See pic for exhaust set up. Bike runs really well for spirited riding, always starts immediately. I set up a wideband AFR meter. Generally runs between 12.5 and 14.0 which all feels good. Heavy throttle stuff ~13 Except...

As a matter of interest, took a peek at my '74 TX650A. Red is AC probe from one of the 3 white stator wires. Blue is AC probe from the power bus at fuse box (only shows the variance around the 13.5v DC it was idling at). Red shows stator events and blue shows the ignition events (including...

Hydraulic clutch conversion: When I first got the bike, the clutch was a mess. I could sorta adjust the cables and worm, but everything was worn out and had to shim a bolt on the cable and the lever felt wonky. After adjustment, it was a brutal pull and the cable would rise up like a popped...

Is idle getting high only after warmup? Spit balling here, but aluminum expanding causing an air leak? Sounds like maybe from an oil passage? Good luck, you’ll get it.

I suddenly wanted to get an XS650 this Summer and blindly bought the first project I found. I knew nothing. 74 TX650A. Advertisement said abandoned project and it only needed a seat and taillight, it had new flat slide carbs and electronic ignition: Simple enough? I was out of town at the...

Oversimplifying thermal dynamics is Jedi work. But @TwoManyXS1Bs is exactly right. Jedi? Heat travels fast through minimal mass and travels slower through additional mass. Heat dissipates from surface area. Most heat sinks are designed to maximize surface area with a fast path to get there...

Yamaha almost did it in ‘72 on TX750 platform. RZ201 prototype...

Cheers to good health ! Hey, I have a question: do your shoes plug into something? Hope you don’t mind me asking, but it looks like something special going on.

Feels like you broke a rule, what with no pictures and all...

I almost ordered that voltmeter. But I got the round one that’s also all over Amazon. I thought maybe, just maybe, it would fit in that bung hole in the back of the headlight housing. When I got it, I had to laugh. Fit perfect, 30 second install lol. Easy to read in daylight, and seeing good...

New In Box solid state regulator rectifier for older 1970-79 ‘B style’ regulator (sends positive voltage signal on green wire to brushes to activate magnetic field instead of ground signal). For sale $85 includes shipping. Unopened and brand new. Includes solid state unit and connector kit...

Installed. Pure butter. No mo slip. Installed with Barnett 501-58-06045 springs. Most importantly though was how silly the old springs were. See photo of new and old: Note the warning on the package that in California these springs may cause reproductive harm. Next, I was expecting a dot...

Ah got it... I had the wear direction reversed in my head. Will adjust. So slick, nice work! I saw that when I was clicking around for ideas. My style. If I had access to more than a drill press...

I bought a project bike, history unknown, it has been sitting for years. I rebuilt nearly everything but I did not go into lower crankcase or take off right side cover. Oil I used is 20/50 Valvoline ‘racing oil’ (full dose of zinc) I milled the left cover and put a VTR1000 clutch slave on...
