Motorcycles from around the early 80’s until the mid 2000s generally used shunt-type regulators. Newer bikes tend to use MOSFET regulators. The MOSFET type are more efficient and run much cooler (this video does a good job explaining why). The good news is that virtually any older bike can be upgraded with a newer, MOSFET-type… Continue reading MOSFET Regulator Rectifier Upgrade
I wasn’t sure if there’s a lower temperature limit to spraying Rustoleum, but I took a chance. I needed to paint a steel cabinet. As night was falling, at a temperature of around 34°F, I sprayed Rustoleum Oil-Based (alkyd) enamel, thinned with acetone, using my trusty Harbor Freight HVLP gun. After sitting for a couple… Continue reading How Cold is Too Cold to Spray Rustoleum Oil-Based Paint?
I bought a cheap, Chinese MIG welder and needed some C25 gas. I wanted a cylinder in the 80 – 150 cubic foot range. I checked Airgas first, since they’re less than a mile away. The next day, I stopped at Industrial Welding Supply and was shocked at the price difference: Airgas Industrial welding supply… Continue reading Airgas vs Industrial Welding Supply
Here are two photos comparing OEM Honda Transalp instrument lights with the Jiawen T10 1.5W SMD 5050 LED instrument lights from DealExtreme (DX.com SKU 394964): Both photos were taken at 1/4 second at f/5.6, ISO 800. The bright spot in the lower (LED) photo is because the Transalp instruments call for one lower-wattage bulb, which… Continue reading Jaiwen T10 SMD5050 Instrument Lights (DX.com)
Spray Gun Options I’m reproducing a part in carbon fiber, which requires me to make a mold of the existing part. For accuracy and durability of the mold, it’s best if the first layer is sprayed gel coat. Gel coat is normally sprayed with a “cup gun” like the E.S. G100 Cup Gun. At around $175,… Continue reading Spraying Gelcoat Cheaply
I was looking for an EBC rear rotor for an RD04 Africa Twin, a bike which was never imported into the USA. No online shops in the country sold them, except, seemingly, one: TheRideStop. I put the item in my shopping cart and was shocked to see a shipping price of several hundred dollars. This… Continue reading Is TheRideStop.com Reputable?
I was putting new tires on my 1977 CB750. The rear tire went on and the bead set without too much difficulty, but the front tire was proving more troublesome. Previously, I had been running the Comstar wheels without tubes — something not officially endorsed until, I believe 1982 — and had used a bit… Continue reading Seating Tire Beads
In an effort to eliminate a front-end clunk when steering, I installed a new Moog track bar. The toughest part of the process is removing the ball joint from the frame mount. The ball joint is pressed into a tapered hole in the bracket, and this bracket makes it impossible to use a pitman arm… Continue reading 1995 Grand Cherokee Track Bar Replacement
