Radial Master Install

Years ago, I posted about using a 1/2" master cylinder and posted a long analysis of leverage ratios and finding a way to get a better feel with braking. Though I was able to have really fine control with light braking I couldn't get a really strong stop with the smaller 1/2" master cylinder piston but I didn't want to go back to the original 14mm piston until I read that a radial master cylinder is supposed to be better according to Google's AI search results:

A radial master cylinder can significantly improve braking feel by providing more direct force transfer from the lever to the brake caliper. This results in better modulation and feedback, allowing for more precise control over braking force compared to an axial master cylinder, where the force is redirected by the lever pivot. Radial master cylinders are generally more rigid, which enhances the crispness and consistency of the feel

I found this 14x18 radial master on Amazon and figured for under $50, why not give it a shot ?

Installation was super easy. The bleeder screw made bleeding super easy after I installed the hydraulic brake switch that I purchased separately.

A few adjustments to the handlebars to make room for the brake switch hitting the gas tank at full tilt and lining up the reservoir and I was in business.  Took a quick spin around the neighborhood and getting nice strong brakes with a 2 finger pull compared to 3 fingers with the old master cylinder.

Besides the mismatched levers, it's a great upgrade.  Now I need to address the clutch slipping issue and replace the clutch cable. 

I found this lever to be a higher quality component than the old 1/2" master I had installed because it had a loose and sloppy fit in the adjustable lever. This single lever costs a bit more than the adjustable 2 lever kit and the improvement in quality is evident in the close no jiggle tolerance and overall nicer build quality.

Universal Speedometer/Tachometer install

I wanted to replace my original speedometer and tachometer for something more compact. I'm not sure why, but the original 85mph speedometer always bothered me. I guess I felt like the bike deserved better even though I've only pinned it once in 10 years of riding.   After casually looking around and almost pulling the trigger on a cheaper universal speedo with an analog sweep needle for the tach, I stumbled across this product. It can be found in all the usual places such as Amazon and eBay but it's usually buried behind 2 or 3 pages of search results with vastly different prices ranging from mid 40s to mid 80s (US$). The description typically includes a listing of what each wire is intended to be connected to, but in typical fashion for these kinds of imported products the English translation leaves a lot to be desired. For example: the product detail notes: "Oil Quantity Indicator" as one of the display areas, but they really mean fuel level (my bike doesn't...

how to open your door when neither handle works

My recently acquired 2003 Honda Accord EX 4 cyl had a faulty door lock actuator in the front passenger side door.  Here is a run down of what I did wrong in case you find yourself in a similiar situation. Shopping for door lock actuators - Prices go from around $10 to over $40. I mistakenly ordered a pair of door lock actuators ($20 for left and right) for a coupe and received 2 black actuators that were not sized correctly for my 4 door sedan which has smaller white actuators. I did not discover the problem until after I had the door panel off and the actuator removed from the door latch assembly. It was hot, the flies were landing on me and drinking my sweat and I just wanted to button the door back up and stay cool inside so I searched for the closest parts store that had the part in stock and went there to buy it for $45. (I did return the 2 wrong parts but did not get a full refund, but I'm ok with that...$16 back in my pocket is better than $0) Reassembling the door l...

Nighthawk CB750 rear wheel swap part 1 - decision

I've always had a very slight side to side swaying sensation in certain conditions that I was not able to pinpoint.  It was especially bad back when I had a trunk/top case on the back of my bike.  An old timer on a forum noted that the tall rear tire mounted on a 16" wheel can get a little wobbly (concerning a top case causing 'sidewall flex, by increasing the leverage on the vertical axial moment of the bike') and that pretty much got the thought in my head to swap the rear wheel to a 17" or 18" at some point. the 1979 cb650 would have been an easy and cheap path forward since it's pretty much a direct swap to a 17" wheel with the advantage of the wheel design matching my front tire.  Unfortunately, those wheels were not cheap and getting more expensive by the day. I found 2 or 3 listings on ebay and was looking at a minimum of about $90 to get one shipped to my house and then I would still need to clean it and swap out the bearings.  Since I...
