Ken's Valve Spring Compressor

Submitted by xjcdadmin on Tue, 02/23/2021 - 01:14

Here are a couple of pics of the valve spring compression tool I made.
It is a 3/4" x 4" pipe nipple that I bought at the local hardware store for 0.89$ + taxes = 1.03$ (Canadian) and a woodworking bar clamp.

Cut a slot down each side of the nipple about .25" - .375" wide and made the end which will sit on the spring a little larger, like a pear or tear drop.

Drill a hole thru the nipple at the other end so you attach it to a bar clamp with some wire, allowing you to have two hands to compress the spring.

Repairing Second Gear

Submitted by xjcdadmin on Mon, 06/19/2017 - 00:20

Note: this fix does require mechanical ability and judgement. If you have never done anything like this before, you may decide to disassemble the transmission yourself (hey, everyone has to start somewhere) but I suggest you seek out the assistance of someone with some mechanical experience once you get inside. Just changing/repairing the gears may not be enough.

Problem: The transmission kicks and jumps out of second gear, under load. This rapidly gets worse and soon the bike won't take second gear at all.

Replacement TCI Transistors

The original transistors used in our Transistor Controlled Ignition igniter boxes are Fuji made ETD41-035. They were discontinued many years ago.

Various sources dedicated to old Yamaha motorcycles such as the Vision and the Virago suggest that the MJE5742 is a drop-in replacement.

For many years my Police Special had a very nasty habit of dying like I had hit the kill switch.
It never sputtered first and would almost always do it within the first 1 km from my home.

Several years ago the ACEM conducted the Motorcycle Accident In-Depth Study. Attached is the final draft of that report. It should be required reading for all motorcyclists!

Replacing Ignition Wires in Stock Coils

This is the 5th set of Yamaha coils (4 XJ sets and this MaximX set) I have repaired this way. I have tested a set (engine running) with the full force of a pressure washer. I highly recommend this to anyone who is having problems in wet weather. Net cost is about CDN$10 per set -- 30 if you buy new NGK resistor caps too. Compare that to the cost of a new set of coils!
