How to stop oil leaks including areas not catered for on early machines like gear and kickstart shafts.

Top condition gaskets and seals are a must but wonÕt last long if the crankcase breather is malfunctioning. Why timed breathers are better than untimed, how to measure and adjust the timing, one-way and reed valves.

Why you should check your valve timing and not rely on marks on camwheels. How to check and set it accurately.

Valve lift graphs showing quietening ramps, how sports and touring cams vary.

Methods to reduce vibration and lessen its effects.

The baffles in many pattern silencers are just a guess at what might work and harm performance and cause vibration. I have developed and tested theories about exhaust systems and turned this into guidelines for silencers that work.

Plus the effects of balance pipes and anti-reversion devices. Before crank balancing or pulling the engine apart - read this book!

Sent Wrong Pieces
Size: 1 Panel, Size: 1 Panel
I really, really wanted to like this - and, in theory, I really, really should have! The instructions were easy to follow and assembly took about five minutes. The assembled screen is lightweight and easy to move. It was a great size and exactly what I was looking for except....I wasn't sent the correct pieces. Instead of receiving 4 elbow pieces and 4 feet, I received 2 elbow pieces and 8 feet - meaning that the bottom part of the fabric just hangs there and, overall, the divider is extremely unstable because there is no horizontal support on the bottom. Thankfully, there are Velcro tabs on the side of the fabric so I can use it if I don't plan to move it even 1 cm, but otherwise, what I received is not usable for what I needed it for. Additionally, the fabric is made of polyester and catches animal hair very easily. Had I received the correct pieces, this would be a good buy for the money. Unfortunately, overall, I'm disappointed.

Works great, keeps the light out of my eyes and easy to put together
Size: 1 Panel, Size: 1 Panel
I got this room divider in and it works great. It’s really easy to put together you don’t even need tools. I really like that it’s not see through, it’s not a black out curtain but it keeps light out pretty good. I absolutely hate my bedroom layout there’s no bathroom door. My girlfriend and I have different work schedules so I’m trying to sleep while she’s getting ready for work and the light shines right in my eyes. This divider keeps the light out of my eyes and that’s exactly what I was hunting for. I also like that you can adjust the length. I took one of the bars out to make it a little shorter and it worked great. I would recommend this room divider.
