We are pleased to announce that our first book, "The Four Stroke Dirt Bike Engine Building Handbook" is officially released! The DIY Moto Fix team is very excited to launch our first book, but we are more excited to have riders like you benefit from it during your future builds.

This book is an incredible source of professional knowledge for beginners and experts alike. In order to benefit you and your personal riding needs, I have included in-depth information specific to those building a stock engine or a performance engine. The chapters we feature take you through the entire process of an engine build with full color pictures and descriptions, including disassembly, inspection, final assembly, and engine break in. I also feature chapters that outline how to properly use precision measurement tools, how to diagnose problematic engine symptoms, how to determine what performance parts are best for you, and how to know when it has come time to rebuild. 

Take a look through the Table of Contents and some of the interior pages to see for yourself...

What precision measurement tools should you use
This post was originally published on ThumperTalk and can be viewed by clicking here.

As we wrap up this final post on precision measuring from my Engine Building Series, I would love to take a moment and tell you a little bit about the book I just published, The Four Stroke Dirt Bike Engine Building Handbook. As someone who has been following the DIY Moto Fix Engine Building Series posts, I think you're going to love the in-depth knowledge and information provided in this book on dirt bike engine building. 

The Four Stroke Dirt Bike Engine Building Handbook provides incredible insight on the process of building a four stroke dirt bike engine. I wanted to bring at-home mechanics the level of expertise present in the industry when it comes to engine building, and do it in a way that is accessible and easy to understand. 

This book is presented in a format that helps both beginners and experts. I not only write about the correct way to rebuild your engine, but also present the technical reasons why things are done the way they are in the engine building world. In addition, I supply information not found in service manuals for building high performance racing engines. Reading this book will also prevent you from making crucial mistakes that many at-home mechanics unknowingly suffer from when rebuilding.

Writing this book has been such a blast and I know you will benefit from its immense value if you are planning a rebuild. Here are a few pages from the book to give you a sneak peak on the massive amount of technical content provided for dirt bike engine building enthusiasts.
The Four Stroke Dirt Bike Engine Building Handbook is available in both an eBook format and a printed and bound version. Check the book out and learn more by clicking here.

Thanks so much for your support and enthusiasm for DIY Moto Fix. Read on for my final post on utilizing the remaining six precision measuring tools.

Plastigauge

Plastigauge is one of the only measurement tools you won’t mind throwing away once you are done using it. Plastigauge is a measurement tool used to check the clearance between parts. The plastigauge consists of little strips of plastic which are inserted between two parts. Once assembled the plastic strip is compressed. The amount the strip compresses can be measured and correlated to a chart (supplied with the plastigauge) which defines the clearance for the measured compressed width of the strip. For engine building purposes plastigauge is ideal for checking clearances between engine components utilizing plain bearings. The plastigauge is a great tool for confirming clearance and measurements.
How to use Plastigauge
Another plus is that unlike most other measuring tools, plastigauge is cheap! Plastigauge is usually sold in an assortment of sizes which cover multiple clearance ranges. Plastigauge strips will come in different diameters and each diameter will be capable of measuring a certain clearance range.

Where to Use: Examples include cam to cam journal clearance, crank bearing to crankshaft journal clearance, and crank pin to rod bearing clearance.

Calibrating Plastigauge

Finally a measurement tool where no calibration is necessary. Just make sure you choose the appropriate size strip for your application. Also make sure the plastigauge is fairly new. Plastigauge does get old after awhile and using old plastigauge may not yield accurate results.

Reading Plastigauge
1. After the plastigauge has been compressed use a calipers to measure the width of the compressed strip.

THE TOP 10 SIGNS IT MIGHT BE TIME TO REBUILD YOUR DIRT BIKE ENGINE

when should you rebuild your dirt bike engine
When to rebuild your four-stroke dirt bike engine? This is a great question. First, we need to determine how to know when the right time comes to rebuild your four-stroke.

 Engine wear is directly related to RPM and mechanical stress, so riders engaging in riding where the engine is on the rev limiter frequently, the engine is operating at a high RPM without any load on it, the gearbox is loaded or unloaded abruptly, or gears are selected hastily will require the rider or mechanic to service the engine frequently.

Q & A // How Do You Fix Radiator Leaks?

How to fix a radiator leak on a dirt bike
Every once in awhile you may find that your bike has a fetish for getting close with immovable objects, like trees or rocks, no matter how you try to prevent it. Most of the time this isn’t too big of deal, but occasionally a damaged radiator and subsequent coolant leak will result. This is a big downer. Radiators aren’t cheap to replace! Luckily, some leaks can be repaired if they are small and happen to originate in a favorable location. Not all leaks will be repairable, but once the radiator is leaking there is no harm in finding out if you can repair it yourself.
