This classic has been completely updated for the second edition. John Robinson, the Technical Editor of `Performance Bikes', explains how various stages of engine tune are reached, and describes typical development work with enough theory to devise apractical development programme. The phenomena described are all known to work - the trick is making them all work together.Engine development is slow and expensive, but the results can be very rewarding, both in competition and in the sheer pleasure of using a motor which is crisp and perfectly set up. Although it is not possible to make all-round engine improvements, other than those gained by careful assembly to the exact stock tolerances, improvements in one area can be `traded' for losses in another: increases in high-speed power balanced perhaps against losses in low-speed power, engine flexibility and reliability.John Robinson takes the reader through the processes which are necessary to make your four-stroke run perfectly.

Very nice shirts
Size: Large, Color: White
These are a heavier fabric than I was expecting but that’s fine since it’s winter.
They barely shrink being washed in hot water and dried in a hot dryer. I was actually hoping that they would shrink a little more after losing 40 pounds. But they shrunk just a little and they fit just fine.
Also, if you take them out of the dryer immediately there are very few wrinkles.

Dress shirt
Size: XX-Large Big Tall, Color: Powder Blue
The material is a nice quality and the color is very close to the picture but I think it’s a bit darker in person. It definitely doesn’t fit like a “tall” should though but I think if we would have sized up it would have been to big. Overall it was an ok purchase for what we needed it for but it is a bit short.

Fit check = great
Size: X-Large, Color: Light Grey Vertical Stripe
Happy to finally find a great shirt fit for both business and casual looks. This shirt line is made in Sri Lanka (not Bangladesh). It has a great fit around the shoulders and chest for a 40 year old American male. It fits true to form and was recommended to me directly by Grok AI based on my exact waist, chest and neck measurements. It doesn't pull tight across the chest, and fits really nice with a sport coat. It's comfortable and breathable, the fabric is thick and high quality. You can wear this tucked or untucked depending on the attire you need. I bought 2 and will definitely buy the rest of the color line up. I'd love to see more colors and patterns available in this fit.
