This book is not the comprehensive guide that some people may be looking for but it does provide one more set of data points. I found the discussion of ignition options and the Miata seat conversion to be worth the price of the book while I was dismayed that the only Weber carbs reviewed were the triple 40/45 DCOE's that require extensive engine mods, with no mention of the dual DGV option that would work better on a road car. Many of the parts for suggested upgrades are from small UK suppliers that US readers may find difficult to access. If nothing else it is an interesting read and will provide food for thought while the New England permafrost sets in.

Typical of most of Roger Williams' books, he fails to provide factual content behind the improvements mentioned in the book. Rather, the book does not actually explain "How To Improve" your TR6, but rather it glosses over the products available from a handful of UK suppliers while largely ignoring the offerings of other suppliers and also ignoring every US based supplier of uprated components.

Want to know what camshaft / carburettor combination is right for you? Do not bother with this book, there are no answers for you here. Want to know which tubular exhaust manifold you should use, afterall there are at least 12 different ones available between the UK and USA. Williams only presents one these manifolds and barely goes into detail.

A waste of $20, Roger Williams' give me my money back!

Very good book clear and understanable advise with lots of pictures a must for any triumph enthusiast.
