World’s fastest pre unit Triumph… since 1961

Sunday, Mar 05, 2017


From the 1962 Triumph Baltimore sales catalog

About a year ago I wrote about Gary Richards and his Speed Records at Bonneville in the 1960′s.

Still, no one has gone faster than Gary Richards did in 1961 with any 650 Triumph motorcycle without a fairing at Bonneville.

His two way average of 159.542 mph still stands as an AMA certified record to this day.

The fact that no one has been able to beat this record in 56 years is amazing in itself, however when you take into account his bike it is even more impressive.


His naturally aspirated stock rigid frame Pre Unit looked like a street bike, with a peanut tank and stock length fork. His father Rich Richards did the tuning, and they managed a 160.272 mph average over one mile, and a return average of 158.812 mph for an official record of 159.542 mph.

Most people don’t realize that the timing trap at Bonneville is one full mile long, and speeding up or slowing down will affect your average speed, which is then averaged with your  return mile speed to reach your qualifying speed.

This method of timing is significantly different than other speed events like the NHRA, which uses a 66 foot long trap at the end of the 1/4 mile track to calculate speed, or even El Mirage Dry Lake which only uses a 132 foot long timing trap at the end of a 1.3 mile track.

 Gary Richards currently produces Dixon Cylinder heads, and from 1961 to today is still the Bonneville record holder of the world’s fastest unfaired Triumph 650 of all time.

We have your Amal!

Saturday, Nov 12, 2016

Before you buy a new Amal for your Triumph, you may want to check with us first.

There are a lot of people selling Amal carbs these days, but some people are finding little value in choosing the lowest initial price.

Since most of these retailers do not deal directly with the factory, they sell the “base line” versions which are not specific to any model. Buying a pair of these will also mean you may have to buy jets, banjos, slides, or any other parts to tune them for your application.  This often negates the original savings. Some of these sellers also cannot offer tuning advice as they are inexperienced in these matters.

We know Amal carbs because we tune them, race them, and sell them…

We were the first shop in Southern California to have the Premier series concentric almost four years ago, and are still the number one Amal parts retailer here.

We have just received a shipment from Amal that has our specially built 930 Premier carbs for all single carb Triumph 650 and 750 models, and our specially built pairs for the 650 or 750 Bonneville. Also included in this shipment was Norton 850 Commando 32mm premier carbs, Monobloc 389 1 1/8″ carbs, and Monobloc 389 1 5/32″ carbs. If you need a new carb for your Triumph, it would be worthwhile to take a look at our online store

It would be a shame to build a high performance Triumph engine and never see what it is capable of. That is why the shop will be closed during Speed Week to support and tune our Pre Unit race engine at Bonneville for Nik and Patrick. The shop will open again on Saturday the 20th of August. Sorry for the inconvenience but I’m sure all gearheads will understand. Danpre_unit_triumph_el_mirage
