Let me introduce myself:....

I'm the owner of TSR Two-Stroke Racing Software.

I have accumulated 40 years experience designing, building and racing 2-strokes. I have been a Desert Racer, Hill Climber, an all around dirt bike rider, and a USA and World Record holding DRAG BIKE RACER. I have built engines, pipes, etc. for World Class Riders such as the following:..........................

Kenny Roberts.. USA NATIONAL CHAMPION ..AMA Dirt Track

Note :..Kenny R. is also 3 times WORLD CHAMPION

Wayne Rainey...WORLD CHAMPION....................Road Racer

Note :..Wayne R. is also 3 times WORLD CHAMPION

Eddie Lawson.. WORLD CHAMPION ....................Road Racer

Hank Scott........ USA NATIONAL CHAMPION ..AMA Dirt Track

Gary Scott......... USA NATIONAL CHAMPION ..AMA Dirt Track

Steve Eklund .... USA NATIONAL CHAMPION ..AMA Dirt Track

Plus many, many more at the local level, in ALL types of events around the country. Too many to list.

Note:... TSR was also formerly known as Turners Expansion Chambers, and Turners Two-Stroke Racing for you older racers... :-)

I have designed engines and expansion chambers for several leading companies in the USA, making them a lot of $$$. The longest was over a four year period for a major USA MX pipe mfg. I also designed pipes for a leading Snowmobile pipe mfg., and who now has my software. I have been consulted by lots of Top Name 2-STROKE Professional Tuning shops such as some of the HUNDREDS of program buyers on the SHOP list on the Quote Page on this site.

"PLUM CRAZY" in Action

My computer experience started in 1984 to fill my need GO FAST Drag Racing, & to get the math done much quicker than the old calculator method. Sorry, I'm not a PC nerd, but I do see the value in computers as very powerful number crunching tools, with the right software. I first had to learn basic computer language to begin programming the PC, read NOT EASY. This is an on going process to stay up with the changes. The software will never be finished as changes are made to keep up with HP race, and engine design changes. The results were developing software that is user friendly and works very well in developing proven race tested engines, including my own World Record holding Drag bike. I started with a Yamaha RD 400 street bike that ran 90 mph in 14 seconds in 1/4 mile. I cut over 4 1/2 seconds, added 47 mph and It has now set 49 NATIONAL RECORDS and the multi-WORLD RECORDS (Record set at 9.681 at 137.24 on a N.H.R.A. Sanctioned track). It has held them over 19  years. Yes, the Drag bike was a Crotch Rocket. My Yamaha RD424cc twin that ran a best time of 9.67 E.T. at 137.24 MPH, ( on GAS -- No Full Fairing -- No Nitrous -- No exotic fuel -- No auto transmission -- No Straight cut primary gears --- No stutter box -- No Two Step  -- No rev limiter -- No shift light and No onboard computer ). Even if someone finally goes as quick and as fast today, it's Many, Many Years TOO Late. Why couldn't they do it in mid 1980's? Today it would be "easy to go this Quick and fast with my TSR software.

Records are made to be broken ... but we will always be the first in mid 9's !

"Plum Crazy"

I also applied for and got membership into Society of Automotive Engineers. (SAE) about this time in the 80's.

 I am not a college made Engineer, ....but I've sold my TSR Software to many Engineer's.  

Having proved the value of this software on the race tracks, I decided, in January of 1992 to offer this New TSR Software to other tuners to aid in the advancement of 2-Cycle Engines. The SHOP interest, as well as private tuners, has been overwhelming to say the least. Hundreds of shops now use these great tools. Yes I said TOOL, it's like a good lathe, you can turn out junk if you make it to do dumb things or you can create a mechanical piece of art. I will be working on more as the need arises to keep up with the new technology.

After selling the TSR Software for almost 2 Decades now, we have established a base of 600 plus Shops and Thousands of Private at Home Tuners.

Note :..Everything you see on this site is a product of my learning curve, from the learning PC's, learning PC programming, learning how to build a web site, learning graphics through doing artist type drawing, on and on. Makes me tired wondering where the time was found to do all this, but very rewarding for sure.
