Purchase 2 Stroke Spreadsheets


If you are not good at computers then just pay the price of the desired program and send me the needed details and I will plug it into the program and tell you the results and work with you for the best solution. No problem, I'm here to help.

My favorite saying is "If you want something done right you have to do it yourself". Like the Nike ad says "Just do it". Buy the software. Don't worry, if you have any problems I can talk you through them. I'm here to help. I want you to be successful at improving your ride. I tell you it is an amazing feeling riding a bike that has your own design changes on it. Just amazing. Can anyone do this? Yes, of course! I knew nothing about metal works when I started out. But then I sculpted my own head with squish band, made a boost bottle, balanced my crank, ported the cylinder, and made my own pipes. Turn the page to a new chapter in your book of 2 stroke experience and buy it. Live wide open throttle!

They also work on most cell phones with Excel or Open Office. Click here to download a sample Excel spreadsheet to see if it functions OK on your computer or cell phone.

GUARANTEE: If you don't get good results then I'll give you your money back. But before doing anything you'll need to email me the spreadsheet so I can make sure you've used it correctly.

get it thru PayPal: Just email me what you want at 19jaguar75@gmail.com* and just send the right amount of money to my Paypal account at that email address and I will email you the spreadsheets. Click onto the product name (above the screen shot) to learn about it before buying. These work on both Windows or Macintosh if you have Excel. (The only difference is some coloration of cells and page sizing.)
* If I don't answer in a full day then email Paul, my best friend. Make sure he is available with something like "Can I buy the 2 stroke software from you?" and if he answers yes then you are set to go. Just send the money to his Paypal account lazylightning@mail.ru and then he will email the software to you. This alternate source exists because I have a bad heart and could go at any time and I hate to think that my software would stop being available. He only has the Windows and Open Office versions of them. He doesn't have the high RPM version of pipe calculator.
