This motor is from my Private Reserve. I bought it around the time they were getting tough to get. It is the latest version with 3+2 Port design. In addition, it has the extra "windows" in the Piston and sleeve to assist fuel flow that the earlier engines did not have (view photo of P/S). Some of the Manufacturers specs. are listed below. This motor has only ever been taken apart to take these Pictures. It is as red'd from the manufacturer! Buy it here, and save a lot of money from the $500+ retail price range as posted on A.L. Website.
OEM Carb, Header, etc, included as in pictures and as supplied from the mfr.
Specs:
OPS .67/80
ABC Liner/Piston, OPS Classic 3+2 port design,additional piston and sleeve by-passes to increase power at top RPM by 10%, and to optimize cooling and lubrication of piston and rod.
Displacement-11cc/13cc
Power-4.35/4.65HP
Bore-24.58/27.00mm
Stroke-23.00mm
RPM-23000/23200
Weight-680/730g
THE DIFFERENCE IN THIS MOTOR FROM THE PAST MOTOR I LISTED IS THAT IT HAS BRAND NEW BOCA BEARINGS INSTALLED, IT HAS BEEN RETROFITTED WITH A K&B FLYWHEEL/COLLET/SPACER ASSY. (THE BEST WAY TO GO). THE OEM FLYWHEEL IS POORLY SUITED TO START A RACE MOTOR, AND IN MY OPINION, NOT THE CORRECT WEIGHT. THE MODS. I HAVE LISTED SOLVE THESE ISSUES. AND I AM INCLUDING A BRAND SPANKIN NEW RPM ROD (EMAIL ME FOR PIX). THESE RODS HAVE NOT BEEN AVAILABLE FOR MANY MANY YEARS. YOU WILL HAVE A NEW ONE! ALSO, PLEASE ASK IF YOU ARE INTERESTED IN ME BLUPRINTING THIS MOTOR FOR AN ADDITIONAL FEE! THE INTERNALS ARE AS "NEW". NOT TOUCHED INSIDE.
I have run these motors for many, many years (20+... I'm only 39 y/o!). They are very powerful. Let me know your application, and I can probably help you with the set-up. IF YOU WANT ME TO BLUPRINT THIS MOTOR TO WHAT I KNOW WILL WORK FOR YOUR APPLICATION FOR AN ADDITIONAL FEE, PLEASE ASK!
$335 Shipped to the U.S. Now $295
The link in Harry's post shows the NEW RPM Rod, and the flywheel assembly.
NOW INCLUDING A CUSTOM WATER-COOLED HEADER (a $75-$85 Value) for a Scale with purchase. Pictures of the motor and Header available upon request As of 2/17.
