Difference between the OS 70 and 70II
Hi all,
Can i know what is the difference between the OS 70 and No OS 70II surpass?
Manufacturers say that OS 70II you get more RPM . IS it true?

Difference between the OS 70 and 70II
Here are the details of what's different on the O.S. Max FS-70 Surpass II:
New carburetor and tapered needle for smooth throttle response.
90-degree pressure fitting in crankcase routes blow-by to intake
manifold, resulting in a cleaner running engine.
Carburetor is mounted on centerline of the engine.
Both carburetor adjustment needles are located on one side of carburetor, for easy adjustment.
Black anodized rocker arm cover.
Larger muffler for quieter operation.
Crankcase vent is now connected to the intake manifold by silicone tubing. This keeps the inside of the cowling cleaner.

Hi again
Dear Bax,
Does it makes any difference in performance and speed having the Carb on a centerline. IS their any difference between the RPM between both 70 and 70 II.
After the OS 70II surpass I have now bought a Magnum 91 FS. Is it a good engine?
Thanks
Sharad
