Default G26 Soup-up

This modification takes the G26 up to 30.5mm using a 30mm crankshaft and 36mm piston.

Picture #8 shows arrow on piston this must point towards the exhaust side.

Picture #9 shows lug that needs to be trimmed off.

Also converted to electronic ignition.

Stock prop is 16/8 should be able to swing a 20/6 now.

Testing to commence next week.

Peter, How did you get the wrist pin clip rings in? Do you have a tool to do it or do you just start pushing them in and hope for the best? Dan.

They snap in easy. Just start one end and work your way around with a small screw driver.

Thanks for posting this, makes a nice upgrade.

Where did you source the parts? 

Why was it necessary to remove that lug?

Whit,

Parts are from Dave's Discount Engines.

Modifications to cylinder and ports are done by ESP (Earth Surfer Products).
To accommodate the longer stroke the combustion chamber is raised up 1mm instead of stacking gaskets under the base of the cylinder.

The lug (which is not used) has to be removed to clear the original magneto housing.
