Can I flip the cylinder head?

[homejones]

Hi, I know I've seen this before on this forum, but can't seem to find the thread now.

Anyone ever tried to flip the cylinder head so that the carb is facing the front of the bike? Any problems doing this?

Thanks!

Flipping the head won't do that. Flipping the cylinder jug will. You'll also have to rotate the piston and do a little port work.

If you type "backwards engine" on the Google search above the forum header, you'll get all kinds of results.

Perhaps most notably: http://motorbicycling.com/f38/backwards-engine-experiment-1939-colson-13458.html

Norman was the first to do this. there are a few out there. Bairdco and mine are others . Its not that hard to do if your mech inclined and have a dremel tool to do the port matching on the case.They are a little harder to start after this mod. but the results in the way they run are noticeable.You will probably have to make your own intake too. Good luck
