Chonda Port Matching

[Mike Powell]

Had a blast on the new Chonda last Sunday and ran all morning wihout a hitch, and burnt about a gallon of gas!

When I built the engine, I matched the exhaust pipe flange to the exh port on the engine, (huge difference in size and shape). However, going through some of the earlier posts, there is mention of matching the intake port... is this allowed under the current rules?

I don't know how fast it is, but I'm looking forward to getting in the fray next week... and fnding out!

Make sure the intake gasket does not intrude the intake path (by positioning it properly, and installed in the right order, and right side up.) Absolutely no modifications are allowed to the cylinder head on either the intake or exhaust side.

You may port/machine/modify the HEADER side of the exhaust (the header itself) to your hearts content. You may also modify the gasket as needed, but there is to be NO modification to any portion of the motor, the head, the exhaust, or intake ports.

The jets have limits, and the emulsion tube must be stock. Also the black plastic carburetor insulator must be stock with no modifications of any kind. The restrictor, if used, must be installed closest to the motor with gaskets on both sides. (cylinder head, gasket, restrictor, gasket, black insulator, gasket, carb)

Thanks Eric... that's kinda what I thought....

I was wrong on this order. It should have read:
