I've go my three 97's set up and all is running well. Rebuilt by Uncle Max. Used a unisyn to balance them out. Great response, starts easily, plugs look good, etc. My question is: When I put on the air cleaners there is a noticable change in engine RPM. I'm using the bonnet type air cleaners with louvers and K&N filter elements. My concern is that this will cause a rich running condition. Any suggestions as to which type of air cleaners are best to run. Frog Mouth, Velocity Stacks, etc. Thanks for you inputs.
