Attex Engine Swap Help Needed

[Brock Landers]

Hi, I have an Attex Super Chief 500 and I am sick of messing around with the temperamental Arctic Cat 2 stroke that is in it. I have a good running Kohler Magnum 18 that I want to put in it. I'm more into torque than speed anyway. Can someone tell me what drive clutch I need to buy for it? I guess I have to get a new spring for the driven clutch on the T-20 also? The Kohler has a 1" shaft on it although everything I have read says it's supposed to be 1 1/8". Any advice would be greatly appreciated.

You don't have to buy the "red spring" from Recreatives, but it will improve your performance. The red spring will keep you in a lower gear ratio longer. The one you have now (probably yellow) is meant for higher rev motors like 2 strokes.

Thanks, Buggyman!
