Running an EFI 1010 with single pipe and can. Intake is all stock. Looking to hit 79-8000 rpms as it appears that is where this engine shines. Running 20/39 gearing with a 144x16x2.5 track. Would like to get the clutching setup for 7-9000 feet? Also a setup for flatlanding (sealevel)...? I've gotten some ideas but would like to see if any of you running the 1010's can give me a general idea. I'm not a real big guy either(180lbs). Running stock primary and secondary cat clutches. Thanks!
