13/40 final transmission gears with 13/39 sprockets gave me ratios that let my Yerf crawl up anything the tires could hold. Dr. Pulley 12g sliders in a Koso 115mm variator with red main clutch pulley spring was all that the CVT needed.
My engine was not bored or stroked and did not run a decked or ported head, but it did have a low restriction exhaust with 1" header pipe and a redneck UNI fresh air intake tract.
22" tires on all four corners allowed me to roll over obstacles instead of getting hung up on them. Front: 22x8-10 tires on 8x10 3+5 rims, Rear: 22x11-8 tires on 10x8 4+6 rims
Ignition was boosted with a Iridium spark plug, Orange coil and MRP adjustable yellow CDI. I didn't notice a difference from stock ignition unless I was winding out the engine.
