In Guyana, South America, we just got a few shipments of SQ karts. The two-strokes are fantastic, but the started goes bad really fast. The Four Stroke on the other hand just doesn't have the kick i want. I pretty much cant afford any other chassis, so i'm wandering whether its worth buying the fourstroke and then changing the engine, and if so what engine would be best, or buy the two-stroke.
I want to eventually get a sponsor and move up to shifter karts. Need some help! Thanks!
